The CCMP datasets combine cross-calibrated satellite winds obtained from Remote Sensing Systems (REMSS) using a Variational Analysis Method (VAM) to produce a high-resolution (0.25 degree) gridded analysis. Wind directions from the resulting analysis are assigned to the location and time of the satellite-derived wind speed observations to create this value added dataset. The CCMP data set includes cross-calibrated satellite winds derived from SSM/I, SSMIS, AMSR-E, TRMM TMI, QuikSCAT, SeaWinds, WindSat and other satellite instruments as they become available from REMSS. REMSS uses a cross-calibrated sea-surface emissivity model function which improves the consistency between wind speed retrievals from microwave radiometers (i.e., SSM/I, SSMIS, AMSR, TMI, and WindSat) and those from scatterometers (i.e., QuikSCAT and SeaWinds). The VAM combines these data with in situ measurements and a starting estimate (first guess) of the wind field. The European Center for Medium-Range Weather Forecasts (ECMWF) ERA-40 Reanalysis is used as the first-guess from 1987 to 1998. The ECMWF Operational analysis is used from January 1999 onward. All wind observations and analysis fields are referenced to a height of 10 meters. The ERA-40 can be obtained from the Computation and Information Systems Laboratory (CISL) at the National Center for Atmospheric Research (NCAR): http://rda.ucar.edu/datasets/ds117.0/. The ECMWF Operational analysis can also be obtained from CISL at NCAR: http://rda.ucar.edu/datasets/ds111.1/. Three products are distributed to complete the CCMP dataset series.

VIIRS is a multi-disciplinary instrument that is also being flown on the Joint Polar Satellite System (JPSS) series of spacecraft, of which NOAA-20 is the first. JPSS is a multi-agency program that consolidates the polar orbiting spacecraft of NASA and the National Oceanic and Atmospheric Administration (NOAA). Suomi-NPP is the initial spacecraft in this series, and VIIRS is the successor to MODIS for Earth science data. VIIRS has 22 spectral bands ranging from 412 nm to 12 micron . There are 16 moderate-resolution bands (750m at nadir), 5 image-resolution bands (375 m), and one day-night band (DNB). VIIRS uses on-board pixel aggregation to reduce the growth in size of pixels away from nadir. Two SST products are contained in these files. The first is a skin SST produced separately for day and night observations, derived from the long wave IR 11 and 12 micron wavelength channels, using a modified nonlinear SST algorithm intended to provide continuity of SST products from heritage and current NASA sensors. At night, a second triple channel SST product is generated using the 3.7 , 11 and 12 micron IR channels, identified as SST_triple. Due to the sun glint in the 3.7 micron SST_triple can only be used at night. VIIRS L2P SST data have a 750 spatial resolution at nadir and are stored in ~288 five minute granules per day. Full global coverage is obtained each day. The production of VIIRS NASA L2P SST files is part of the Group for High Resolution Sea Surface Temperature (GHRSST) project and is a joint collaboration between the NASA Jet Propulsion Laboratory (JPL), the NASA Ocean Biology Processing Group (OBPG), and the Rosenstiel School of Marine and Atmospheric Science (RSMAS). Researchers at RSMAS were responsible for sea surface temperature algorithm development, error statistics and quality flagging, while the OBPG, as the NASA ground data system, is responsible for the production of VIIRS ocean products. JPL acquires VIIRS ocean granules from the OBPG and reformats them to the GHRSST L2P netCDF specification with complete metadata and is the official Physical Oceanography Data Archive (PO.DAAC) for SST. In mid-August, 2018, the RSMAS involvement in the VIIRS SST project ceased, and the subsequent fields are not maintained.The R2016.2 supersedes the previous v2016.0 datasets which can be found at https://doi.org/10.5067/GHVRS-2PN16"@en ; "None"@en ; "EARTH SCIENCE"@en ; "2020-09-16"^^xsd:date ; "Dataset Creation via Metadata Tool"@en ; "https://podaac.jpl.nasa.gov/" ; "English"@en ; "JPL/OBPG/RSMAS"@en ; "Jet Propulsion Laboratory"@en ; "2020-02-28"^^xsd:date ; "Jet Propulsion Laboratory, CA, USA"@en ; "GHRSST Level 2P Global Skin Sea Surface Temperature from VIIRS produced by JPL"@en ; "VIIRS L2P swath SST data set"@en ; "180.0"^^xsd:float ; "podaac@podaac.jpl.nasa.gov"@en ; "PODAAC-GHVRS-2PJ62" ; "GHRSST Level 2P Global Sea Surface Skin Temperature from the Visible and Infrared Imager/Radiometer Suite (VIIRS) on the Suomi-NPP satellite (GDS2)"@en ; ""@en ; "Oceans"@en , "Geoscientific Information"@en ; "2019-11-04"^^xsd:date ; ""@en ; "Geographic Region"@en ; "Global"@en ; "Suomi National Polar-orbiting Partnership"@en , ""@en , "Visible Infrared Imaging Radiometer Suite"@en , "Group for High Resolution Sea Surface Temperature"@en ; "CEOS IDN DIF"@en ; "9.8"^^xsd:float ; "90.0"^^xsd:float ; "Information on the the VIIRS SST algorithm can be found in the following documents: http://www.star.nesdis.noaa.gov/jpss/documents/ATBD/D0001-M01-S01-010_JPSS_ATBD_VIIRS-SST_A.pdf" ; "Jet Propulsion Laboratory"@en ; "Data Center Contact"@en ; "SUOMI-NPP"@en , "VIIRS"@en , "USA/NASA"@en , ""@en , "GHRSST"@en ; "-90.0"^^xsd:float ; "2011-11-21"^^xsd:date ; "OCEAN TEMPERATURE"@en ; "OCEANS"@en ; "None"@en ; "SEA SURFACE TEMPERATURE"@en ; "2016.2"^^xsd:float ; "-180.0"^^xsd:float . a owl:DatatypeProperty . a base: ; owl:versionInfo "2020-09-16T19:36:14.541Z" , "2020-09-16T19:36:14.591Z" ; "This dataset contains the Version 1.0 CYGNSS Level 2 Ocean Surface Heat Flux Science Data Record, which provides the time-tagged and geolocated ocean surface heat flux parameters with 25x25 kilometer footprint resolution from the Delay Doppler Mapping Instrument (DDMI) aboard the CYGNSS satellite constellation. The reported sample locations are determined by the specular points corresponding to the Delay Doppler Maps (DDMs). Only one netCDF-4 data file is produced each day (each file containing data from a combination of up to 8 unique CYGNSS spacecraft) with a latency of approximately 1 to 2 months from the last recorded measurement time. Version 1.0 represents the first release. The Cyclone Global Navigation Satellite System (CYGNSS), launched on 15 December 2016, is a NASA Earth System Science Pathfinder Mission that was launched with the purpose to collect the first frequent space-based measurements of surface wind speeds in the inner core of tropical cyclones. Made up of a constellation of eight micro-satellites, the CYGNSS observatories provide nearly gap-free Earth coverage with a mean (i.e., average) revisit time of seven hours and a median revisit time of three hours. The 35 degree orbital inclination allows CYGNSS to measure ocean surface winds between approximately 38 degrees North and 38 degrees South latitude using an innovative combination of all-weather performance Global Positioning System (GPS) L-band ocean surface reflectometry to penetrate the clouds and heavy precipitation. The Coupled Ocean-Atmosphere Response Experiment (COARE) algorithm is what is used in this dataset to estimate the latent and sensible heat fluxes and their respective transfer coefficients. While COARE's initial intentions were for low to moderate wind speeds, the version used for this product, COARE 3.5, has been verified with direct in situ flux measurements for wind speeds up to 25 m/s. As CYGNSS does not provide air/sea temperature, humidity, surface pressure or density, the producer of this dataset obtains these values from the NASA Modern-Era Retrospective Analysis for Research and Applications Version 2 (MERRA-2), which uses data assimilation to combine all available in situ and satellite observation data with an initial estimate of the atmospheric state, provided by a global atmospheric model. Since the MERRA-2 data is only updated on monthly intervals, this corresponding heat flux dataset is likewise updated on a monthly interval to reflect the latest data available from MERRA-2, thus accounting for measurement latency, with respect to CYGNSS observables, ranging from 1 to 2 months. The data from this release compares well with in situ buoy data, including: Kuroshio Extension Observatory (KEO), National Data Buoy Center (NDBC), Ocean Sustained Interdisciplinary Time-series Environment observation System (OceanSITES), Prediction and Research Moored Array in the Tropical Atlantic (PIRATA), Research Moored Array for African-Asian-Australian Monsoon Analysis and Prediction (RAMA), and the Tropical Atmosphere Ocean (TAO) array. As this marks only the first data release, future work is expected to provide comparisons and validation with various field campaigns (e.g., PISTON, CAMP2Ex) as well as more buoy data, especially at higher flux estimates."@en ; "NONE"@en ; "EARTH SCIENCE"@en ; "2020-09-16"^^xsd:date ; "Dataset Creation via Metadata Tool"@en ; "https://podaac.jpl.nasa.gov/" ; "English"@en ; "CYGNSS"@en ; "PO.DAAC"@en ; "2019-08-11"^^xsd:date ; "PO.DAAC"@en ; "CYGNSS Level 2 Ocean Surface Heat Flux Science Data Record"@en ; "CYGNSS Level 2 Ocean Surface Heat Flux Science Data Record Version 1.0"@en ; "360.0"^^xsd:float ; "podaac@podaac.jpl.nasa.gov"@en ; "PODAAC-CYGNS-L2H10" ; "CYGNSS Level 2 Ocean Surface Heat Flux Science Data Record Version 1.0"@en ; ""@en ; "Geoscientific Information"@en , "Oceans"@en ; "2019-07-31"^^xsd:date ; ""@en ; "Geographic Region"@en ; "Global"@en ; ""@en , "Cyclone Global Navigation Satellite System"@en , "Delay Doppler Mapping Instrument"@en ; "CEOS IDN DIF"@en ; "9.8"^^xsd:float ; "40.0"^^xsd:float ; "http://clasp-research.engin.umich.edu/missions/cygnss/" ; "NASA/ESSP/UMICH/CYGNSS"@en ; "Data Center Contact"@en ; "USA/NASA"@en , "CYGNSS"@en , "DDMI"@en , ""@en ; "40.0"^^xsd:float ; "2017-03-18"^^xsd:date ; "OCEAN HEAT BUDGET"@en ; "OCEANS"@en ; "NONE"@en ; "HEAT FLUX"@en ; "1.0"^^xsd:float ; "0.0"^^xsd:float . a base: ; owl:versionInfo "2020-09-16T19:36:14.559Z" , "2020-09-16T19:36:14.600Z" ; "Day and night spatially gridded global NASA skin sea surface temperature (SST) products from the Moderate-resolution Imaging Spectroradiometer (MODIS) onboard the Terra satellite.

Terra was launched by NASA on December 18, 1999, into a sun synchronous, polar orbit with a daylight descending node at 10:30 am, to study the global dynamics of the Earth atmosphere, land and oceans. The MODIS captures data in 36 spectral bands at a variety of spatial resolutions. Two SST products can be present in these files. The first is a skin SST produced for both day and night observations, derived from the long wave IR 11 and 12 micron wavelength channels, using a modified nonlinear SST algorithm intended to provide continuity with SST derived from heritage and current NASA sensors. At night, a second SST product is produced using the mid-infrared 3.95 and 4.05 micron channels which are unique to MODIS; the SST derived from these measurements is identified as SST4. The SST4 product has lower uncertainty, but due to sun glint can only be produced at night. To generate the L3 products the L2 pixels are binned into an integerized sinusoidal area grid (ISEAG) and mapped into an equidistant cylindrical (also known as Platte Carre) projection.

The CCMP data set includes cross-calibrated satellite winds derived from SSM/I, SSMIS, AMSR-E, TRMM TMI, QuikSCAT, SeaWinds, WindSat and other satellite instruments as they become available from REMSS.

Focused around a central mooring located near 10N,125W, the objective of SPURS-2 was to study the dynamics of the rainfall-dominated surface ocean at the western edge of the eastern Pacific fresh pool subject to high seasonal variability and strong zonal flows associated with the North Equatorial Current and Countercurrent. Underway physical data from 6 cruises undertaken by the schooner Lady Amber during the SPURS-2 field campaign include along-track meteorological, salinity snake and fixed-hull CTD measurements at 1m and 2 m intake depths.

CAP Level 3 standard mapped image products contain gridded 1 degree spatial resolution salinity and wind speed data averaged over 7 day and monthly time scales. This particular dataset is the monthly wind speed V5.0 Aquarius CAP product. CAP is a P.I. produced dataset developed and provided by JPL. The CAP algorithm utilizes data from both the onboard radiometer and scatterometer to simultaneously retrieve salinity, wind speed and direction by minimizing the sum of squared differences between model and observations. The main improvements in CAP V5.0 relative to the previous version include: updates to the Geophysical Model Functions to 4th order harmonics with the inclusion of sea surface temperature (SST) and stability at air-sea interface effects; use of the Canadian Meteorological Center (CMC) SST product as the new source ancillary sea surface temperature data in place of NOAA OI SST. The Aquarius instrument is onboard the AQUARIUS/SAC-D satellite, a collaborative effort between NASA and the Argentinian Space Agency Comision Nacional de Actividades Espaciales (CONAE). The instrument consists of three radiometers in push broom alignment at incidence angles of 29, 38, and 46 degrees incidence angles relative to the shadow side of the orbit. Footprints for the beams are: 76 km (along-track) x 94 km (cross-track), 84 km x 120 km and 96km x 156 km, yielding a total cross-track swath of 370 km.

Sigma-0) from the L1B dataset. RapidScat is a Ku-band dual beam circular rotating scatterometer retaining much of the same hardware and functionality of QuikSCAT, with exception of the antenna sub-system and digital interface to the International Space Station (ISS) Columbus module, which is where RapidScat is mounted. The NASA mission is officially referred to as ISS-RapidScat. Unlike QuikSCAT, ISS-RapidScat is not in sun-synchronous orbit, and flies at roughly half the altitude with a low inclination angle that restricts data coverage to the tropics and mid-latitude regions; the extent of latitudinal coverage stretches from approximately 61 degrees North to 61 degrees South. Furthermore, there is no consistent local time of day retrieval. This dataset is provided in a netCDF-3 file format that follows the netCDF-4 classic model (i.e., generated by the netCDF-4 API) and made available via PO.DAAC Drive and OPeNDAP. For data access, please click on the \"Data Access\" tab above. This climate quality data set differs from the nominal \"slice\" L2B dataset as follows: 1) it uses full antenna footprint measurements (~20-km) without subdividing by range (~7-km) and 2) the absolute calibration has been modified for the two different low signal-to-noise ratio (SNR) mode data sets: LowSNR1 14 August 2015 to 18 September 2015; LowSNR2 6 October 2015 to 7 February 2016. The above enhancements allow this dataset to provide consistent calibration across all SNR states.

Level-3C SST, in the NetCDF format recommended by Group for High Resolution Sea Surface Temperature (GHRSST), is identical to Level-2P GHRSST products, 3 refers to gridded products and C to the fact that hourly products result from compositing 15 minutes (MSG) or 30 minutes (GOES-E) data.The European Organization for the Exploitation of Meteorological Satellites (EUMETSAT), OSI SAF is producing SST products in near real time from MSG/SEVIRI. SEVIRI level 1.5 data are acquired at Meteo-France/Centre de Meteorologie Spatiale (CMS) through the EUMETSAT/EUMETCAST system. SST is retrieved from the SEVIRI infrared channels (10.8 and 12.0 micrometer) using a multispectral algorithm. Atmospheric profiles of water vapor and temperature from a numerical weather prediction model, together with a radiatiave transfer model, are used to correct the multispectral algorithm for regional and seasonal biases due to changing atmospheric conditions. Every 15 minutes slot is processed at full satellite resolution. The operational products are then produced by remapping over a 0.05-degree regular grid (60S-60N and 135W-15W) SST fields obtained by aggregating all 15-minute SST data available in one-hour time, and the priority being given to the value the closest in time to the product nominal hour.

Version 1.3 is intended as a replacement and continuation of the Version 1.1 and 1.2 data forward from orbital revolution number 7873, corresponding to 11 February 2016; on 11 Feb 2016, RapidScat entered it's 3rd low signal to noise ratio (SNR) state and the initial calibration of low SNR 3 was preliminary during the Version 1.2 release. The fundamental difference between Version 1.3 and the previous Version 1.2 datasets is that the L1B sigma-0 has been re-calibrated during the periods of low SNR states 3 and 4 using re-pointed QuikSCAT data. Due to the circular scan of the SeaWinds instrument the expected number of Sigma-0 cells per WVC is not constant. To minimize the L2A data volume, the Sigma-0 cell data are stored as \"lists\" for each WVC row, with each list indexed by a \"cell_index\" array to indicate the cross-track WVC membership of the data. Each cell is then checked for land or ice and flagged accordingly. Attenuation corrections for each Sigma-0 measurement are also provided. Data are provided in single-orbit files in HDF-4 format. RapidScat is a Ku-band dual beam circular rotating scatterometer retaining much of the same hardware and functionality of QuikSCAT, with exception of the antenna sub-system and digital interface to the International Space Station (ISS) Columbus module, which is where RapidScat is mounted. The NASA mission is officially referred to as ISS-RapidScat. Unlike QuikSCAT, ISS-RapidScat is not in sun-synchronous orbit, and flies at roughly half the altitude with a low inclination angle that restricts data coverage to the tropics and mid-latitude regions; the extent of latitudinal coverage stretches from approximately 61 degrees North to 61 degrees South.

The retrievals are provided on a non-uniform grid within the swath at 12.5 km pixel resolution. Higher resolution is achieved through a slice composite technique in which high resolution slice measurements from L1B data are composited into a 12.5 km wind vector cell. Each L2B file corresponds to a specific orbital revolution (rev) number, which begins at the southernmost point of the ascending orbit. This is an official dataset produced by the NASA QuikSCAT Project through the SeaWinds Processing and Analysis Center (SeaPAC). Version 4.0 processing begins with the same L1B (time-ordered backscatter) data as used in the previous Version 3.1 processing. The new version has three important improvements over the previous version 3.1. First, a sea-surface temperature (SST) dependent geophysical model function (GMF) developed by Lucrezia Ricciardulli of Remote Sensing Systems is used in wind retrieval in order to fix persistent speed biases in Ku-band data over cold ocean. Second, near coastal winds are retrieved using the Land Contamination Ratio with Expected Sigma-0 (LCRES) technique which retrieves winds significantly closer to the coast than has been done before. Third, flagging is simplified and extra flags are provided. All of the legacy quality flags are preserved with the same meaning. A new single bit wind_retrieval_likely_corrupted_flag is established for conditions in which approximately 3% (or greater) of the data comprising a wind vector cell (WVC) exhibits suboptimal performance due to rain, ice, or a few other rare anomalous cases. Another bit wind_retrieval_possibly_corrupted_flag is established for conditions in which approximately 15% of the data comprising a WVC near rain, ice, or a coastal boundary is thought to be high quality but may not match up well with numerical wind models due to either remaining rain/ice/land contamination or variability in the winds near ice, rain, and coasts that are not reflected in the numerical weather prediction (NWP) matchups. In addition to these two new bits, copious quality information is provided in the flags and eflags variables to allow users to tailor flags to meet their own needs.

The Advanced Himawari Imager (AHI; largely identical to GOES-R/ABI) is a 16 channel sensor, of which five (3.9, 8.4, 10.3, 11.2, and 12.3 um) are suitable for SST. Accurate sensor calibration, image navigation and (co)registration, high spectral fidelity, and sophisticated pre-processing (geo-rectification, radiance equalization, and mapping) offer vastly enhanced capabilities for SST retrievals, over the heritage GOES-I/P and MTSAT-2 Imagers. From altitude 35,800km, H08/AHI maps SST in a Full Disk (FD) area from 80E-160W and 60S-60N, with spatial resolution 2km at nadir to 15km at view zenith angle 67-deg, with a 10-min temporal sampling. The AHI L2P (swath) SST product is derived at the native sensor resolution using NOAA's Advanced Clear-Sky Processor for Ocean (ACSPO) system. ACSPO processes every 10-min FD data, identifies good quality ocean pixels (Petrenko et al., 2010) and derives SST using the four-band (8.4, 10.3, 11.2 and 12.3um) Non-Linear SST (NLSST) regression algorithm (Petrenko et al., 2014), trained against in situ SSTs from drifting and tropical mooring buoys in the NOAA iQuam system (Xu and Ignatov, 2014). The 10-min data are subsequently collated in time, to produce 1-hr L2P product, with improved coverage, and reduced cloud leakages and image noise. The collated L2P reports SSTs and brightness temperatures (BTs) in clear-sky water pixels (defined as ocean, sea, lake or river), and fill values elsewhere. All pixels with valid SSTs are recommended for use. ACSPO files also include sun-sensor geometry, l2p_flags (day/night, land, ice, twilight, and glint flags), and NCEP wind speed. The L2P is reported in NetCDF4 GHRSST Data Specification version 2 (GDS2) format, 24 granules per day, with a total data volume 0.6GB/day. Pixel earth locations are not reported in the granules, as they remain unchanged from granule to granule. Those can be obtained using a flat lat/lon file or a Python script available at https://podaac-tools.jpl.nasa.gov/drive/files/allData/ghrsst/data/GDS2/L2P/H08/STAR/nav. Per GDS2 specifications, two additional Sensor-Specific Error Statistics layers (SSES bias and standard deviation) are reported in each pixel (Petrenko et al., 2016). The H08 AHI SSTs and BTs are continuously validated against in situ data in SQUAM (Dash et al, 2010), and RTM simulation in MICROS (Liang and Ignatov, 2011).

It is based on the Combined Active-Passive (CAP) retrieval algorithm developed at JPL originally in the context of Aquarius/SAC-D and now extended to SMAP. Improvements with V4.3 include: 1) New residual TB calibration which removes the ascending/descending bias issue observed for version 4.3; 2) Slightly modified criteria for aggregation from L2B to L3 based on TB for V-pol minus TB for H-pol. The JPL SMAP-SSS L2B CAP product includes data for a range of parameters: derived SMAP sea surface salinity, SSS uncertainty and wind speed/direction data for extreme winds, brightness temperatures for each radiometer polarization, ancillary reference surface salinity, ice concentration, wind and wave height data, quality flags, and navigation data. Each data file covers one 98-minute orbit (15 files per day). Data begins on April 1,2015 and is ongoing, with a 3 day latency in processing and availability. Observations are global in extent and provided at 25km swath grid with an approximate spatial resolution of 60 km. The SMAP satellite is in a near-polar orbit at an inclination of 98 degrees and an altitude of 685 km. It has an ascending node time of 6 pm and is sun-synchronous. With its 1000km swath, SMAP achieves global coverage in approximately 3 days, but has an exact orbit repeat cycle of 8 days. On board Instruments include a highly sensitive L-band radiometer operating at 1.41GHz and an L-band 1.26GHz radar sensor providing complementary active and passive sensing capabilities.

The drone is autonomous in that it may be guided remotely from land while being completely wind driven. The saildrone ATOMIC (Atlantic Tradewind Ocean-Atmosphere Mesoscale Interaction Campaign) campaign involved the deployment of a fleet of saildrones, jointly funded by NASA and NOAA, in the Atlantic waters offshore of Barbados over a 45 day period from 17 January to 2 March 2020. The goal was to understand the Ocean-Atmosphere interaction particularly over the mesoscale ocean eddies in that region. The saildrones were equipped with a suite of instruments that included a CTD, IR pyrometer, fluorometer, dissolved oxygen sensor, anemometer, barometer, and Acoustic Doppler Current Profiler (ADCP). Additionally, four temperature data loggers were positioned vertically along hull to provide further information on thermal variability near the ocean surface. This Saildrone ATOMIC dataset is comprised of two data files for each of the three NASA-funded saildrones deployed, one for the surface observations and one for the ADCP measuements. The surface data files contain saildrone platform telemetry and near-surface observational data (air temperature, sea surface skin and bulk temperatures, salinity, oxygen and chlorophyll-a concentrations, barometric pressure, wind speed and direction) spanning the entire cruise at 1 minute temporal resolution.

This Level 2B dataset is produced by the Jet Propulsion Laboratory (JPL) QuikSCAT Project in cooperation with ISRO. The retrievals are provided on a non-uniform grid within the swath at 12.5 km pixel resolution. This resolution is achieved through a slice composite technique in which high resolution slice measurements from L1B data are composited into a 12.5 km wind vector cell. This newest version contains an improved geophysical model function (GMF), known as QSCAT12, consistent with the Remote Sensing Systems Ku2011 GMF, and an improved rain detection and flagging algorithm; these algorithms are consistent with the latest reprocessed version 3 QuikSCAT L2B dataset. Each L2B file corresponds to a specific orbital revolution (rev) number, which begins at the southernmost point of the ascending orbit. As a Ku-band dual pencil-beam rotating scatterometer, OSCAT design specs bear a strong resemblence of the Ku-band SeaWinds scatterometers on QuikSCAT and Midori-II (ADEOS-II). The primary difference between OSCAT and SeaWinds is the ~4 degree increase in the OSCAT incidence angle, which acts as an offset to the relatively lower altitude of Oceansat-2 to help provide a nearly identical swath width to SeaWinds. In the early phase of cal/val, the JPL QuikSCAT Project identified several problems, most of which have been corrected in this latest L2B version. This dataset release is expected to have an accuracy similar to that of the version 3 L2B QuikSCAT product, with minor caveats, all of which are described by Jaruwatanadilok et al.

The project involves two field campaigns and a series of cruises in regions of the Atlantic and Pacific Oceans exhibiting salinity extremes. SPURS employs a suite of state-of-the-art in-situ sampling technologies that, combined with remotely sensed salinity fields from the Aquarius/SAC-D and SMOS satellites, provide a detailed characterization of salinity structure over a continuum of spatio-temporal scales. The SPURS-1 campaign involved a series of 5 cruises during 2012 - 2013 seeking to characterize the salinity structure and balance in a high salinity, high evaporation, and low rainfall region of the subtropical North Atlantic. It aims to resolve processes responsible for maintaining the subtropical surface salinity maximum in this region and within a 900 x 800-mile square study area centered at 25N, 38W. A Waveglider is an autonomous platform propelled by the conversion of ocean wave energy into forward thrust and employing solar panels to power instrumentation. During SPURS-1, three wavegliders (ASL2, ASL3 and ASL4) were deployed from the Knorr in September 2012, redeployed in April 2013 (ASL22, ASL32 and ASL42) with final recovery in September. Waveglider trajectories followed a square loop or butterfly pattern around the central SPURS mooring. Sensors included a CTD at the near-surface and another at 6 m depth, a surface current meter, air temperature, atmospheric pressure and wind speed sensors providing continuous along-track observations. NetCDF waveglider data files here contain hour averaged, georeferenced trajectory data for those parameters and depths."@en ; "NONE"@en ; "EARTH SCIENCE"@en ; "2020-09-16"^^xsd:date ; "Dataset Creation via Metadata Tool"@en ; "https://podaac.jpl.nasa.gov/" ; "English"@en ; "SPURS PROJECT, Fred Bingham"@en ; "SPURS Data Management PI, Fred Bingham"@en ; "2015-05-11"^^xsd:date ; "Department of Physics and Physical Oceanography, University on North Carolina, Wilmington, NC, USA"@en ; "Waveglider data for the SPURS-1 N.

Focused around a central mooring located near 10N,125W, the objective of SPURS-2 was to study the dynamics of the rainfall-dominated surface ocean at the western edge of the eastern Pacific fresh pool subject to high seasonal variability and strong zonal flows associated with the North Equatorial Current and Countercurrent.

The first is a skin SST produced for both day and night observations, derived from the long wave IR 11 and 12 micron wavelength channels, using a modified nonlinear SST algorithm intended to provide continuity with SST derived from heritage and current NASA sensors. At night, a second SST product is produced using the mid-infrared 3.95 and 4.05 micron channels which are unique to MODIS; the SST derived from these measurements is identified as SST4. The SST4 product has lower uncertainty, but due to sun glint can only be produced at night.

This dataset contains estimates of static field geopotential of the Earth, derived from the Gravity Recovery and Climate Experiment (GRACE) mission measurements, produced by the German Research Centre for Geosciences (GFZ). The data are in spherical harmonics averaged over approximately a month. The primary objective of the GRACE mission is to obtain accurate estimates of the mean and time-variable components of the gravity field variations. This objective is achieved by making continuous measurements of the change in distance between twin spacecraft, co-orbiting in about 500 km altitude, near circular, polar orbit, spaced approximately 200 km apart, using a microwave ranging system. In addition to these range change, the non-gravitional forces are measured on each satellite using a high accuracy electrostatic, room-temperature accelerometer. The satellite orientation and position (and timing) are precisely measured using twin star cameras and a GPS receiver, respectively. Spatial and temporal variations in the gravity field affect the orbits (or trajectories) of the twin spacecraft differently. These differences are manifested as changes in the distance between the spacecraft, as they orbit the Earth. This change in distance is reflected in the time-of-flight of microwave signals transmitted and received nearly simultaneously between the two spacecraft. The change in this time of fight is continuously measured by tracking the phase of the microwave carrier signals. The so called dual-one-way range change measurements can be reconstructed from these phase measurements. This range change (or its numerically derived derivatives), along with other mission and ancillary data, is subsequently analyzed to extract the parameters of an Earth gravity field model."@en ; "none"@en ; "EARTH SCIENCE"@en ; "2020-09-16"^^xsd:date ; "Dataset Creation via Metadata Tool"@en ; "https://podaac.jpl.nasa.gov/" ; "English"@en ; "GRACE"@en ; "GFZ"@en ; "2018-08-31"^^xsd:date ; "JPL"@en ; "GRACE Monthly Geopotential Spherical Harmonic Coefficients GFZ (GSM)"@en ; "GRACE_GSM_L2_GRAV_GFZ_RL06"@en ; "180.0"^^xsd:float ; "podaac@podaac.jpl.nasa.gov"@en ; "PODAAC-GRGSM-20G06" ; "GRACE FIELD GEOPOTENTIAL COEFFICIENTS GFZ RELEASE 6.0"@en ; ""@en ; "Geoscientific Information"@en , "Oceans"@en ; "2018-08-06"^^xsd:date ; ""@en ; "Geographic Region"@en ; "Global"@en ; "GRACE SuperSTAR Accelerometer"@en , "Star Camera Assembly"@en , "GRACE K-Band Ranging System"@en , "Gravity Recovery and Climate Experiment"@en , ""@en ; "CEOS IDN DIF"@en ; "9.8"^^xsd:float ; "88.0"^^xsd:float ; "https://podaac-tools.jpl.nasa.gov/drive/files/allData/grace/docs/" ; "GRACE/GFZ"@en ; "Data Center Contact"@en ; "USA/NASA"@en , "GRACE"@en , ""@en , "GRACE ACC"@en , "GRACE KBR"@en , "GRACE SCA"@en ; "-88.0"^^xsd:float ; "2002-04-05"^^xsd:date ; "2017-07-01"^^xsd:date ; "GRAVITY/GRAVITATIONAL FIELD"@en , "OCEAN PRESSURE"@en ; "SOLID EARTH"@en , "OCEANS"@en ; "none"@en ; "WATER PRESSURE"@en , "GRAVITY"@en ; "6.0"^^xsd:float ; "-180.0"^^xsd:float . a owl:DatatypeProperty . a base: ; owl:versionInfo "2020-09-16T19:36:14.280Z" ; "The NASA Scatterometer (NSCAT) Level 2.5 high-resolution merged ocean wind vectors and sigma-0 in 25 km wind vector cell (WVC) swaths contain daily data from ascending and descending passes.

The AVHRR is a space-borne scanning sensor on the National Oceanic and Atmospheric Administration (NOAA) family of Polar Orbiting Environmental Satellites (POES) having a operational legacy that traces back to the Television Infrared Observation Satellite-N (TIROS-N) launched in 1978. AVHRR instruments measure the radiance of the Earth in 5 (or 6) relatively wide spectral bands. The first two are centered around the red (0.6 micrometer) and near-infrared (0.9 micrometer) regions, the third one is located around 3.5 micrometer, and the last two sample the emitted thermal radiation, around 11 and 12 micrometers, respectively. The legacy 5 band instrument is known as AVHRR/2 while the more recent version, the AVHRR/3 (first carried on the NOAA-15 platform), acquires data in a 6th channel located at 1.6 micrometer. Typically the 11 and 12 micron channels are used to derive SST sometimes in combination with the 3.5 micron channel. The NOAA platforms are sun synchronous generally viewing the same earth location twice a day (latitude dependent) due to the relatively large AVHRR swath of approximately 2400 km. The highest ground resolution that can be obtained from the current AVHRR instruments is 1.1 km at nadir. AVHRR data are acquired in three formats: High Resolution Picture Transmission (HRPT), Local Area Coverage (LAC), and Global Area Coverage (GAC). HRPT data are full resolution image data transmitted to a ground stations as they are collected. LAC are also full resolution data, but the acquisition is prescheduled and recorded with an on-board tape recorder for subsequent transmission during a station overpass. This particular dataset is produced from GAC data that are derived from an on-board sample averaging of the full resolution global AVHRR data. Four out of every five samples along the scan line are used to compute on average value and the data from only every third scan line are processed, yielding an effective 4 km resolution at nadir. Further binning and averaging of these pixels results in a final dataset resolution of 8.8 km."@en ; "None"@en ; "EARTH SCIENCE"@en ; "2020-09-16"^^xsd:date ; "REPAIRED META_HISTORY ENTRY"@en ; "https://podaac.jpl.nasa.gov/" , "http://www.nodc.noaa.gov/" ; "English"@en ; "Naval Oceanographic Office"@en ; "Naval Oceanographic Office"@en ; "2009-09-27"^^xsd:date ; "Stennis Space Center, MS, USA"@en ; "GHRSST Level 2P Global Bulk Sea Surface Temperature from the Advanced Very High Resolution Radiometer (AVHRR) on the NOAA-19 satellite produced by NAVO"@en ; "N-19 AVHRR GAC L2P swath SST data set"@en ; "180.0"^^xsd:float ; "NODC.Services@noaa.gov"@en , "podaac@podaac.jpl.nasa.gov"@en ; "PODAAC-GH19G-2PN01" ; "GHRSST Level 2P Global Bulk Sea Surface Temperature from the Advanced Very High Resolution Radiometer (AVHRR) on the NOAA-19 satellite produced by NAVO"@en ; ""@en ; "Geoscientific Information"@en , "Oceans"@en ; "2017-04-28"^^xsd:date ; ""@en ; "Geographic Region"@en ; "Global"@en ; "National Oceanic & Atmospheric Administration-20"@en , ""@en , "Group for High Resolution Sea Surface Temperature"@en , "Advanced Very High Resolution Radiometer-3"@en ; "CEOS IDN DIF"@en ; "9.8"^^xsd:float ; "80.0"^^xsd:float ; "" ; "Naval Oceanographic Office"@en ; "Data Center Contact"@en ; "AVHRR-3"@en , ""@en , "GHRSST"@en , "USA/NASA"@en , "NOAA-20"@en ; "-70.0"^^xsd:float ; "2009-10-05"^^xsd:date ; "2015-02-17"^^xsd:date ; "OCEAN TEMPERATURE"@en ; "OCEANS"@en ; "None"@en ; "SEA SURFACE TEMPERATURE"@en ; "1.0"^^xsd:float ; "-180.0"^^xsd:float . a base: ; owl:versionInfo "2020-09-16T19:36:14.380Z" ; "The Moderate-resolution Imaging Spectroradiometer (MODIS) is a scientific instrument (radiometer) on board the NASA Terra and Aqua satellite platforms, launched in 1999 and 2002 respectively to study global dynamics of the Earths atmosphere, land, ice and oceans.

For 'egg' measurements, the full antenna/processing spatial response is used while a simplified spatial response function in which the spatial response is assumed to be 1 over the footprint and 0 elsewhere is used for 'slice' measurements. The SIR algorithm with 'eggs' makes images of sigma-0 at the measurement incidence angle at 4.5 km pixel resolution. The effective resolution varies depending on region and sampling conditions but is estimated to be 8-10 km in most areas. The SIRF algorithm with 'slices' makes images at 2.225 km pixel resolution with an estimated effective resolution of 6-8 km. It is worth noting that 'slice' measurements are inherently noisier than 'egg' measurements. This dataset has been pre-subsetted for the following regions: Alaska, Amazonia, Antarctica, Arctic, Australia, Bering Strait, Greenland, Central America, East China Sea, Sea of Japan, Europe, Indonesia, Northern Africa, North America, Southern Africa, South America, Southern Asia, and Siberia. Non-enhanced fields are also provided at lower resolution in a 'GRD' gridded format that does not utilize SIR processing; 'GRD' fields are provided at 11.125 km and 22.25 km pixel resolution for slices and eggs, respectively. In addition to Sigma-0, various statistical parameters are provided for added guidance, including but not limited to: standard deviation of incidence angle, mean incidence angle, measurement counts, pixel time, mean reconstruction error, and standard deviation of the reconstructed sigma-0. Sigma-0 fields are available for specific ascending/descending nodes, local time of day, or as a daily average. SIR-formatted land mask files (containing 0 for ocean and 1 for land) are available for each standard region. SIR-formatted files containing the gridded latitude and longitude pixel locations within each region are also available.

The SMAP-SSS L2C product includes data for a range of parameters: derived sea surface salinity (SSS) with SSS-uncertainty, brightness temperatures for each radiometer polarization, antenna temperatures, collocated wind speed, data and ancillary reference surface salinity data from HYCOM, rain rate, quality flags, and navigation data. Each data file covers one 98-minute orbit (15 files per day). Data begins on April 1,2015 and is ongoing. Observations are global in extent and provided at a 0.25 degree x 0.25 degree grid with an approximate spatial feature resolution of 40KM. Note that while a SSS 40KM variable is also included in the product, for most open ocean applications, the default SSS variable (70KM) is best used as they are significantly less noisy than the 40KM data.The SMAP satellite is in a near-polar orbit at an inclination of 98 degrees and an altitude of 685 km. It has an ascending node time of 6 pm and is sun-synchronous. With its 1000km swath, SMAP achieves global coverage in approximately 3 days, but has an exact orbit repeat cycle of 8 days.

The eight hour interval at each LTOD reference of morning vs. evening corresponds to the natural boundaries of time separation within the data at polar latitudes. Hence, morning and evening are used as approximations for the LTOD reference, where the actual LTOD may vary within the respective 8 hour interval. This dataset is generated using a Scatterometer Image Reconstruction (SIR) technique developed by Dr. David Long at Brigham Young University (BYU); the processed files are therefore known as SIR files. These SIR files were also used to generate a complimentary dataset of GIF images meant for browse purposes only and is available here: http://podaac.jpl.nasa.gov/dataset/SEAWINDS_BYU_L3_OW_SIGMA0_ANTARCTIC_POLAR-STEREOGRAPHIC_BROWSE_IMAGES_LTOD. The SeaWinds scatterometer scans at two nominal incidence angles, 46 degrees and 54.1 degrees, corresponding to the inner and outer beams respectively. The inner beam is horizontally polarized while the outer beam is vertically polarized. The SIR files are separated according to polarization. For example, one SIR file for a particular day and LTOD will contain the gridded average Sigma-0 values for the horizontally polarized L1B retrievals, while the other will contain those from the vertically polarized L1B retrievals.

The drone is autonomous in that it may be guided remotely from land while being completely wind driven. The saildrone Arctic campaign involved the deployment of a fleet of 5 saildrones, jointly funded by NASA and NOAA, from Dutch Harbor, Alaska, within the Bering and Chukchi Seas to the ice edge and back over a 150-day period from 15 May 2019 to 11 October 2019. Scientific objectives include collecting upper ocean temperature profiles with a full suite of ocean measurements, which could lead to significant improvements in modeling of diurnal warming. Additionally, these new data will provide additional Arctic SST observations to benefit SST algorithm development and validation, and collected additional data for studies of air- sea-ice interactions. For the Arctic cruises, saildrones were equipped with a suite of instruments that included a CTD, IR pyrometer, fluorometer, dissolved oxygen sensor, anemometer, barometer, and Acoustic Doppler Current Profiler (ADCP). Additionally, four temperature data loggers were positioned vertically along hull to provide further information on thermal variability near the ocean surface. This Saildrone Arctic dataset is comprised of 3 data files for each of the two NASA-funded saildrones deployed. The one file type contains saildrone platform telemetry and near-surface observational data (air temperature, sea surface skin and bulk temperatures, salinity, oxygen and chlorophyll-a concentrations, barometric pressure, wind speed and direction) spanning the entire cruise at 1 minute temporal resolution. The second file type contains the ADCP current vector data for each of the deployed saildrones that is depth-resolved to 100m at 2m intervals and binned temporally at 1 minute resolution.

These data are provided in a single data file in netCDF format, and can be used for analysis for ocean, ice, and hydrology phenomena. This version of the data employs a Coastal Resolution Improvement (CRI) filter that reduces signal leakage errors across coastlines. The water storage/height anomalies are given in equivalent water thickness units (cm). The solution provided here is derived from solving for monthly gravity field variations in terms of geolocated spherical cap mass concentration functions, rather than global spherical harmonic coefficients. Additionally, realistic geophysical information is introduced during the solution inversion to intrinsically remove correlated error. Thus, these Mascon grids do not need to be destriped or smoothed, like traditional spherical harmonic gravity solutions. The complete Mascon solution consists of 4,551 relatively independent estimates of surface mass change that have been derived using an equal-area 3-degree grid of individual mascons. A subset of these individual mascons span coastlines, and contain mixed land and ocean mass change signals. In a post-processing step, the CRI filter is applied to those mixed land/ocean Mascons to separate land and ocean mass. The land mask used to perform this separation is provided in the same directory as this dataset. Since the individual mascons act as an inherent smoother on the gravity field, a set of optional gain factors (for continental hydrology applications) that can be applied to the solution to study mass change signals at sub-mascon resolution is also provided within the same data directory as the Mascon data. Please refer to the 'Data Access' tab at the top of this page to gain direct access to the Mascon data. For more information, please visit https://grace.jpl.nasa.gov/data/get-data/jpl_global_mascons/.

Aqua was launched by NASA on May 4, 2002, into a sun synchronous, polar orbit with a daylight ascending node at 13:30, formation flying in the A-train with other Earth Observation Satellites (EOS), to study the global dynamics of the Earth atmosphere, land and oceans. MODIS captures data in 36 spectral bands at a variety of spatial resolutions. Two SST products can be present in these files. The first is a skin SST produced for both day and night (NSST) observations, derived from the long wave IR 11 and 12 micron wavelength channels, using a modified nonlinear SST algorithm intended to provide continuity of SST derived from heritage and current NASA sensors. At night, a second SST product is generated using the mid-infrared 3.95 and 4.05 micron wavelength channels which are unique to MODIS; the SST derived from these measurements is identified as SST4. The SST4 product has lower uncertainty, but due to sun glint can only be used at night. To generate the L3 products the L2 pixels are binned into an integerized sinusoidal area grid (ISEAG) and mapped into an equidistant cylindrical (also known as Platte Carre projection. Additional projection detailed can be found at https://oceancolor.gsfc.nasa.gov/docs/format/The NASA MODIS L3 SST data products are generated by the NASA Ocean Biology Processing Group (OBPG) and Peter Minnett and his team at the Rosenstiel School of Marine and Atmospheric Science (RSMAS) are responsible for sea surface temperature algorithm development, error statistics and quality flagging.

It should be noted that these GIF images are meant for browse purposes only and should not be considered science quality. The GIF images are generated from a scientific dataset employing a Scatterometer Image Reconstruction (SIR) technique developed by Dr. David Long at Brigham Young University (BYU); the science quality source dataset containing the SIR files used to generate the GIF images is accessible here: http://podaac.jpl.nasa.gov/dataset/SEAWINDS_BYU_L3_OW_SIGMA0_ANTARCTIC_POLAR-STEREOGRAPHIC_BROWSE_MAPS_LTOD.

CAP Level 3 standard mapped image products contain gridded 1 degree spatial resolution salinity and wind speed data averaged over 7 day and monthly time scales. This particular dataset is the monthly sea surface salinity (SSS) rain corrected V5.0 Aquarius CAP product. CAP is a P.I. produced dataset developed and provided by JPL. The CAP algorithm utilizes data from both the onboard radiometer and scatterometer to simultaneously retrieve salinity, wind speed and direction by minimizing the sum of squared differences between model and observations. The main improvements in CAP V5.0 relative to the previous version include: updates to the Geophysical Model Functions to 4th order harmonics with the inclusion of sea surface temperature (SST) and stability at air-sea interface effects; use of the Canadian Meteorological Center (CMC) SST product as the new source ancillary sea surface temperature data in place of NOAA OI SST. The Aquarius instrument is onboard the AQUARIUS/SAC-D satellite, a collaborative effort between NASA and the Argentinian Space Agency Comision Nacional de Actividades Espaciales (CONAE). The instrument consists of three radiometers in push broom alignment at incidence angles of 29, 38, and 46 degrees incidence angles relative to the shadow side of the orbit. Footprints for the beams are: 76 km (along-track) x 94 km (cross-track), 84 km x 120 km and 96km x 156 km, yielding a total cross-track swath of 370 km. The radiometers measure brightness temperature at 1.413 GHz in their respective horizontal and vertical polarizations (TH and TV).

This dataset contains estimates of the total month-by-month geopotential of the Earth, derived from the Gravity Recovery and Climate Experiment Follow-On (GRACE-FO) mission measurements, produced by the NASA Jet Propulsion Laboratory (JPL). The data are provided in spherical harmonic coefficients, averaged over approximately a month. The primary objective of the GRACE-FO mission is to obtain accurate estimates of the mean and time-variable components of the gravity field and corresponding Earth mass change variations, such as from polar ice sheets and mountain glaciers; total water storage on land (from groundwater changes in deep aquifers to changes in soil moisture and surface water); changes in deep ocean currents; and changes within the solid Earth itself, such as postglacial rebound and the impact of major earthquakes. This objective is achieved by making continuous measurements of the change in distance between twin spacecraft, co-orbiting in about 490 km altitude, near circular, polar orbit, spaced approximately 220+/-50 km apart, using a microwave ranging system. In addition to these inter-satellite range changes, the non-gravitational forces acting on each satellite are measured using a high accuracy electrostatic accelerometer. The satellite orientation and position (and timing) are precisely measured using star cameras (with three heads per satellite) and a GPS receiver. Spatial and temporal variations in the gravity field perturb the orbits (or trajectories) of the twin spacecraft differently. These differences lead to minute changes (on the order of tens of micrometers per second) in the distance between the spacecraft as they orbit the Earth. This change in distance (or range rate) is reflected in the time-of-flight of microwave signals transmitted and received nearly simultaneously between the two spacecraft. The change in this time of fight is continuously measured by tracking the phase of the microwave carrier signals. The so called dual-one-way range change measurements can be reconstructed from these phase measurements. This range change (or its numerically derived derivatives), along with other mission and ancillary data, is subsequently analyzed to extract the geopotential coefficients of an Earth gravity field model, typically on a per-month basis."@en ; "none"@en ; "EARTH SCIENCE"@en ; "2020-09-16"^^xsd:date ; "Dataset Creation via Metadata Tool"@en ; "https://podaac.jpl.nasa.gov/" ; "English"@en ; "GRACE-FO"@en ; "JPL"@en ; "2019-06-10"^^xsd:date ; "JPL"@en ; "GRACE-FO Level-2 Monthly Geopotential Spherical Harmonics JPL"@en ; "GRACEFO_L2_JPL_MONTHLY_0060"@en ; "180.0"^^xsd:float ; "podaac@podaac.jpl.nasa.gov"@en ; "PODAAC-GFL20-MJ060" ; "GRACE-FO Level-2 Monthly Geopotential Spherical Harmonics JPL Release 6.0 (RL06)"@en ; ""@en ; "Geoscientific Information"@en , "Oceans"@en ; "2017-10-04"^^xsd:date ; ""@en ; "Geographic Region"@en ; "Global"@en ; "GRACE-FO SuperSTAR Accelerometer"@en , "GRACE-FO Star Camera Assembly"@en , "GRACE Follow-On"@en , "GRACE-FO K-Band Ranging System"@en , "GRACE-FO Laser Ranging Interferometer"@en , "Gravity Recovery and Climate Experiment Follow-On"@en , ""@en ; "CEOS IDN DIF"@en ; "9.8"^^xsd:float ; "89.0"^^xsd:float ; "https://podaac-tools.jpl.nasa.gov/drive/files/allData/gracefo/docs/" ; "JPL"@en ; "Data Center Contact"@en ; "GRACE-FO"@en , "GRACE-FO SCA"@en , "USA/NASA"@en , "GRACE-FO KBR"@en , ""@en , "GRACE-FO ACC"@en , "GRACE-FO LRI"@en ; "-89.0"^^xsd:float ; "2018-05-22"^^xsd:date ; "Month"@en ; "GRAVITY/GRAVITATIONAL FIELD"@en ; "SOLID EARTH"@en ; "none"@en ; "GRAVITY"@en ; "6.0"^^xsd:float ; "-180.0"^^xsd:float . a base: ; owl:versionInfo "2020-09-16T19:36:14.450Z" ; "Aquarius Level 3 sea surface density standard mapped image data contains gridded 1 degree spatial resolution derived density averaged over daily, 7 day, monthly, and seasonal time scales.

The Level 2B wind vectors are binned on a 12.5 km Wind Vector Cell (WVC) grid and processed using the Level 2A Sigma-0 dataset. RapidScat is a Ku-band dual beam circular rotating scatterometer retaining much of the same hardware and functionality of QuikSCAT, with exception of the antenna sub-system and digital interface to the International Space Station (ISS) Columbus module, which is where RapidScat is mounted. The NASA mission is officially referred to as ISS-RapidScat. Unlike QuikSCAT, ISS-RapidScat is not in sun-synchronous orbit, and flies at roughly half the altitude with a low inclination angle that restricts data coverage to the tropics and mid-latitude regions; the extent of latitudinal coverage stretches from approximately 61 degrees North to 61 degrees South. Furthermore, there is no consistent local time of day retrieval. This dataset is provided in a netCDF-3 file format that follows the netCDF-4 classic model (i.e., generated by the netCDF-4 API) and made available via FTP and OPeNDAP. For data access, please click on the \"Data Access\" tab above. This Version 1.2 dataset differs from the previous Version 1.1 dataset as follows: 1) L1B sigma-0 has been re-calibrated during the periods of low signal-to-noise ratio (SNR) and 2) during low SNR periods the L1B sigma-0 calibration is determined using re-pointed L1B QuikSCAT data. It is advised for users to avoid using the \"wind_obj\" variable in this dataset since it is minimally applicable and meant primarily for quality assurance; for users who wish to access the objective function values for each ambiguity, it is suggested to use only the \"ambiguity_obj\" variable. The \"wind_obj\" variable contains DIRTH probabilities (which are derived form the \"ambiguity_obj\" objective function values) in the range of 0 to 1 indicating the conditional probability that the true direction is within + or - 2.5 degrees of the retrieved wind direction given the observed backscatter measurements in the cell.

The AVHRR is a space-borne scanning sensor on the National Oceanic and Atmospheric Administration (NOAA) family of Polar Orbiting Environmental Satellites (POES) having a operational legacy that traces back to the Television Infrared Observation Satellite-N (TIROS-N) launched in 1978. AVHRR instruments measure the radiance of the Earth in 5 (or 6) relatively wide spectral bands. The first two are centered around the red (0.6 micrometer) and near-infrared (0.9 micrometer) regions, the third one is located around 3.5 micrometer, and the last two sample the emitted thermal radiation, around 11 and 12 micrometers, respectively. The legacy 5 band instrument is known as AVHRR/2 while the more recent version, the AVHRR/3 (first carried on the NOAA-15 platform), acquires data in a 6th channel located at 1.6 micrometer. Typically the 11 and 12 micron channels are used to derive SST sometimes in combination with the 3.5 micron channel. The NOAA platforms are sun synchronous generally viewing the same earth location twice a day (latitude dependent) due to the relatively large AVHRR swath of approximately 2400 km. The highest ground resolution that can be obtained from the current AVHRR instruments is 1.1 km at nadir. AVHRR data are acquired in three formats: High Resolution Picture Transmission (HRPT), Local Area Coverage (LAC), and Global Area Coverage (GAC). HRPT data are full resolution image data transmitted to a ground stations as they are collected. LAC are also full resolution data, but the acquisition is prescheduled and recorded with an on-board tape recorder for subsequent transmission during a station overpass. GAC data provide daily subsampled global coverage recorded on tape recorders and then transmitted to a ground station. This particular dataset is derived from LAC data. Further binning and averaging of the 1.1 km LAC pixels results in a final dataset resolution of 2.2 km. The coverage of the LAC data can vary but generally contains scenes over the oceans adjacent to Australia and the North Indian Ocean."@en ; "None"@en ; "EARTH SCIENCE"@en ; "2020-09-16"^^xsd:date ; "2005-12-06.

The project involves two field campaigns and a series of cruises in regions of the Atlantic and Pacific Oceans exhibiting salinity extremes. SPURS employs a suite of state-of-the-art in-situ sampling technologies that, combined with remotely sensed salinity fields from the Aquarius/SAC-D, SMAP and SMOS satellites, provide a detailed characterization of salinity structure over a continuum of spatio-temporal scales. The SPURS-2 campaign involved two month-long cruises by the R/V Revelle in August 2016 and October 2017 combined with complementary sampling on a more continuous basis over this period by the schooner Lady Amber. Focused around a central mooring located near 10N,125W, the objective of SPURS-2 was to study the dynamics of the rainfall-dominated surface ocean at the western edge of the eastern Pacific fresh pool subject to high seasonal variability and strong zonal flows associated with the North Equatorial Current and Countercurrent. The Controlled Flux Technique (CFT) is a system for measuring the net heat transfer velocity and turbulent kinetic energy (TKE) dissipation at the ocean surface, and is a useful tool for studying the turbulence generated at the ocean surface by the impact of raindrops. CFT was employed during both SPURS-2 Revelle cruises. It involves a laser heating a small patch of water on the ocean surface, and an infrared imaging camera then tracking the resulting thermal decay. This decay is known to be proportional to the dissipation of TKE at the water surface, which in turn can be used to scale the transfer velocity for the net heat flux. SPURS2 CFT data take the form of a series of .raw video files each with corresponding .met text header files containing the associated file metadata. The CFT data was recorded at 15 frames per second (fps) during the first Revelle cruise in 2016, and at 25 fps during the second in 2017.

Average daily, weekly (8 day), monthly and annual skin SST products at are available at both 4.63 and 9.26 km spatial resolution. Aqua was launched by NASA on May 4, 2002, into a sun synchronous, polar orbit with a daylight ascending node at 13:30, formation flying in the A-train with other Earth Observation Satellites (EOS), to study the global dynamics of the Earth atmosphere, land and oceans. MODIS captures data in 36 spectral bands at a variety of spatial resolutions. Two SST products can be present in these files. The first is a skin SST produced for both day and night (NSST) observations, derived from the long wave IR 11 and 12 micron wavelength channels, using a modified nonlinear SST algorithm intended to provide continuity of SST derived from heritage and current NASA sensors. At night, a second SST product is generated using the mid-infrared 3.95 and 4.05 micron wavelength channels which are unique to MODIS; the SST derived from these measurements is identified as SST4. The SST4 product has lower uncertainty, but due to sun glint can only be used at night. To generate the L3 products the L2 pixels are binned into an integerized sinusoidal area grid (ISEAG) and mapped into an equidistant cylindrical (also known as Platte Carre projection. Additional projection detailed can be found at https://oceancolor.gsfc.nasa.gov/docs/format/The NASA MODIS L3 SST data products are generated by the NASA Ocean Biology Processing Group (OBPG) and Peter Minnett and his team at the Rosenstiel School of Marine and Atmospheric Science (RSMAS) are responsible for sea surface temperature algorithm development, error statistics and quality flagging.

SPURS employs a suite of state-of-the-art in-situ sampling technologies that, combined with remotely sensed salinity fields from the Aquarius/SAC-D and SMOS satellites, provide a detailed characterization of salinity structure over a continuum of spatio-temporal scales. The SPURS-1 campaign involved a series of 5 cruises during 2012 - 2013 seeking to characterize the salinity structure and balance in a high salinity, high evaporation, and low rainfall region of the subtropical North Atlantic. It aims to resolve processes responsible for maintaining the subtropical surface salinity maximum in this region and within a 900 x 800-mile square study area centered at 25N, 38W. Approximately 83 drifters were deployed during the SPURS-1 campaign. A drifter is a passive Lagrangian sensor platform consisting of a surface buoy and tethered subsurface drogue. Drifter buoys contain GPS/ARGOS and satellite data transmitters, with sensors measuring temperature and other properties. For SPURS-1, these were standard Surface Velocity Program (SVP) drifters with salinity sensors added (SVP/S). Data for both US and European drifter deployments during SPURS-1 are available here.

This dataset contains estimates of geopotential field derived from the Gravity Recovery and Climate Experiment (GRACE) mission measurements and a non-tidal oceanic and atmospheric model produced by the Center for Space Research (CSR) at University of Texas at Austin. The data are in spherical harmonics averaged over approximately a month. The primary objective of the GRACE mission is to obtain accurate estimates of the mean and time-variable components of the gravity field variations. This objective is achieved by making continuous measurements of the change in distance between twin spacecraft, co-orbiting in about 500 km altitude, near circular, polar orbit, spaced approximately 200 km apart, using a microwave ranging system. In addition to these range change, the non-gravitional forces are measured on each satellite using a high accuracy electrostatic, room-temperature accelerometer. The satellite orientation and position (and timing) are precisely measured using twin star cameras and a GPS receiver, respectively. Spatial and temporal variations in the gravity field affect the orbits (or trajectories) of the twin spacecraft differently. These differences are manifested as changes in the distance between the spacecraft, as they orbit the Earth. This change in distance is reflected in the time-of-flight of microwave signals transmitted and received nearly simultaneously between the two spacecraft. The change in this time of fight is continuously measured by tracking the phase of the microwave carrier signals. The so called dual-one-way range change measurements can be reconstructed from these phase measurements. This range change (or its numerically derived derivatives), along with other mission and ancillary data, is subsequently analyzed to extract the parameters of an Earth gravity field model."@en ; "none"@en ; "EARTH SCIENCE"@en ; "2020-09-16"^^xsd:date ; "Dataset Creation via Metadata Tool"@en ; "https://podaac.jpl.nasa.gov/" ; "English"@en ; "GRACE"@en ; "CSR"@en ; "2018-05-10"^^xsd:date ; "JPL"@en ; "GRACE NON-TIDAL ATMOSPHERE AND OCEAN GEOPOTENTIAL COEFFICIENTS CSR (GAC)"@en ; "GRACE_GAC_L2_GRAV_CSR_RL06"@en ; "180.0"^^xsd:float ; "podaac@podaac.jpl.nasa.gov"@en ; "PODAAC-GRGAC-20C06" ; "GRACE NON-TIDAL ATMOSPHERE AND OCEAN GEOPOTENTIAL COEFFICIENTS CSR RELEASE 6.0 GAC"@en ; ""@en ; "Geoscientific Information"@en , "Oceans"@en ; "2018-04-26"^^xsd:date ; ""@en ; "Geographic Region"@en ; "Global"@en ; "Star Camera Assembly"@en , "GRACE SuperSTAR Accelerometer"@en , "Gravity Recovery and Climate Experiment"@en , "GRACE K-Band Ranging System"@en , ""@en ; "CEOS IDN DIF"@en ; "9.8"^^xsd:float ; "88.0"^^xsd:float ; "https://podaac-tools.jpl.nasa.gov/drive/files/allData/grace/L2/CSR/RL05/docs/" ; "GRACE/CSR"@en ; "Data Center Contact"@en ; "GRACE SCA"@en , "GRACE ACC"@en , "USA/NASA"@en , "GRACE"@en , "GRACE KBR"@en , ""@en ; "-88.0"^^xsd:float ; "2002-04-05"^^xsd:date ; "2017-06-30"^^xsd:date ; "GRAVITY/GRAVITATIONAL FIELD"@en ; "SOLID EARTH"@en ; "none"@en ; "GRAVITY"@en ; "6.0"^^xsd:float ; "-180.0"^^xsd:float . a base: ; owl:versionInfo "2020-09-16T19:36:14.396Z" ; "These data are near-real-time (NRT) (within 7-9 hours of measurement) sea surface height anomalies (SSHA) from the AltiKa altimeter onboard the Satellite with ARgos and ALtiKa (SARAL).

At night, a second SST product is generated using the mid-infrared 3.95 and 4.05 micron wavelength channels which are unique to MODIS; the SST derived from these measurements is identified as SST4. The SST4 product has lower uncertainty, but due to sun glint can only be used at night.

The CCMP datasets combine cross-calibrated satellite winds obtained from Remote Sensing Systems (REMSS) using a Variational Analysis Method (VAM) to produce a high-resolution (0.25 degree) gridded analysis. The CCMP data set includes cross-calibrated satellite winds derived from SSM/I, SSMIS, AMSR-E, TRMM TMI, QuikSCAT, SeaWinds, WindSat and other satellite instruments as they become available from REMSS. REMSS uses a cross-calibrated sea-surface emissivity model function which improves the consistency between wind speed retrievals from microwave radiometers (i.e., SSM/I, SSMIS, AMSR, TMI, WindSat) and those from scatterometers (i.e., QuikSCAT and SeaWinds). The VAM combines these data with in situ measurements and a starting estimate (first guess) of the wind field. The European Center for Medium-Range Weather Forecasts (ECMWF) ERA-40 Reanalysis is used as the first-guess from 1987 to 1998. The ECMWF Operational analysis is used from January 1999 onward. All wind observations and analysis fields are referenced to a height of 10 meters. The ERA-40 can be obtained from the Computation and Information Systems Laboratory (CISL) at the National Center for Atmospheric Research (NCAR): http://rda.ucar.edu/datasets/ds117.0/. The ECMWF Operational analysis can also be obtained from CISL at NCAR: http://rda.ucar.edu/datasets/ds111.1/. Three products are distributed to complete the CCMP dataset series. L3.0 product contains high-resolution analyses every 6-hours. These data are then time averaged over monthly and 5-day periods to derive the L3.5 product. Directions from the L3.0 product are then assigned to the time and location of the passive microwave satellite wind speed observations to derive the L2.5 product. All datasets are distributed on a 0.25 degree cylindrical coordinate grid. This dataset is one in a series of First-Look (FLK) CCMP datasets and is a continuation and expansion of the SSM/I surface wind velocity project that began under the NASA Pathfinder Program. Refinements and upgrades to the FLK version will be incorporated under a new release (date to be determined) known as Late-look (LLK) and may include additional satellite datasets. All satellite surface wind data are obtained from REMSS under the DISCOVER project: Distributed Information Services: Climate/Ocean Products and Visualizations for Earth Research (http://www.discover-earth.org/index.html). The CCMP project is the result of an investigation funded by the NASA Making Earth Science data records for Use in Research Environments (MEaSUREs) program (http://community.eosdis.nasa.gov/measures/). In accordance with the MEaSUREs program, the CCMP datasets are also known as Earth System Data Records (ESDRs). In collaboration with private and government institutions, a team led by Dr. Robert Atlas (PI; proposal originally solicited by REASoN, and currently funded by MEaSURES) has created the CCMP project to provide multi-instrument ocean surface wind velocity ESDRs, with wide ranging research applications in meteorology and oceanography."@en ; "NONE"@en ; "EARTH SCIENCE"@en ; "2020-09-16"^^xsd:date ; "Dataset Policy created for CCMP_MEASURES_ATLAS_L4_OW_L3_5A_MONTHLY_WIND_VECTORS_FLK"@en ; "https://podaac.jpl.nasa.gov/" ; "English"@en ; "NASA/GSFC/NOAA"@en ; "PO.DAAC"@en ; "2009-05-08"^^xsd:date ; "PO.DAAC"@en ; "Cross-Calibrated Multi-Platform Ocean Surface Wind Vector L3.5A Monthly First-Look Analyses"@en ; "Cross-Calibrated Multi-Platform Ocean Surface Wind Vector L3.5A Monthly First-Look Analyses"@en ; "360.0"^^xsd:float ; "podaac@podaac.jpl.nasa.gov"@en ; "PODAAC-CCF35-01AM1" ; "Cross-Calibrated Multi-Platform Ocean Surface Wind Vector L3.5A Monthly First-Look Analyses"@en ; ""@en ; "Geoscientific Information"@en , "Oceans"@en ; "2017-04-28"^^xsd:date ; ""@en ; "0.25"^^xsd:float ; "Geographic Region"@en ; "Global"@en ; "Making Earth Science Data Records for Use in Research Environments"@en , "Advanced Earth Observing Satellite-II"@en , ""@en , "Special Sensor Microwave Imager/Sounder"@en , "Defense Meteorological Satellite Program-F14"@en , "Defense Meteorological Satellite Program-F17"@en , "Defense Meteorological Satellite Program-F08"@en , "TRMM Microwave Imager"@en , "Defense Meteorological Satellite Program-F10"@en , "Defense Meteorological Satellite Program-F13"@en , "Advanced Microwave Scanning Radiometer-EOS"@en , "QUIKSCAT"@en , "Defense Meteorological Satellite Program-F15"@en , "Tropical Rainfall Measuring Mission"@en , "Special Sensor Microwave Imager"@en , "SeaWinds Scatterometer"@en , "Defense Meteorological Satellite Program-F11"@en , "Coriolis"@en , "Earth Observing System, AQUA"@en , "WindSat"@en ; "0.25"^^xsd:float ; "CEOS IDN DIF"@en ; "9.8"^^xsd:float ; "78.0"^^xsd:float ; "https://podaac-tools.jpl.nasa.gov/drive/files/allData/ccmp/L3.5a/docs/ccmp_users_guide.pdf" ; "NASA/GSFC/NOAA"@en ; "Data Center Contact"@en ; "DMSP 5D-2/F10"@en , "SSM/I"@en , ""@en , "TMI"@en , "TRMM"@en , "MEaSUREs"@en , "DMSP 5D-2/F14"@en , "WINDSAT"@en , "Aqua"@en , "ADEOS-II"@en , "AMSR-E"@en , "DMSP 5D-2/F13"@en , "SEAWINDS"@en , "DMSP 5D-3/F17"@en , "QUIKSCAT"@en , "CORIOLIS"@en , "USA/NASA"@en , "SSMIS"@en , "DMSP 5D-2/F8"@en , "DMSP 5D-3/F15"@en , "DMSP 5D-2/F11"@en ; "-78.0"^^xsd:float ; "1987-07-02"^^xsd:date ; "2011-12-31"^^xsd:date ; "1 Month"@en ; "OCEAN WINDS"@en ; "OCEANS"@en ; "NONE"@en ; "SURFACE WINDS"@en ; "1.0"^^xsd:float ; "0.0"^^xsd:float . a base: ; owl:versionInfo "2020-09-16T19:36:14.530Z" , "2020-09-16T19:36:14.585Z" ; "The SPURS (Salinity Processes in the Upper Ocean Regional Study) project is a NASA-funded oceanographic process study and associated field program that aim to elucidate key mechanisms responsible for near-surface salinity variations in the oceans.

The AVHRR is a space-borne scanning sensor on the National Oceanic and Atmospheric Administration (NOAA) family of Polar Orbiting Environmental Satellites (POES) having a operational legacy that traces back to the Television Infrared Observation Satellite-N (TIROS-N) launched in 1978. AVHRR instruments measure the radiance of the Earth in 5 (or 6) relatively wide spectral bands. The first two are centered around the red (0.6 micrometer) and near-infrared (0.9 micrometer) regions, the third one is located around 3.5 micrometer, and the last two sample the emitted thermal radiation, around 11 and 12 micrometers, respectively. The legacy 5 band instrument is known as AVHRR/2 while the more recent version, the AVHRR/3 (first carried on the NOAA-15 platform), acquires data in a 6th channel located at 1.6 micrometer. Typically the 11 and 12 micron channels are used to derive SST sometimes in combination with the 3.5 micron channel. The NOAA platforms are sun synchronous generally viewing the same earth location twice a day (latitude dependent) due to the relatively large AVHRR swath of approximately 2400 km. The highest ground resolution that can be obtained from the current AVHRR instruments is 1.1 km at nadir. AVHRR data are acquired in three formats: High Resolution Picture Transmission (HRPT), Local Area Coverage (LAC), and Global Area Coverage (GAC). HRPT data are full resolution image data transmitted to a ground stations as they are collected. LAC are also full resolution data, but the acquisition is prescheduled and recorded with an on-board tape recorder for subsequent transmission during a station overpass.

Average daily, weekly (8 day), monthly and annual skin SST products at are available at both 4.63 and 9.26 km spatial resolution. Aqua was launched by NASA on May 4, 2002, into a sun synchronous, polar orbit with a daylight ascending node at 13:30, formation flying in the A-train with other Earth Observation Satellites (EOS), to study the global dynamics of the Earth atmosphere, land and oceans. MODIS captures data in 36 spectral bands at a variety of spatial resolutions. Two SST products can be present in these files. The first is a skin SST produced for both day and night (NSST) observations, derived from the long wave IR 11 and 12 micron wavelength channels, using a modified nonlinear SST algorithm intended to provide continuity of SST derived from heritage and current NASA sensors. At night, a second SST product is generated using the mid-infrared 3.95 and 4.05 micron wavelength channels which are unique to MODIS; the SST derived from these measurements is identified as SST4. The SST4 product has lower uncertainty, but due to sun glint can only be used at night. To generate the L3 products the L2 pixels are binned into an integerized sinusoidal area grid (ISEAG) and mapped into an equidistant cylindrical (also known as Platte Carre projection. Additional projection detailed can be found at https://oceancolor.gsfc.nasa.gov/docs/format/The NASA MODIS L3 SST data products are generated by the NASA Ocean Biology Processing Group (OBPG) and Peter Minnett and his team at the Rosenstiel School of Marine and Atmospheric Science (RSMAS) are responsible for sea surface temperature algorithm development, error statistics and quality flagging.

The retrievals are provided on a non-uniform grid within the swath at 25 km pixel resolution. Each L2B file corresponds to a specific orbital revolution (rev) number, which begins at the southernmost point of the ascending orbit. An ASCII inline quality report (Q2B) has been generated for each L2B file; each Q2B file provides statistics of various quality elements pertaining to the processing of a specific L2B file.

For example, one SIR file for a particular day will contain the globally gridded average Sigma-0 values for the horizontally polarized L1B retrievals, while the other will contain those from the vertically polarized L1B retrievals. These SIR files were also used to generate a complimentary dataset of GIF images representing the daily averaged Sigma-0, which is meant for browse purposes only and available here: http://podaac.jpl.nasa.gov/dataset/SEAWINDS_BYU_L3_OW_SIGMA0_GLOBAL_RECTANGULAR_BROWSE_IMAGES.

Average daily, weekly (8 day), monthly and annual skin SST products are available at both 4.63 and 9.26 km spatial resolution. Terra was launched by NASA on December 18, 1999, into a sun synchronous, polar orbit with a daylight descending node at 10:30 am, to study the global dynamics of the Earth atmosphere, land and oceans. The MODIS captures data in 36 spectral bands at a variety of spatial resolutions. Two SST products can be present in these files. The first is a skin SST produced for both day and night observations, derived from the long wave IR 11 and 12 micron wavelength channels, using a modified nonlinear SST algorithm intended to provide continuity with SST derived from heritage and current NASA sensors. At night, a second SST product is produced using the mid-infrared 3.95 and 4.05 micron channels which are unique to MODIS; the SST derived from these measurements is identified as SST4. The SST4 product has lower uncertainty, but due to sun glint can only be produced at night. To generate the L3 products the L2 pixels are binned into an integerized sinusoidal area grid (ISEAG) and mapped into an equidistant cylindrical (also known as Platte Carre) projection. Additional projection detailed can be found at https://oceancolor.gsfc.nasa.gov/docs/format/The NASA MODIS L3 SST data products are generated by the NASA Ocean Biology Processing Group (OBPG) Peter Minnett and his team at the Rosenstiel School of Marine and Atmospheric Science (RSMAS) are responsible for sea surface temperature algorithm development, error statistics and quality flagging.

All of the collocated radiometer data is produced by RSS. The co-located radiometer sources include: 1) DMSP SSM/I (F15) and SSMIS (F16/F17), 2) Coriolis WindSat, 3) GCOM-W1 AMSR2 and 4) GPM Core GMI; more details on these radiometer sources and sensors can be extracted by scrolling down to the \"Platform/Sensor\" section below this description.

The project is comprised of two field campaigns and a series of cruises in regions of the Atlantic and Pacific Oceans exhibiting salinity extremes. SPURS employs a suite of state-of-the-art in-situ sampling technologies that, combined with remotely sensed salinity fields from the Aquarius/SAC-D, SMAP and SMOS satellites, provide a detailed characterization of salinity structure over a continuum of spatio-temporal scales. The SPURS-2 campaign involved two month-long cruises by the R/V Revelle in August 2016 and October 2017 combined with complementary sampling on a more continuous basis over this period by the schooner Lady Amber. Focused around a central mooring located near 10N,125W, the objective of SPURS-2 was to study the dynamics of the rainfall-dominated surface ocean at the western edge of the eastern Pacific fresh pool subject to high seasonal variability and strong zonal flows associated with the North Equatorial Current and Countercurrent. The towed Surface Salinity Profiler (SSP) platform is a converted paddleboard with a keel and surfboard outrigger that is tethered to the ship and skims the sea surface beyond the ships wake. Below the paddleboard are salinity and temperature sensors at depths of 10, 30, 50 and 100cm, and microstructure sensors that measure turbulence. The SSP was deployed 19 times throughout the first SPURS-2 cruise, totaling over 200 hours of measurements, and a further 15 times during the 2017 cruise. SSP deployment is most informative when there is a rain event leading to near-surface ocean stratification. The SSP then measures how the ocean changes over the periods before, during, and after rain, and how rainwater mixes into the ocean during recovery.

Enhancements with this release include: use of an improved 0.125 degree land correction table with land emission based on SMAP TB; replacement of the previous NCEP sea-ice mask with one based on RSS AMSR-2 and implementing a sea-ice threshold of 0.3% (gain weighted sea-ice fraction); revised solar flagging that depends on glint angle and wind speed; inclusion of estimated SSS-uncertainty; consolidation of both 40KM and 70KM SMAP-SSS datasets as variable fields in a single data product.

Aqua was launched by NASA on May 4, 2002, into a sun synchronous, polar orbit with a daylight ascending node at 13:30, formation flying in the A-train with other Earth Observation Satellites (EOS), to study the global dynamics of the Earth atmosphere, land and oceans. MODIS captures data in 36 spectral bands at a variety of spatial resolutions. Two SST products can be present in these files. The first is a skin SST produced for both day and night (NSST) observations, derived from the long wave IR 11 and 12 micron wavelength channels, using a modified nonlinear SST algorithm intended to provide continuity of SST derived from heritage and current NASA sensors. At night, a second SST product is generated using the mid-infrared 3.95 and 4.05 micron wavelength channels which are unique to MODIS; the SST derived from these measurements is identified as SST4. The SST4 product has lower uncertainty, but due to sun glint can only be used at night. To generate the L3 products the L2 pixels are binned into an integerized sinusoidal area grid (ISEAG) and mapped into an equidistant cylindrical (also known as Platte Carre projection.

The Level 2 Delay Doppler Map (DDM) data are used in the direct processing of the average wind speed and MSS data that are binned on the Level 3 grid. A subset of DDM data used in the direct processing of the average wind speed and MSS is co-located inside of the Level 2 data files. A single netCDF-4 data file is produced for each day of operation with an approximate 6 day latency. The reported sample locations are determined by the specular points corresponding to the Delay Doppler Maps (DDMs). The Version 1.0 CDR represents the first climate-quality release and is a collection of reanalysis products derived from the SDR v2.1 Level 1 data. Calibration accuracy and long term stability are improved relative to the SDR v2.1 using a new trackwise correction algorithm which constrains the average value of the L1 data using MERRA-2 reanalysis wind speeds. Details of the algorithm are provided in the Trackwise Corrected CDR Algorithm Theoretical Basis Document. CDR Level 2 and 3 products (ocean surface wind speed, mean square slope, and latent and sensible heat flux) are generated from the CDR L1 data using the v2.1 SDR data processing algorithms. These products also exhibit improved calibration accuracy and stability over SDR v2.1. Trackwise correction is applied to the two primary CYGNSS L1 science data products the normalized bistatic radar cross section (NBRCS) and the leading edge slope of the Doppler-integrated delay waveform (LES). The correction compensates for variations in the transmit power level of the GPS signals measured by the CYGNSS bistatic radar receivers. The SDR v2.1 L1 algorithm assumes a constant GPS transmit power and variations in it can be misinterpreted as variations in the L1 data and in subsequent L2 science data products derived from them. The GPS constellation consists of several different satellite models (a.k.a. block types) and the level of transmit power variation differs between them. The more recent Block IIF models (which account for ~37% of the GPS constellation) have significantly larger variations than the older models and, for this reason, they have been screened out and not used to produce SDR v2.1 L2 or L3 science data products. Trackwise correction eliminates the need for this screening so CDR L2 and L3 data products now include Block IIF samples. It should be noted that the trackwise correction algorithm cannot be successfully applied to all SDR v2.1 L1 data so there is also some loss of samples that were present in SDR v2.1. Overall, there is a significant increase in sampling and improvement in spatial coverage with the CDR products."@en ; "NONE"@en ; "EARTH SCIENCE"@en ; "2020-09-16"^^xsd:date ; "Dataset Creation via Metadata Tool"@en ; "https://podaac.jpl.nasa.gov/" ; "English"@en ; "CYGNSS"@en ; "PO.DAAC"@en ; "2020-05-22"^^xsd:date ; "PO.DAAC"@en ; "CYGNSS Level 3 Climate Data Record"@en ; "CYGNSS Level 2 Climate Data Record Version 1.0"@en ; "360.0"^^xsd:float ; "podaac@podaac.jpl.nasa.gov"@en ; "PODAAC-CYGNS-L3C10" ; "CYGNSS Level 3 Climate Data Record Version 1.0"@en ; ""@en ; "Oceans"@en , "Geoscientific Information"@en ; "2019-12-09"^^xsd:date ; ""@en ; "0.2"^^xsd:float ; "Geographic Region"@en ; "Global"@en ; "Cyclone Global Navigation Satellite System"@en , "Delay Doppler Mapping Instrument"@en , ""@en ; "0.2"^^xsd:float ; "CEOS IDN DIF"@en ; "9.8"^^xsd:float ; "40.0"^^xsd:float ; "http://clasp-research.engin.umich.edu/missions/cygnss/" ; "UMICH/ENG/CSSE"@en ; "Data Center Contact"@en ; ""@en , "DDMI"@en , "CYGNSS"@en , "USA/NASA"@en ; "40.0"^^xsd:float ; "2017-03-18"^^xsd:date ; "Daily"@en ; "OCEAN WINDS"@en ; "OCEANS"@en ; "NONE"@en ; "SURFACE WINDS"@en ; "1.0"^^xsd:float ; "0.0"^^xsd:float . a base: ; owl:versionInfo "2020-09-16T19:36:14.524Z" , "2020-09-16T19:36:14.579Z" ; "The ACSPO H08/AHI L3C (Level 3 Collated) product is a gridded version of the ACSPO H08/AHI L2P product available at https://podaac.jpl.nasa.gov/dataset/AHI_H08-STAR-L2P-v2.70.

The project is comprised of two field campaigns and a series of cruises in regions of the Atlantic and Pacific Oceans exhibiting salinity extremes. SPURS employs a suite of state-of-the-art in-situ sampling technologies that, combined with remotely sensed salinity fields from the Aquarius/SAC-D, SMAP and SMOS satellites, provide a detailed characterization of salinity structure over a continuum of spatio-temporal scales. The SPURS-2 campaign involved two month-long cruises by the R/V Revelle in August 2016 and October 2017 combined with complementary sampling on a more continuous basis over this period by the schooner Lady Amber. Focused around a central mooring located near 10N,125W, the objective of SPURS-2 was to study the dynamics of the rainfall-dominated surface ocean at the western edge of the eastern Pacific fresh pool subject to high seasonal variability and strong zonal flows associated with the North Equatorial Current and Countercurrent. Two PICO moorings (PMEL 9N and 11N) were deployed on the Revelle cruise in September 2016 in northern and southern domain quadrants at 9deg2.830N, 124deg59.833W and N10:59.0498, W124:57.531 respectively. These moorings contained a surface meteorological package and a \"prawler\", a CTD that crawls up and down the mooring line from 4-450m, yielding time series of salinity and temperature profile data at fixed locations (nominally 8 profiles per day). The moorings were recovered on the second Revelle cruise (Oct. 22 & Nov. 2, 2017).

This dataset contains estimates of ocean bottom pressure derived from the Gravity Recovery and Climate Experiment (GRACE) mission measurements, produced by the German Research Centre for Geosciences (GFZ). The data are in spherical harmonics averaged over approximately a month. The primary objective of the GRACE mission is to obtain accurate estimates of the mean and time-variable components of the gravity field variations. This objective is achieved by making continuous measurements of the change in distance between twin spacecraft, co-orbiting in about 500 km altitude, near circular, polar orbit, spaced approximately 200 km apart, using a microwave ranging system. In addition to these range change, the non-gravitional forces are measured on each satellite using a high accuracy electrostatic, room-temperature accelerometer. The satellite orientation and position (and timing) are precisely measured using twin star cameras and a GPS receiver, respectively. Spatial and temporal variations in the gravity field affect the orbits (or trajectories) of the twin spacecraft differently. These differences are manifested as changes in the distance between the spacecraft, as they orbit the Earth. This change in distance is reflected in the time-of-flight of microwave signals transmitted and received nearly simultaneously between the two spacecraft. The change in this time of fight is continuously measured by tracking the phase of the microwave carrier signals. The so called dual-one-way range change measurements can be reconstructed from these phase measurements. This range change (or its numerically derived derivatives), along with other mission and ancillary data, is subsequently analyzed to extract the parameters of an Earth gravity field model."@en ; "none"@en ; "EARTH SCIENCE"@en ; "2020-09-16"^^xsd:date ; "Dataset Creation via Metadata Tool"@en ; "https://podaac.jpl.nasa.gov/" ; "English"@en ; "GRACE"@en ; "GFZ"@en ; "2018-08-31"^^xsd:date ; "JPL PO.DAAC"@en ; "GRACE OCEAN BOTTOM GEOPOTENTIAL COEFFICIENTS GFZ (GAD)"@en ; "GRACE_GAD_L2_GRAV_GFZ_RL06"@en ; "180.0"^^xsd:float ; "podaac@podaac.jpl.nasa.gov"@en ; "PODAAC-GRGAD-20G06" ; "GRACE OCEAN BOTTOM GEOPOTENTIAL COEFFICIENTS GFZ RELEASE 6.0 GAD"@en ; ""@en ; "Oceans"@en , "Geoscientific Information"@en ; "2018-08-06"^^xsd:date ; ""@en ; "Geographic Region"@en ; "Global"@en ; "GRACE SuperSTAR Accelerometer"@en , "GRACE K-Band Ranging System"@en , ""@en , "Gravity Recovery and Climate Experiment"@en , "Star Camera Assembly"@en ; "CEOS IDN DIF"@en ; "9.8"^^xsd:float ; "88.0"^^xsd:float ; "https://podaac-tools.jpl.nasa.gov/drive/files/allData/grace/docs/" ; "GRACE/GFZ"@en ; "Data Center Contact"@en ; "GRACE ACC"@en , "GRACE SCA"@en , "GRACE KBR"@en , "GRACE"@en , ""@en , "USA/NASA"@en ; "-88.0"^^xsd:float ; "2002-04-05"^^xsd:date ; "2017-07-01"^^xsd:date ; "GRAVITY/GRAVITATIONAL FIELD"@en ; "SOLID EARTH"@en ; "none"@en ; "GRAVITY"@en ; "6.0"^^xsd:float ; "-180.0"^^xsd:float . a base: ; owl:versionInfo "2020-09-16T19:36:14.277Z" ; "This dataset is derived under the Cross-Calibrated Multi-Platform (CCMP) project and contains value-added Special Sensor Microwave Imager (SSM/I) ocean surface winds from the Defense Meteorological Satellite Program (DMSP) F13 platform. The CCMP datasets combine cross-calibrated satellite winds obtained from Remote Sensing Systems (REMSS) using a Variational Analysis Method (VAM) to produce a high-resolution (0.25 degree) gridded analysis. Wind directions from the resulting analysis are assigned to the location and time of the satellite-derived wind speed observations to create this value added dataset. The CCMP data set includes cross-calibrated satellite winds derived from SSM/I, SSMIS, AMSR-E, TRMM TMI, QuikSCAT, SeaWinds, WindSat and other satellite instruments as they become available from REMSS. REMSS uses a cross-calibrated sea-surface emissivity model function which improves the consistency between wind speed retrievals from microwave radiometers (i.e., SSM/I, SSMIS, AMSR, TMI, and WindSat) and those from scatterometers (i.e., QuikSCAT and SeaWinds). The VAM combines these data with in situ measurements and a starting estimate (first guess) of the wind field. The European Center for Medium-Range Weather Forecasts (ECMWF) ERA-40 Reanalysis is used as the first-guess from 1987 to 1998. The ECMWF Operational analysis is used from January 1999 onward. All wind observations and analysis fields are referenced to a height of 10 meters. The ERA-40 can be obtained from the Computation and Information Systems Laboratory (CISL) at the National Center for Atmospheric Research (NCAR): http://rda.ucar.edu/datasets/ds117.0/. The ECMWF Operational analysis can also be obtained from CISL at NCAR: http://rda.ucar.edu/datasets/ds111.1/. Three products are distributed to complete the CCMP dataset series. L3.0 product contains high-resolution analyses every 6-hours. These data are then time averaged over monthly and 5-day periods to derive the L3.5 product. Directions from the L3.0 product are then assigned to the time and location of the passive microwave satellite wind speed observations to derive the L2.5 product. All datasets are distributed on a 0.25 degree cylindrical coordinate grid. This dataset is one in a series of First-Look (FLK) CCMP datasets and is a continuation and expansion of the SSM/I surface wind velocity project that began under the NASA Pathfinder Program. Refinements and upgrades to the FLK version will be incorporated under a new release (date to be determined) known as Late-look (LLK) and may include additional satellite datasets. All satellite surface wind data are obtained from REMSS under the DISCOVER project: Distributed Information Services: Climate/Ocean Products and Visualizations for Earth Research (http://www.discover-earth.org/index.html). The CCMP project is the result of an investigation funded by the NASA Making Earth Science data records for Use in Research Environments (MEaSUREs) program (http://community.eosdis.nasa.gov/measures/). In accordance with the MEaSUREs program, the CCMP datasets are also known as Earth System Data Records (ESDRs). In collaboration with private and government institutions, a team led by Dr. Robert Atlas (PI; proposal originally solicited by REASoN, and currently funded by MEaSURES) has created the CCMP project to provide multi-instrument ocean surface wind velocity ESDRs, with wide ranging research applications in meteorology and oceanography."@en ; "NONE"@en ; "EARTH SCIENCE"@en ; "2020-09-16"^^xsd:date ; "Dataset Creation"@en ; "https://podaac.jpl.nasa.gov/" ; "English"@en ; "NASA/GSFC/NOAA"@en ; "PO.DAAC"@en ; "2009-05-08"^^xsd:date ; "PO.DAAC"@en ; "Cross-Calibrated Multi-Platform Ocean Surface Wind Vector L2.5 First-Look SSM/I-F13 Microwave Analyses"@en ; "Cross-Calibrated Multi-Platform Ocean Surface Wind Vector L2.5 First-Look SSM/I-F13 Microwave Analyses"@en ; "360.0"^^xsd:float ; "podaac@podaac.jpl.nasa.gov"@en ; "PODAAC-CCF25-01F13" ; "Cross-Calibrated Multi-Platform Ocean Surface Wind Vector L2.5 First-Look SSM/I-F13 Microwave Analyses"@en ; ""@en ; "Oceans"@en , "Geoscientific Information"@en ; "2011-01-21"^^xsd:date ; ""@en ; "0.25"^^xsd:float ; "Geographic Region"@en ; "Global"@en ; "Making Earth Science Data Records for Use in Research Environments"@en , "Special Sensor Microwave Imager"@en , ""@en , "Defense Meteorological Satellite Program-F13"@en ; "0.25"^^xsd:float ; "CEOS IDN DIF"@en ; "9.8"^^xsd:float ; "89.875"^^xsd:float ; "https://podaac-tools.jpl.nasa.gov/drive/files/allData/ccmp/L2.5/docs/ccmp_users_guide.pdf" ; "NASA/GSFC/NOAA"@en ; "Data Center Contact"@en ; "MEaSUREs"@en , ""@en , "USA/NASA"@en , "DMSP 5D-2/F13"@en , "SSM/I"@en ; "-89.875"^^xsd:float ; "1995-05-03"^^xsd:date ; "2009-11-18"^^xsd:date ; "12 Hour"@en ; "OCEAN WINDS"@en ; "OCEANS"@en ; "NONE"@en ; "SURFACE WINDS"@en ; "1.0"^^xsd:float ; "0.0"^^xsd:float . a base: ; owl:versionInfo "2020-09-16T19:36:14.569Z" , "2020-09-16T19:36:14.602Z" ; "Day and night spatially gridded (L3) global NASA skin sea surface temperature (SST) products from the Moderate-resolution Imaging Spectroradiometer (MODIS) onboard the Terra satellite. Average daily, weekly (8 day), monthly and annual skin SST products are available at both 4.63 and 9.26 km spatial resolution. Terra was launched by NASA on December 18, 1999, into a sun synchronous, polar orbit with a daylight descending node at 10:30 am, to study the global dynamics of the Earth atmosphere, land and oceans. The MODIS captures data in 36 spectral bands at a variety of spatial resolutions. Two SST products can be present in these files. The first is a skin SST produced for both day and night observations, derived from the long wave IR 11 and 12 micron wavelength channels, using a modified nonlinear SST algorithm intended to provide continuity with SST derived from heritage and current NASA sensors. At night, a second SST product is produced using the mid-infrared 3.95 and 4.05 micron channels which are unique to MODIS; the SST derived from these measurements is identified as SST4. The SST4 product has lower uncertainty, but due to sun glint can only be produced at night. To generate the L3 products the L2 pixels are binned into an integerized sinusoidal area grid (ISEAG) and mapped into an equidistant cylindrical (also known as Platte Carre) projection. Additional projection detailed can be found at https://oceancolor.gsfc.nasa.gov/docs/format/The NASA MODIS L3 SST data products are generated by the NASA Ocean Biology Processing Group (OBPG) Peter Minnett and his team at the Rosenstiel School of Marine and Atmospheric Science (RSMAS) are responsible for sea surface temperature algorithm development, error statistics and quality flagging.

Version 1.3 is intended as a replacement and continuation of the Version 1.1 and Version 1.2 data forward from orbital revolution number 7873, corresponding to 11 February 2016; on 11 Feb 2016, RapidScat entered it's 3rd low signal to noise ratio (SNR) state and the initial calibration of low SNR 3 was preliminary during the Version 1.2 release. The fundamental difference between Version 1.3 and the previous Version 1.2 datasets is that the L1B sigma-0 has been re-calibrated during the periods of low SNR states 3 and 4 using re-pointed QuikSCAT data. Due to the circular scan of the RapidScat instrument the expected number of Sigma-0 cells per WVC is not constant. To minimize the L2A data volume, the Sigma-0 cell data are stored as \"lists\" for each WVC row, with each list indexed by a \"cell_index\" array to indicate the cross-track WVC membership of the data. Each cell is then checked for land or ice and flagged accordingly. Attenuation corrections for each Sigma-0 measurement are also provided. Data are provided in single-orbit files in HDF-4 format. RapidScat is a Ku-band dual beam circular rotating scatterometer retaining much of the same hardware and functionality of QuikSCAT, with exception of the antenna sub-system and digital interface to the International Space Station (ISS) Columbus module, which is where RapidScat is mounted.

The project is comprised of two field campaigns and a series of cruises in regions of the Atlantic and Pacific Oceans exhibiting salinity extremes. SPURS employs a suite of state-of-the-art in-situ sampling technologies that, combined with remotely sensed salinity fields from the Aquarius/SAC-D, SMAP and SMOS satellites, provide a detailed characterization of salinity structure over a continuum of spatio-temporal scales. The SPURS-2 campaign involved two month-long cruises by the R/V Revelle in August 2016 and October 2017 combined with complementary sampling on a more continuous basis over this period by the schooner Lady Amber. Focused around a central mooring located near 10N,125W, the objective of SPURS-2 was to study the dynamics of the rainfall-dominated surface ocean at the western edge of the eastern Pacific fresh pool subject to high seasonal variability and strong zonal flows associated with the North Equatorial Current and Countercurrent. During both Revelle cruises, continuous measurements of the partial pressure of CO2 (pCO2), dissolved inorganic carbon (DIC), and pH at surface (0m) and 5m depths were made on water pumped continuously from the Salinity Snake and the ship's intake port. In addition to these measurements, observational data from the salinity snake and thermosalinograph also include water temperature and salinity time series at the same depths. The temporal resolution of the observations range from 3 seconds (pH) to 3 minutes (DIC). All pCO2 and associated underway data comprising this dataset are in netCDF file format with standards compliant metadata.

Other useful scientific and engineering measurement parameters include the DDM of Normalized Bistatic Radar Cross Section (NBRCS), the Delay Doppler Map Average (DDMA) of the NBRCS near the specular reflection point, and the Leading Edge Slope (LES) of the integrated delay waveform. The L1 dataset contains a number of other engineering and science measurement parameters, including sets of quality flags/indicators, error estimates, and bias estimates as well as a variety of orbital, spacecraft/sensor health, timekeeping, and geolocation parameters. At most, 8 netCDF data files (each file corresponding to a unique spacecraft in the CYGNSS constellation) are provided each day; under nominal conditions, there are typically 6-8 spacecraft retrieving data each day, but this can be maximized to 8 spacecraft under special circumstances in which higher than normal retrieval frequency is needed (i.e., during tropical storms and or hurricanes). Latency is approximately 1 month, depending on the availability of the MERRA wind speed reanalysis. The Version 1.0 CDR represents the first climate-quality release and is a collection of reanalysis products derived from the v2.1 Level 1 data. Calibration accuracy and long term stability are improved relative to the SDR v2.1 using a new trackwise correction algorithm which constrains the average value of the L1 data using MERRA-2 reanalysis wind speeds. Details of the algorithm are provide in the Trackwise Corrected CDR Algorithm Theoretical Basis Document. The CDR exhibits improved calibration accuracy and stability over v2.1. Trackwise correction is applied to the two primary CYGNSS L1 science data products the normalized bistatic radar cross section (NBRCS) and the leading edge slope of the Doppler-integrated delay waveform (LES). The correction compensates for variations in the transmit power level of the GPS signals measured by the CYGNSS bistatic radar receivers. By comparison, the v2.1 SDR L1 algorithm assumes a constant GPS transmit power, and variations in it can be misinterpreted as variations in the L1 data and in subsequent L2 science data products derived from them. The GPS constellation consists of several different satellite models (a.k.a. block types) and the level of transmit power variation differs between them. The more recent Block IIF models (which account for ~37% of the GPS constellation) have significantly larger variations than the older models and, for this reason, they have been screened out and not used to produce v2.1 L2 or L3 science data products. Trackwise correction eliminates the need for this screening so CDR L2 and L3 data products now include Block IIF samples. It should be noted that the trackwise correction algorithm cannot be successfully applied to all v2.1 SDR L1 data, so there is also some loss of samples that were present in v2.1. Overall, there is a significant increase in sampling and improvement in spatial coverage with the CDR products."@en ; "NONE"@en ; "EARTH SCIENCE"@en ; "2020-09-16"^^xsd:date ; "Dataset Creation via Metadata Tool"@en ; "https://podaac.jpl.nasa.gov/" ; "English"@en ; "CYGNSS"@en ; "PO.DAAC"@en ; "2020-05-22"^^xsd:date ; "PO.DAAC"@en ; "CYGNSS Level 1 Climate Data Record"@en ; "CYGNSS Level 1 Climate Data Record Version 1.0"@en ; "360.0"^^xsd:float ; "podaac@podaac.jpl.nasa.gov"@en ; "PODAAC-CYGNS-L1C10" ; "CYGNSS Level 1 Climate Data Record Version 1.0"@en ; ""@en ; "Geoscientific Information"@en , "Oceans"@en ; "2020-04-01"^^xsd:date ; ""@en ; "Geographic Region"@en ; "Global"@en ; ""@en , "Delay Doppler Mapping Instrument"@en , "Cyclone Global Navigation Satellite System"@en ; "CEOS IDN DIF"@en ; "9.8"^^xsd:float ; "40.0"^^xsd:float ; "http://clasp-research.engin.umich.edu/missions/cygnss/" ; "NASA/ESSP/UMICH/CYGNSS"@en ; "Data Center Contact"@en ; ""@en , "CYGNSS"@en , "USA/NASA"@en , "DDMI"@en ; "40.0"^^xsd:float ; "2017-03-18"^^xsd:date ; "RADAR"@en ; "SPECTRAL/ENGINEERING"@en ; "NONE"@en ; "RADAR CROSS-SECTION"@en , "RADAR REFLECTIVITY"@en ; "1.0"^^xsd:float ; "0.0"^^xsd:float . a base: ; owl:versionInfo "2020-09-16T19:36:14.589Z" , "2020-09-16T19:36:14.535Z" ; "This Level 1 (L1) dataset contains the Version 2.1 geo-located Delay Doppler Maps (DDMs) calibrated into Power Received (Watts) and Bistatic Radar Cross Section (BRCS) expressed in units of m2 from the Delay Doppler Mapping Instrument aboard the CYGNSS satellite constellation.

Here is a summary of improvements that reflect the quality of the Version 2.1 data release: 1) data is now available when the CYGNSS satellites are rolled away from nadir during orbital high beta-angle periods, resulting in a significant amount of additional data; 2) correction to coordinate frames result in more accurate estimates of receiver antenna gain at the specular point; 3) improved calibration for analog-to-digital conversion results in better consistency between CYGNSS satellites measurements at nearly the same location and time; 4) improved GPS EIRP and transmit antenna pattern calibration results in significantly reduced PRN-dependence in the observables; 5) improved estimation of the location of the specular point within the DDM; 6) an altitude-dependent scattering area is used to normalize the scattering cross section (v2.0 used a simpler scattering area model that varied with incidence and azimuth angles but not altitude); 7) corrections added for noise floor-dependent biases in scattering cross section and leading edge slope of delay waveform observed in the v2.0 data.

This dataset contains estimates of static field geopotential of the Earth, derived from the Gravity Recovery and Climate Experiment (GRACE) mission measurements, produced by the Center for Space Research (CSR) at University of Texas at Austin. The data are in spherical harmonics averaged over approximately a month. The primary objective of the GRACE mission is to obtain accurate estimates of the mean and time-variable components of the gravity field variations. This objective is achieved by making continuous measurements of the change in distance between twin spacecraft, co-orbiting in about 500 km altitude, near circular, polar orbit, spaced approximately 200 km apart, using a microwave ranging system. In addition to these range change, the non-gravitional forces are measured on each satellite using a high accuracy electrostatic, room-temperature accelerometer. The satellite orientation and position (and timing) are precisely measured using twin star cameras and a GPS receiver, respectively. Spatial and temporal variations in the gravity field affect the orbits (or trajectories) of the twin spacecraft differently. These differences are manifested as changes in the distance between the spacecraft, as they orbit the Earth. This change in distance is reflected in the time-of-flight of microwave signals transmitted and received nearly simultaneously between the two spacecraft. The change in this time of fight is continuously measured by tracking the phase of the microwave carrier signals. The so called dual-one-way range change measurements can be reconstructed from these phase measurements. This range change (or its numerically derived derivatives), along with other mission and ancillary data, is subsequently analyzed to extract the parameters of an Earth gravity field model."@en ; "none"@en ; "EARTH SCIENCE"@en ; "2020-09-16"^^xsd:date ; "Dataset Creation via Metadata Tool"@en ; "https://podaac.jpl.nasa.gov/" ; "English"@en ; "GRACE"@en ; "CSR"@en ; "2018-05-10"^^xsd:date ; "JPL"@en ; "GRACE Monthly Geopotential Spherical Harmonic Coefficients CSR (GSM)"@en ; "GRACE_GSM_L2_GRAV_CSR_RL06"@en ; "180.0"^^xsd:float ; "podaac@podaac.jpl.nasa.gov"@en ; "PODAAC-GRGSM-20C06" ; "GRACE FIELD GEOPOTENTIAL COEFFICIENTS CSR RELEASE 6.0"@en ; ""@en ; "Geoscientific Information"@en , "Oceans"@en ; "2018-04-26"^^xsd:date ; ""@en ; "Geographic Region"@en ; "Global"@en ; "GRACE K-Band Ranging System"@en , "Star Camera Assembly"@en , "Gravity Recovery and Climate Experiment"@en , ""@en , "GRACE SuperSTAR Accelerometer"@en ; "CEOS IDN DIF"@en ; "9.8"^^xsd:float ; "88.0"^^xsd:float ; "https://podaac-tools.jpl.nasa.gov/drive/files/allData/grace/docs/" ; "GRACE/CSR"@en ; "Data Center Contact"@en ; "GRACE KBR"@en , ""@en , "GRACE SCA"@en , "GRACE"@en , "GRACE ACC"@en , "USA/NASA"@en ; "-88.0"^^xsd:float ; "2002-04-05"^^xsd:date ; "2017-06-30"^^xsd:date ; "GRAVITY/GRAVITATIONAL FIELD"@en , "OCEAN PRESSURE"@en ; "SOLID EARTH"@en , "OCEANS"@en ; "none"@en ; "GRAVITY"@en , "WATER PRESSURE"@en ; "6.0"^^xsd:float ; "-180.0"^^xsd:float . a base: ; owl:versionInfo "2020-09-16T19:36:14.504Z" , "2020-09-16T19:36:14.570Z" ; "The monthly ocean bottom pressure anomaly grids are given as equivalent water thickness changes derived from GRACE & GRACE-FO time-variable gravity observations during the specified timespan, and relative to the specified time-mean reference period.

It is a product of the European Organization for the Exploitation of Meteorological Satellites (EUMETSAT) Ocean and Sea Ice Satellite Application Facility (OSI SAF) provided through the Royal Netherlands Meteorological Institute (KNMI). This coastal dataset differs from the standard 12.5 and 25 km datasets in that it utilizes a spatial box filter (rather than the Hamming filter) to generate a spatial average of the Sigma-0 retrievals from the Level 1B dataset; all full resolution Sigma-0 retrievals within a 15 km radius of the wind vector cell centroid are used in the averaging. Since the full resolution L1B Sigma-0 retrievals are used, all non-sea retrievals are discarded prior to the Sigma-0 averaging. Each box average Sigma-0 is then used to compute the wind vector cell using the same CMOD7.n geophysical model function as in the standard OSI SAF ASCAT wind vector datasets. With this enhanced coastal retrieval, winds can be computed as close to ~15 km from the coast. Each file is provided in netCDF version 3 format, and contains one full orbit derived from 3-minute orbit granules. Latency is approximately 2 hours from the latest measurement. The beginning of the orbit is defined by the first wind vector cell measurement within the first 3-minute orbit granule that starts north of the Equator in the ascending node. ASCAT is a C-band dual swath fan beam radar scatterometer providing two independent swaths of backscatter retrievals in sun-synchronous polar orbit aboard the MetOp-C platform.

Higher resolution is achieved through a slice composite technique in which high resolution slice measurements from L1B data are composited into a 12.5 km wind vector cell. Version 3.1 processing begins with the same L1B (time-ordered backscatter) data as used in the previous Version 3.0 processing. Version 3.1 improves upon the previous Version 3.0 processing by incorporating enhanced coastal processing using a Land Contamination Ratio (LCR) method with a fixed threshold. The 12.5 km binning resolution combined with the LCR processing enables this dataset to provide wind vector retrievals with approximately half the coastal gap as compared to the Version 3.0 12.5 km L2B dataset. The geophysical model function used to produce the wind vector cell retrievals remains unchanged between Version 3.0 and 3.1.

Average daily, weekly (8 day), monthly and annual skin SST products at are available at both 4.63 and 9.26 km spatial resolution. Aqua was launched by NASA on May 4, 2002, into a sun synchronous, polar orbit with a daylight ascending node at 13:30, formation flying in the A-train with other Earth Observation Satellites (EOS), to study the global dynamics of the Earth atmosphere, land and oceans. MODIS captures data in 36 spectral bands at a variety of spatial resolutions. Two SST products can be present in these files. The first is a skin SST produced for both day and night (NSST) observations, derived from the long wave IR 11 and 12 micron wavelength channels, using a modified nonlinear SST algorithm intended to provide continuity of SST derived from heritage and current NASA sensors. At night, a second SST product is generated using the mid-infrared 3.95 and 4.05 micron wavelength channels which are unique to MODIS; the SST derived from these measurements is identified as SST4. The SST4 product has lower uncertainty, but due to sun glint can only be used at night. To generate the L3 products the L2 pixels are binned into an integerized sinusoidal area grid (ISEAG) and mapped into an equidistant cylindrical (also known as Platte Carre projection. Additional projection detailed can be found at https://oceancolor.gsfc.nasa.gov/docs/format/The NASA MODIS L3 SST data products are generated by the NASA Ocean Biology Processing Group (OBPG) and Peter Minnett and his team at the Rosenstiel School of Marine and Atmospheric Science (RSMAS) are responsible for sea surface temperature algorithm development, error statistics and quality flagging.

This dataset contains estimates of static field geopotential of the Earth, derived from the Gravity Recovery and Climate Experiment (GRACE) mission measurements, produced by the NASA Jet Propulsion Laboratory (JPL). The data are in spherical harmonics averaged over approximately a month. The primary objective of the GRACE mission is to obtain accurate estimates of the mean and time-variable components of the gravity field variations. This objective is achieved by making continuous measurements of the change in distance between twin spacecraft, co-orbiting in about 500 km altitude, near circular, polar orbit, spaced approximately 200 km apart, using a microwave ranging system. In addition to these range change, the non-gravitional forces are measured on each satellite using a high accuracy electrostatic, room-temperature accelerometer. The satellite orientation and position (and timing) are precisely measured using twin star cameras and a GPS receiver, respectively. Spatial and temporal variations in the gravity field affect the orbits (or trajectories) of the twin spacecraft differently. These differences are manifested as changes in the distance between the spacecraft, as they orbit the Earth. This change in distance is reflected in the time-of-flight of microwave signals transmitted and received nearly simultaneously between the two spacecraft. The change in this time of fight is continuously measured by tracking the phase of the microwave carrier signals. The so called dual-one-way range change measurements can be reconstructed from these phase measurements. This range change (or its numerically derived derivatives), along with other mission and ancillary data, is subsequently analyzed to extract the parameters of an Earth gravity field model."@en ; "none"@en ; "EARTH SCIENCE"@en ; "2020-09-16"^^xsd:date ; "Dataset Creation via Metadata Tool"@en ; "https://podaac.jpl.nasa.gov/" ; "English"@en ; "GRACE"@en ; "JPL"@en ; "2018-07-05"^^xsd:date ; "JPL PO.DAAC"@en ; "GRACE Monthly Geopotential Spherical Harmonic Coefficients JPL (GSM)"@en ; "GRACE_GSM_L2_GRAV_JPL_RL06"@en ; "180.0"^^xsd:float ; "podaac@podaac.jpl.nasa.gov"@en ; "PODAAC-GRGSM-20J06" ; "GRACE FIELD GEOPOTENTIAL COEFFICIENTS JPL RELEASE 6.0"@en ; ""@en ; "Geoscientific Information"@en , "Oceans"@en ; "2018-06-11"^^xsd:date ; ""@en ; "Geographic Region"@en ; "Global"@en ; "Star Camera Assembly"@en , "Gravity Recovery and Climate Experiment"@en , ""@en , "GRACE K-Band Ranging System"@en , "GRACE SuperSTAR Accelerometer"@en ; "CEOS IDN DIF"@en ; "9.8"^^xsd:float ; "88.0"^^xsd:float ; "https://podaac-tools.jpl.nasa.gov/drive/files/allData/grace/docs/" ; "GRACE/JPL"@en ; "Data Center Contact"@en ; "GRACE"@en , ""@en , "GRACE ACC"@en , "USA/NASA"@en , "GRACE KBR"@en , "GRACE SCA"@en ; "-88.0"^^xsd:float ; "2002-04-04"^^xsd:date ; "2017-06-30"^^xsd:date ; "GRAVITY/GRAVITATIONAL FIELD"@en , "OCEAN PRESSURE"@en ; "SOLID EARTH"@en , "OCEANS"@en ; "none"@en ; "GRAVITY"@en , "WATER PRESSURE"@en ; "6.0"^^xsd:float ; "-180.0"^^xsd:float . a base: ; owl:versionInfo "2020-09-16T19:36:14.267Z" ; "A Group for High Resolution Sea Surface Temperature (GHRSST) global Level 4 sea surface temperature analysis produced daily on a 0.25 degree grid at the NOAA National Climatic Data Center.

Version 1.3 is intended as a replacement and continuation of the Version 1.2 data forward from orbital revolution number 7873, corresponding to 11 February 2016; on 11 Feb 2016, RapidScat entered it's 3rd low signal to noise ratio (SNR) state and the initial calibration of low SNR 3 was preliminary during the Version 1.2 release. The fundamental difference between Version 1.3 and the previous Version 1.2 datasets is that the L1B sigma-0 has been re-calibrated during the periods of low SNR states 3 and 4 using re-pointed QuikSCAT data. The pulse \"egg\" represents the complete footprint of the pulse, which has a spatial geometry of approximately 25 km by 35 km. There are 8 slices that constitute the range-binned components of a pulse each of which has a spatial geometry of approximately 25 km by 7 km. The orientation of the long dimension of the slices varies with the rotation of the antenna and thus does not align with the along/across track orientation of the wind vector grid in the L2B/L2A products. Data are provided in single-orbit files in HDF-4 format. RapidScat is a Ku-band dual beam circular rotating scatterometer retaining much of the same hardware and functionality of QuikSCAT, with exception of the antenna sub-system and digital interface to the ISS Columbus module, which is where RapidScat is mounted. The NASA mission is officially referred to as ISS-RapidScat. Unlike QuikSCAT, ISS-RapidScat is not in sun-synchronous orbit, and flies at roughly half the altitude with a low inclination angle that restricts data coverage to the tropics and mid-latitude regions; the extent of latitudinal coverage stretches from approximately 61 degrees North to 61 degrees South. Furthermore, there is no consistent local time of day retrieval. Caution: this dataset is intended for expert use only.

This radiometer is well-calibrated and contains the lower frequency channels required for SST retrievals. The radiometer operates in 5 discrete bands: 6.8, 10.7, 18.7, 23.8 and 37.0 GHz. The 10.7, 18.7 and 37.0 GHz bands are fully polarimetric whereas the 6.8 and 23.8 GHz bands have only dual polarization. The feedhorns of each frequency band trace out different arcs along the bench, therefore the Earth Incidence Angles (EIA) are different for each frequency band. Unlike previous radiometers, the WindSat sensor takes observations during both the forward and aft looking scans. This makes the WindSat geometry of the earth view swath quite different and significantly more complicated than the other passive microwave sensors. The Remote Sensing Systems (RSS, or REMSS) WindSat dataset is the only one available that uses both the fore and aft look directions which results in a wider swath and more complicated swath geometry visible in the provided maps. RSS produces these SST data for the Group for High Resolution Sea Surface Temperature (GHRSST) Project. In the data processing chain, a first stage produces a near-real-time (NRT) dataset (identified with a \"rt\" within the file name) which is made as available as soon as possible.

This dataset provides nominal 4.45 km (pixel resolution at reference latitude 70 N) gridded fields that classify First-Year (FY) and Multi-Year (MY) sea ice using SeaWinds on QuikSCAT scatterometer observations on a daily basis from 20 June 2002 through 23 November 2009. It is unique from other sea ice classification datasets primarily due to its utilization of passive microwave AMSR-E data to provide the initial ocean/ice masking edge and the use of a seasonal threshold for FY and MY sea ice classification from only SeaWinds data.The dataset is derived from daily gridded QuikSCAT vertically polarized (V-pol) egg backscatter data from the SCP, which is made available at the PO.DAAC: http://podaac.jpl.nasa.gov/dataset/QUIKSCAT_BYU_L3_OW_SIGMA0_ENHANCED . A seasonally varying threshold was derived by Swan and Long (2012) and used to discriminate between FY and MY sea ice based on QuikSCAT V-pol egg backscatter. The sea ice mask was derived by applying threshold constraints to the SCP AMSR-E 6 GHz images, which are made available by the BYU SCP: http://www.scp.byu.edu/data/AMSRE/SIR/AMSRE_sir.html . The data is provided in a CF-compliant, netCDF version 3 format. Further details on the algorithms and validation are described in further detail by Swan and Long (2012). The dataset, software readers and user guide documentation may all be accessed in PO.DAAC Drive at https://podaac-tools.jpl.nasa.gov/drive/files/allData/quikscat/preview/L3/byu_scp/sea_ice_age/arctic/ .

The CCMP datasets combine cross-calibrated satellite winds obtained from Remote Sensing Systems (REMSS) using a Variational Analysis Method (VAM) to produce a high-resolution (0.25 degree) gridded analysis. Wind directions from the resulting analysis are assigned to the location and time of the satellite-derived wind speed observations to create this value added dataset. The CCMP data set includes cross-calibrated satellite winds derived from SSM/I, SSMIS, AMSR-E, TRMM TMI, QuikSCAT, SeaWinds, WindSat and other satellite instruments as they become available from REMSS. REMSS uses a cross-calibrated sea-surface emissivity model function which improves the consistency between wind speed retrievals from microwave radiometers (i.e., SSM/I, SSMIS, AMSR, TMI, WindSat) and those from scatterometers (i.e., QuikSCAT and SeaWinds). The VAM combines these data with in situ measurements and a starting estimate (first guess) of the wind field. The European Center for Medium-Range Weather Forecasts (ECMWF) ERA-40 Reanalysis is used as the first-guess from 1987 to 1998. The ECMWF Operational analysis is used from January 1999 onward. All wind observations and analysis fields are referenced to a height of 10 meters. The ERA-40 can be obtained from the Computation and Information Systems Laboratory (CISL) at the National Center for Atmospheric Research (NCAR): http://rda.ucar.edu/datasets/ds117.0/. The ECMWF Operational analysis can also be obtained from CISL at NCAR: http://rda.ucar.edu/datasets/ds111.1/. Three products are distributed to complete the CCMP dataset series. L3.0 product contains high-resolution analyses every 6-hours. These data are then time averaged over monthly and 5-day periods to derive the L3.5 product. Directions from the L3.0 product are then assigned to the time and location of the passive microwave satellite wind speed observations to derive the L2.5 product. All datasets are distributed on a 0.25 degree cylindrical coordinate grid. This dataset is one in a series of First-Look (FLK) CCMP datasets and is a continuation and expansion of the SSM/I surface wind velocity project that began under the NASA Pathfinder Program. Refinements and upgrades to the FLK version will be incorporated under a new release (date to be determined) known as Late-look (LLK) and may include additional satellite datasets. All satellite surface wind data are obtained from REMSS under the DISCOVER project: Distributed Information Services: Climate/Ocean Products and Visualizations for Earth Research (http://www.discover-earth.org/index.html). The CCMP project is the result of an investigation funded by the NASA Making Earth Science data records for Use in Research Environments (MEaSUREs) program (http://community.eosdis.nasa.gov/measures/). In accordance with the MEaSUREs program, the CCMP datasets are also known as Earth System Data Records (ESDRs). In collaboration with private and government institutions, a team led by Dr. Robert Atlas (PI; proposal originally solicited by REASoN, and currently funded by MEaSURES) has created the CCMP project to provide multi-instrument ocean surface wind velocity ESDRs, with wide ranging research applications in meteorology and oceanography."@en ; "NONE"@en ; "EARTH SCIENCE"@en ; "2020-09-16"^^xsd:date ; "Dataset Creation via Metadata Tool"@en ; "https://podaac.jpl.nasa.gov/" ; "English"@en ; "NASA/GSFC/NOAA"@en ; "PO.DAAC"@en ; "2011-08-04"^^xsd:date ; "PO.DAAC"@en ; "Cross-Calibrated Multi-Platform Ocean Surface Wind Vector L2.5 First-Look WindSat Microwave Analyses"@en ; "Cross-Calibrated Multi-Platform Ocean Surface Wind Vector L2.5 First-Look WindSat Microwave Analyses"@en ; "360.0"^^xsd:float ; "podaac@podaac.jpl.nasa.gov"@en ; "PODAAC-CCF25-01WSC" ; "Cross-Calibrated Multi-Platform Ocean Surface Wind Vector L2.5 First-Look WindSat Microwave Analyses"@en ; ""@en ; "Geoscientific Information"@en , "Oceans"@en ; "2011-08-05"^^xsd:date ; ""@en ; "0.25"^^xsd:float ; "Geographic Region"@en ; "Global"@en ; "Making Earth Science Data Records for Use in Research Environments"@en , "WindSat"@en , ""@en , "Coriolis"@en ; "0.25"^^xsd:float ; "CEOS IDN DIF"@en ; "9.8"^^xsd:float ; "89.875"^^xsd:float ; "https://podaac-tools.jpl.nasa.gov/drive/files/allData/ccmp/L2.5/docs/ccmp_users_guide.pdf" ; "NASA/GSFC/NOAA"@en ; "Data Center Contact"@en ; ""@en , "WINDSAT"@en , "CORIOLIS"@en , "USA/NASA"@en , "MEaSUREs"@en ; "-89.875"^^xsd:float ; "2010-01-01"^^xsd:date ; "2011-12-31"^^xsd:date ; "12 Hour"@en ; "OCEAN WINDS"@en ; "OCEANS"@en ; "NONE"@en ; "SURFACE WINDS"@en ; "1.0"^^xsd:float ; "0.0"^^xsd:float . a base: ; owl:versionInfo "2020-09-16T19:36:14.575Z" , "2020-09-16T19:36:14.518Z" ; "The Moderate-resolution Imaging Spectroradiometer (MODIS) is a scientific instrument (radiometer) on board the NASA Terra and Aqua satellite platforms, launched in 1999 and 2002 respectively to study global dynamics of the Earths atmosphere, land, ice and oceans.

Aqua was launched by NASA on May 4, 2002, into a sun synchronous, polar orbit with a daylight ascending node at 13:30, formation flying in the A-train with other Earth Observation Satellites (EOS), to study the global dynamics of the Earth atmosphere, land and oceans. MODIS captures data in 36 spectral bands at a variety of spatial resolutions. Two SST products can be present in these files. The first is a skin SST produced for both day and night (NSST) observations, derived from the long wave IR 11 and 12 micron wavelength channels, using a modified nonlinear SST algorithm intended to provide continuity of SST derived from heritage and current NASA sensors. At night, a second SST product is generated using the mid-infrared 3.95 and 4.05 micron wavelength channels which are unique to MODIS; the SST derived from these measurements is identified as SST4. The SST4 product has lower uncertainty, but due to sun glint can only be used at night. To generate the L3 products the L2 pixels are binned into an integerized sinusoidal area grid (ISEAG) and mapped into an equidistant cylindrical (also known as Platte Carre projection.

The project is comprised of two field campaigns and a series of cruises in regions of the Atlantic and Pacific Oceans exhibiting salinity extremes. SPURS employs a suite of state-of-the-art in-situ sampling technologies that, combined with remotely sensed salinity fields from the Aquarius/SAC-D, SMAP and SMOS satellites, provide a detailed characterization of salinity structure over a continuum of spatio-temporal scales. The SPURS-2 campaign involved two month-long cruises by the R/V Revelle in August 2016 and October 2017 combined with complementary sampling on a more continuous basis over this period by the schooner Lady Amber. Focused around a central mooring located near 10N,125W, the objective of SPURS-2 was to study the dynamics of the rainfall-dominated surface ocean at the western edge of the eastern Pacific fresh pool subject to high seasonal variability and strong zonal flows associated with the North Equatorial Current and Countercurrent. A Waveglider is an autonomous platform propelled by the conversion of ocean wave energy into forward thrust and employing solar panels to power instrumentation. For SPURS-2, sensors included a CTD at the near-surface and another at 6 m depth, providing continuous salinity and temperature observations plus air temperature and wind measurements. Three wavegliders (ASL22, 32, 42) were deployed from the Revelle in August 2016 and again in November 2017 before final retrieval at the conclusion on the second cruise.

Aqua was launched by NASA on May 4, 2002, into a sun synchronous, polar orbit with a daylight ascending node at 13:30, formation flying in the A-train with other Earth Observation Satellites (EOS), to study the global dynamics of the Earth atmosphere, land and oceans. MODIS captures data in 36 spectral bands at a variety of spatial resolutions. Two SST products can be present in these files. The first is a skin SST produced for both day and night (NSST) observations, derived from the long wave IR 11 and 12 micron wavelength channels, using a modified nonlinear SST algorithm intended to provide continuity of SST derived from heritage and current NASA sensors. At night, a second SST product is generated using the mid-infrared 3.95 and 4.05 micron wavelength channels which are unique to MODIS; the SST derived from these measurements is identified as SST4. The SST4 product has lower uncertainty, but due to sun glint can only be used at night. To generate the L3 products the L2 pixels are binned into an integerized sinusoidal area grid (ISEAG) and mapped into an equidistant cylindrical (also known as Platte Carre projection.

Version 1.2 is intended as a replacement and continuation of the Version 1.1 data forward from orbital revolution number 5127, corresponding to 19 August 2015; the overlapping time period starting on 19 August 2015 corresponds to the first time period of the recorded low signal-to-noise ratio (SNR). This Version 1.2 dataset differs from the previous Version 1.1 dataset as follows: 1) L1B sigma-0 has been re-calibrated during the periods of low signal-to-noise ratio (SNR) and 2) during low SNR periods the L1B sigma-0 calibration is determined using re-pointed L1B QuikSCAT data. Due to the circular scan of the SeaWinds instrument the expected number of Sigma-0 cells per WVC is not constant. To minimize the L2A data volume, the Sigma-0 cell data are stored as \"lists\" for each WVC row, with each list indexed by a \"cell_index\" array to indicate the cross-track WVC membership of the data. Each cell is then checked for land or ice and flagged accordingly. Attenuation corrections for each Sigma-0 measurement are also provided. Data are provided in single-orbit files in HDF-4 format. RapidScat is a Ku-band dual beam circular rotating scatterometer retaining much of the same hardware and functionality of QuikSCAT, with exception of the antenna sub-system and digital interface to the International Space Station (ISS) Columbus module, which is where RapidScat is mounted. The NASA mission is officially referred to as ISS-RapidScat. Unlike QuikSCAT, ISS-RapidScat is not in sun-synchronous orbit, and flies at roughly half the altitude with a low inclination angle that restricts data coverage to the tropics and mid-latitude regions; the extent of latitudinal coverage stretches from approximately 56 degrees North to 56 degrees South.

CAP Level 3 standard mapped image products contain gridded 1 degree spatial resolution salinity and wind speed data averaged over 7 day and monthly time scales. This particular dataset is the 7-Day running mean wind speed V5.0 Aquarius CAP product. CAP is a P.I. produced dataset developed and provided by JPL. The CAP algorithm utilizes data from both the onboard radiometer and scatterometer to simultaneously retrieve salinity, wind speed and direction by minimizing the sum of squared differences between model and observations. The main improvements in CAP V5.0 relative to the previous version include: updates to the Geophysical Model Functions to 4th order harmonics with the inclusion of sea surface temperature (SST) and stability at air-sea interface effects; use of the Canadian Meteorological Center (CMC) SST product as the new source ancillary sea surface temperature data in place of NOAA OI SST. The Aquarius instrument is onboard the AQUARIUS/SAC-D satellite, a collaborative effort between NASA and the Argentinian Space Agency Comision Nacional de Actividades Espaciales (CONAE). The instrument consists of three radiometers in push broom alignment at incidence angles of 29, 38, and 46 degrees incidence angles relative to the shadow side of the orbit. Footprints for the beams are: 76 km (along-track) x 94 km (cross-track), 84 km x 120 km and 96km x 156 km, yielding a total cross-track swath of 370 km.

The MetOp satellite program is a European undertaking providing weather data services for monitoring climate and improving weather forecasts. It was jointly established by the European Space Agency (ESA) and the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) with a contribution by the US National Oceanic and Atmospheric Administration (NOAA) of an AVHRR sensor identical to those flying on the family of Polar Orbiting Environmental Satellites (POES). AVHRR instruments measure the radiance of the Earth in 5 (or 6) relatively wide spectral bands. The first two are centered around the red (0.6 micrometer) and near-infrared (0.9 micrometer) regions, the third one is located around 3.5 micrometer, and the last two sample the emitted thermal radiation, around 11 and 12 micrometers, respectively. The legacy 5 band instrument is known as AVHRR/2 while the more recent version, the AVHRR/3 (first carried on the NOAA-15 platform), acquires data in a 6th channel located at 1.6 micrometer. Typically the 11 and 12 micron channels are used to derive SST sometimes in combination with the 3.5 micron channel. The MetOp-A platform is sun synchronous generally viewing the same earth location twice a day (latitude dependent) due to the relatively large AVHRR swath of approximately 2400 km. The highest ground resolution that can be obtained from the current AVHRR instruments is 1.1 km at nadir. This particular dataset is produced from Global Area Coverage (GAC) data that are derived from an on-board sample averaging of the full resolution global AVHRR data. Four out of every five samples along the scan line are used to compute on average value and the data from only every third scan line are processed, yielding an effective 4 km resolution at nadir. Further binning and averaging of these pixels results in a final dataset resolution of 8.8 km."@en ; "None"@en ; "EARTH SCIENCE"@en ; "2020-09-16"^^xsd:date ; "Dataset Creation via Metadata Tool"@en ; "https://podaac.jpl.nasa.gov/" ; "English"@en ; "Naval Oceanographic Office"@en ; "Naval Oceanographic Office"@en ; "2014-10-27"^^xsd:date ; "Stennis Space Center, MS, USA"@en ; "GHRSST Level 2P Global 1m Sea Surface Temperature from the Advanced Very High Resolution Radiometer (AVHRR) on the MetOp-B satellite produced by NAVO"@en ; "METOP-A AVHRR GAC L2P swath SST data set"@en ; "180.0"^^xsd:float ; "podaac@podaac.jpl.nasa.gov"@en ; "PODAAC-GHMTB-2PN02" ; "GHRSST Level 2P Global 1m Sea Surface Temperature from the Advanced Very High Resolution Radiometer (AVHRR) on the MetOp-B satellite produced by NAVO"@en ; ""@en ; "Oceans"@en , "Geoscientific Information"@en ; "2017-04-28"^^xsd:date ; ""@en ; "Geographic Region"@en ; "Global"@en ; "Advanced Very High Resolution Radiometer-3"@en , "Meteorological Operational Satellite - B"@en , "Group for High Resolution Sea Surface Temperature"@en , ""@en ; "CEOS IDN DIF"@en ; "9.8"^^xsd:float ; "80.0"^^xsd:float ; "" ; "Naval Oceanographic Office"@en ; "Data Center Contact"@en ; "USA/NASA"@en , ""@en , "METOP-B"@en , "AVHRR-3"@en , "GHRSST"@en ; "-70.0"^^xsd:float ; "2013-09-24"^^xsd:date ; "2020-06-22"^^xsd:date ; "OCEAN TEMPERATURE"@en ; "OCEANS"@en ; "None"@en ; "SEA SURFACE TEMPERATURE"@en ; "1.0"^^xsd:float ; "-180.0"^^xsd:float . a base: ; owl:versionInfo "2020-09-16T19:36:14.503Z" ; "Aquarius Level 3 ocean surface wind speed standard mapped image data contains gridded 1 degree spatial resolution wind speed data averaged over daily,7 day, monthly, and seasonal time scales.

Average daily, weekly (8 day), monthly and annual skin SST products are available at both 4.63 and 9.26 km spatial resolution. Terra was launched by NASA on December 18, 1999, into a sun synchronous, polar orbit with a daylight descending node at 10:30 am, to study the global dynamics of the Earth atmosphere, land and oceans. The MODIS captures data in 36 spectral bands at a variety of spatial resolutions. Two SST products can be present in these files. The first is a skin SST produced for both day and night observations, derived from the long wave IR 11 and 12 micron wavelength channels, using a modified nonlinear SST algorithm intended to provide continuity with SST derived from heritage and current NASA sensors. At night, a second SST product is produced using the mid-infrared 3.95 and 4.05 micron channels which are unique to MODIS; the SST derived from these measurements is identified as SST4. The SST4 product has lower uncertainty, but due to sun glint can only be produced at night. To generate the L3 products the L2 pixels are binned into an integerized sinusoidal area grid (ISEAG) and mapped into an equidistant cylindrical (also known as Platte Carre) projection. Additional projection detailed can be found at https://oceancolor.gsfc.nasa.gov/docs/format/The NASA MODIS L3 SST data products are generated by the NASA Ocean Biology Processing Group (OBPG) Peter Minnett and his team at the Rosenstiel School of Marine and Atmospheric Science (RSMAS) are responsible for sea surface temperature algorithm development, error statistics and quality flagging.

The GPM mission is a joint effort between NASA, the Japan Aerospace Exploration Agency (JAXA) and other international partners. In march 2005, NASA has chosen the Ball Aerospace and Technologies Corp., Boulder, Colorado to build the GMI instrument on the continued success of the Tropical Rainfall Measuring Mission (TRMM) satellite by expanding current coverage of precipitation from the tropics to the entire world. GMI is a dual-polarization, multi-channel, conical-scanning, passive microwave radiometer with frequent revisit times. One of the primary differences between GPM and other satellites with microwave radiometers is the orbit, which is inclined 65 degrees, allowing a full sampling of all local Earth times repeated approximately every 2 weeks. The GPM platform undergoes yaw maneuvers approximately every 40 days to compensate for the sun's changing position and prevent the side of the spacecraft facing the sun from overheating. Today, the GMI instrument plays an essential role in the worldwide measurement of precipitation and environmental forecasting. Sea Surface Temperature (SST) is one of its major products. The GMI data from the Remote Sensing System (REMSS) have been produced using an updated RTM, Version-8. The V8 brightness temperatures from GMI are slightly different from the V7 brightness temperatures; The SST datasets are available in near-real time (NRT) as they arrive, with a delay of about 3 to 6 hours, including the Daily, 3-Day, Weekly, and Monthly time series products."@en ; "None"@en ; "EARTH SCIENCE"@en ; "2020-09-16"^^xsd:date ; "Dataset Creation via Metadata Tool"@en ; "https://podaac.jpl.nasa.gov/" ; "English"@en ; "Remote Sensing Systems"@en ; "Remote Sensing Systems"@en ; "2017-11-30"^^xsd:date ; "Santa Rosa, CA, USA"@en ; "GHRSST Level 3U Global Subskin Sea Surface Temperature from GMI onboard GPM satellite"@en ; "GMI 25km gridded SST data set"@en ; "180.0"^^xsd:float ; "podaac@podaac.jpl.nasa.gov"@en ; "PODAAC-GHGMI-3UR8A" ; "GHRSST Level 3U Global Subskin Sea Surface Temperature from GMI onboard GPM satellite"@en ; ""@en ; "Oceans"@en , "Geoscientific Information"@en ; "2017-06-13"^^xsd:date ; ""@en ; "0.25"^^xsd:float ; "Geographic Region"@en ; "Global"@en ; "Global Precipitation Measurement Core Observatory"@en , ""@en , "GPM Microwave Imager"@en , "Group for High Resolution Sea Surface Temperature"@en ; "0.25"^^xsd:float ; "0.0"^^xsd:float ; "0.0"^^xsd:float ; "CEOS IDN DIF"@en ; "9.8"^^xsd:float ; "0.0"^^xsd:float ; "0.0"^^xsd:float ; "90.0"^^xsd:float ; "http://www.remss.com" ; "Remote Sensing Systems"@en ; "Data Center Contact"@en ; "USA/NASA"@en , "GMI"@en , ""@en , "GPM"@en , "GHRSST"@en ; "-90.0"^^xsd:float ; "2014-03-04"^^xsd:date ; "OCEAN TEMPERATURE"@en ; "OCEANS"@en ; "None"@en ; "SEA SURFACE TEMPERATURE"@en ; "8.2a" ; "-180.0"^^xsd:float . a base: ; owl:versionInfo "2020-09-16T19:36:14.593Z" , "2020-09-16T19:36:14.544Z" ; "GDS2 Version -The Advanced Microwave Scanning Radiometer 2 (AMSR2) was launched on 18 May 2012, onboard the Golbal Change Observation Mission - Water (GCOM-W) satellite developed by the Japan Aerospace Exploration Agency (JAXA). The GCOM-W mission aims to establish the global and long-term observation system to collect data, which is needed to understand mechanisms of climate and water cycle variations, and demonstrate its utilization. AMSR2 onboard the first generation of the GCOM-W satellite will continue Aqua/AMSR-E observations of water vapor, cloud liquid water, precipitation, SST, sea surface wind speed, sea ice concentration, snow depth, and soil moisture. AMSR2 is a remote sensing instrument for measuring weak microwave emission from the surface and the atmosphere of the Earth. From about 700 km above the Earth, AMSR2 will provide us highly accurate measurements of the intensity of microwave emission and scattering. The antenna of AMSR2 rotates once per 1.5 seconds and obtains data over a 1450 km swath. This conical scan mechanism enables AMSR2 to acquire a set of daytime and nighttime data with more than 99% coverage of the Earth every 2 days. Remote Sensing Systems (RSS, or REMSS), providers of these SST data for the Group for High Resolution Sea Surface Temperature (GHRSST) Project, performs a detailed processing of AMSR-E instrument data in two stages. The first stage produces a near-real-time (NRT) product (identified by \"rt\" within the file name) which is made as available as soon as possible. This is generally within 3 hours of when the data are recorded. Although suitable for many timely uses the NRT products are not intended to be archive quality. \"Final\" data (currently identified by \"v8\" within the file name) are processed when RSS receives the atmospheric mode NCEP FNL analysis.

Incidence angles were varied in order to cross-calibrate the Oceansat-2 and RapidScat scatterometers and to extend the known Ku-band geophysical model function. The averaging of the L1B input data combined with the wind vector processing results are both contained in this product referred to hereafter as Level 1C (L1C). The fixed and repointed beam processing is relative to either the one corresponding to the vertically polarized \"outer\" beam or the other corresponding to the horizontally polarized \"inner\" beam. The Sigma-0 values from the fixed operating beam for each frame are averaged to a single value representing approximately 50 samples. The data points are land flagged, collocated with ECMWF surface winds, and have climatological nadir attenuations provided for the location and time of the data (not applied to the sigma0). The following enhancements have been applied in the Version 2 re-processing: 1) the GMF has been updated (QNS2016a) to make use of ECMWF nowcast 1x1 degree resolution wind direction information for the entire historical data record; 2) the new QNS2016a GMF leverages a calibration adjustment from Remote Sensing Systems (RSS) resulting in a consistently lower Normalized Radar Cross Section (NRCS or Sigma-0) measurements that establishes a Sigma-0 bias of -0.25 dB (-5.9% linear scale) compared to the L1C Version 1 data; 3) the new QNS2016a GMF also applies an azimuthal modulation that is decreased by several tenths of a dB (for Sigma-0) in variation with wind speed; this results in a more consistent wind speed retrieval comparison between \"non-spinning\" and \"spinning\" modes of the QuikSCAT instrument; 4) spacecraft attitude was re-estimated using slice data over multiple orbits as a replacement for lost echo-tracking capability during the \"non-spinning\" mode of the instrument; this new attitude estimation follows an unpublished manual technique that leverages the echo power of individual slice observations; since only a small subset of slice observations are analyzed, rapid variations in attitude are not captured; 5) continues data production beyond October 2016 through the end of mission on 30 August 2018. Retrieved wind directions are only slightly different from ECMWF values and should not be considered an independent measurement of wind direction. Retrieved wind speeds do not depend significantly on ECMWF speeds as evidenced by the fact that they agree closely with WindSAT polarimetric radiometer speeds whenever WindSAT and ECMWF disagree. The Sigma0 values have also been corrected for scan loss (due to the fact that the antenna does not scan) and for X-factor changes due to repointing."@en ; "None"@en ; "EARTH SCIENCE"@en ; "2020-09-16"^^xsd:date ; "Dataset Creation via Metadata Tool"@en ; "https://podaac.jpl.nasa.gov/" ; "English"@en ; "JPL"@en ; "PO.DAAC"@en ; "2019-02-13"^^xsd:date ; "PO.DAAC"@en ; "QuikSCAT Level 1C Averaged Sigma-0 and Winds from Non-spinning Antenna"@en ; "QuikSCAT Level 1C Averaged Sigma-0 and Winds from Non-spinning Antenna Version 2.0"@en ; "180.0"^^xsd:float ; "podaac@podaac.jpl.nasa.gov"@en ; "PODAAC-QSNON-L1CA2" ; "QuikSCAT Level 1C Averaged Sigma-0 and Winds from Non-spinning Antenna Version 2.0"@en ; ""@en ; "Oceans"@en , "Geoscientific Information"@en ; "2017-08-30"^^xsd:date ; ""@en ; "Geographic Region"@en ; "Global"@en ; "Quick Scatterometer"@en , ""@en , "QUIKSCAT"@en , "SeaWinds Scatterometer"@en ; "CEOS IDN DIF"@en ; "9.8"^^xsd:float ; "89.875"^^xsd:float ; "" ; "NASA/JPL/SeaPAC"@en ; "Data Center Contact"@en ; "SEAWINDS"@en , "USA/NASA"@en , ""@en , "QUIKSCAT"@en ; "-89.875"^^xsd:float ; "2010-07-16"^^xsd:date ; "2018-08-30"^^xsd:date ; "RADAR"@en , "OCEAN WINDS"@en ; "SPECTRAL/ENGINEERING"@en , "OCEANS"@en ; "None"@en ; "SIGMA NAUGHT"@en , "SURFACE WINDS"@en ; "2.0"^^xsd:float ; "-180.0"^^xsd:float . a base: ; owl:versionInfo "2020-09-16T19:36:14.588Z" , "2020-09-16T19:36:14.533Z" ; "A global Group for High Resolution Sea Surface Temperature (GHRSST) Level 2P data set containing multi-channel Sea Surface Temperature (SST) retrievals derived in real-time from the Advanced Very High Resolution Radiometer (AVHRR) level-1B data from the Meteorological Operational-A (MetOp-A) satellite.

The program was jointly established by the European Space Agency (ESA) and the European Organization for the Exploitation of Meteorological Satellites (EUMETSAT) with the US National Oceanic and Atmospheric Administration (NOAA) contributing the AVHRR sensor. AVHRR instruments measure the radiance of the Earth in 5 (or 6) relatively wide spectral bands. The first two are centered around the red (0.6 micron) and near-infrared (0.9 micron) regions, the third one is located around 4 (3.6) micron, and the last two sample the emitted thermal radiation, around 11 and 12 micron, respectively. The legacy 5 band instrument is known as AVHRR/2 while the more recent version, the AVHRR/3 (first carried on the NOAA-15 platform), acquires data in a 6th channel located at 1.6 micron. Typically, the 11 and 12 micron channels are used to derive SST sometimes in combination with the 3.5 micron channel. The swath of the AVHRR sensor is a relatively large 2400 km. All MetOp platforms are sun synchronous and generally view the same earth location twice a day (latitude dependent). The ground native resolution of the AVHRR instruments is approximately 1.1 km at nadir and degrades off nadir. This particular data set is produced from legacy Global Area Coverage (GAC) data that are derived from a sample averaging of the full resolution global AVHRR data. Four out of every five samples along the scan line are used to compute on average value and the data from only every third scan line are processed, yielding an effective 4 km spatial resolution at nadir. The v2.0 is the updated version from current v1.0 with extensive algorithm improvements and upgrades. The major improvements include: 1) Significant changes in contaminant/cloud detection; 2) Increased the spatial resolution from 9 km to 4 km; 3) Updated compliance with GDS2, ACDD 1.3, and CF 1.6; and 4) Removed the dependency on the High-resolution Infrared Radiation Sounder (HIRS) sensor (only available to MetOp-A/B), thus allowing for the consistent inter-calibration and the processing of MetOp-A/B/C data"@en ; "None"@en ; "EARTH SCIENCE"@en ; "2020-09-16"^^xsd:date ; "Dataset Creation via Metadata Tool"@en ; "https://podaac.jpl.nasa.gov/" ; "English"@en ; "Naval Oceanographic Office"@en ; "Naval Oceanographic Office"@en ; "2020-07-24"^^xsd:date ; "Stennis Space Center, MS, USA"@en ; "GHRSST Level 2P Global Bulk Sea Surface Temperature v2.0 from the Advanced Very High Resolution Radiometer (AVHRR) on the MetOp-A satellite produced by NAVO"@en ; "METOP-A AVHRR GAC L2P swath SST dataset v2.0"@en ; "180.0"^^xsd:float ; "podaac@podaac.jpl.nasa.gov"@en ; "PODAAC-GHMTA-2PN20" ; "GHRSST Level 2P Global Sea Surface Temperature v2.0 from the AVHRR on the MetOp-A satellite produced by NAVO"@en ; ""@en ; "Oceans"@en , "Geoscientific Information"@en ; "2020-06-11"^^xsd:date ; ""@en ; "0.04"^^xsd:float ; "Geographic Region"@en ; "Global"@en ; "Advanced Very High Resolution Radiometer-3"@en , ""@en , "Meteorological Operational Satellite - A"@en , "Group for High Resolution Sea Surface Temperature"@en ; "0.04"^^xsd:float ; "CEOS IDN DIF"@en ; "9.8"^^xsd:float ; "80.0"^^xsd:float ; "https://podaac.jpl.nasa.gov/GHRSST" ; "DOD/USNAVY/NAVOCEANO"@en ; "Data Center Contact"@en ; "AVHRR-3"@en , "METOP-A"@en , "USA/NASA"@en , "GHRSST"@en , ""@en ; "-70.0"^^xsd:float ; "2020-06-29"^^xsd:date ; "OCEAN TEMPERATURE"@en ; "OCEANS"@en ; "None"@en ; "SEA SURFACE TEMPERATURE"@en ; "2.0"^^xsd:float ; "-180.0"^^xsd:float . a base: ; owl:versionInfo "2020-09-16T19:36:14.477Z" ; "Aquarius Level 3 ancillary sea surface temperature (SST) standard mapped image data are the ancillary SST data used in the Aquarius calibration for salinity retrieval.

GOES-R series (which will also include -S, -T, and -U). G16 was launched on 19 Nov 2016 and initially placed in an interim position at 89.5-deg W, between GOES-East and -West. Upon completion of Cal/Val in Dec 2018, it was moved to its permanent position at 75.2-deg W, and declared NOAA operational GOES-East on 18 Dec 2018. NOAA is responsible for all GOES-R products, including Sea Surface Temperature (SST) from the Advanced Baseline Imager (ABI). The ABI offers vastly enhanced capabilities for SST retrievals, over the heritage GOES-I/P Imager, including five narrow bands (centered at 3.9, 8.4, 10.3, 11.2, and 12.3 um) out of 16 that can be used for SST, as well as accurate sensor calibration, image navigation and co-registration, spectral fidelity, and sophisticated pre-processing (geo-rectification, radiance equalization, and mapping). From altitude 35,800 km, G16/ABI can accurately map SST in a Full Disk (FD) area from 15-135-deg W and 60S-60N, with spatial resolution 2km at nadir (degrading to 15km at view zenith angle, 67-deg) and temporal sampling of 10min (15min prior to 2 Apr 2019). The Level 2 Preprocessed (L2P) SST product is derived at the native sensor resolution using NOAA Advanced Clear-Sky Processor for Ocean (ACSPO) system. ACSPO first processes every 10min FD data SSTs are derived from BTs using the ACSPO clear-sky mask (ACSM; Petrenko et al., 2010) and Non-Linear SST (NLSST) algorithm (Petrenko et al., 2014). Currently, only 4 longwave bands centered at 8.4, 10.3, 11.2, and 12.3 um are used (the 3.9 microns was initially excluded, to minimize possible discontinuities in the diurnal cycle). The regression is tuned against quality controlled in situ SSTs from drifting and tropical mooring buoys in the NOAA iQuam system (Xu and Ignatov, 2014). The 10-min FD data are subsequently collated in time, to produce 1-hr L2P product, with improved coverage, and reduced cloud leakages and image noise, compared to each individual 10min image. In the collated L2P, SSTs and BTs are only reported in clear-sky water pixels (defined as ocean, sea, lake or river, and up to 5 km inland) and fill values elsewhere. The L2P is reported in netCDF4 GHRSST Data Specification version 2 (GDS2) format, 24 granules per day, with a total data volume of 0.6GB/day. In addition to SST, ACSPO files also include sun-sensor geometry, four BTs in ABI bands 11 (8.4um), 13 (10.3um), 14 (11.2um), and 15 (12.3um) and two reflectances in bands 2 and 3 (0.64um and 0.86um; used for cloud identification). The l2p_flags layer includes day/night, land, ice, twilight, and glint flags. Other variables include NCEP wind speed and ACSPO SST minus reference SST (Canadian Met Centre 0.1deg L4 SST; available at https://podaac.jpl.nasa.gov/dataset/CMC0.1deg-CMC-L4-GLOB-v3.0).Pixel-level earth locations are not reported in the granules, as they remain unchanged from granule to granule. To obtain those, user has a choice of using a flat lat-lon file, or a Python script, both available at ftp://ftp.star.nesdis.noaa.gov/pub/socd4/coastwatch/sst/nrt/abi/nav/. Per GDS2 specifications, two additional Sensor-Specific Error Statistics layers (SSES bias and standard deviation) are reported in each pixel. The ACSPO VIIRS L2P product is monitored and validated against in situ data (Xu and Ignatov, 2014) using the Satellite Quality Monitor SQUAM (Dash et al, 2010), and BTs are validated against RTM simulation in MICROS (Liang and Ignatov, 2011). A reduced size (0.2GB/day), equal-angle gridded (0.02-deg resolution), ACSPO L3C product is also available at https://podaac.jpl.nasa.gov/dataset/ABI_G16-STAR-L3C-v2.70, where gridded L2P SSTs are reported, and BT layers omitted."@en ; "None"@en ; "EARTH SCIENCE"@en ; "2020-09-16"^^xsd:date ; "Dataset Creation via Metadata Tool"@en ; "https://podaac.jpl.nasa.gov/" ; "English"@en ; "NOAA/NESDIS USA, 5200 Auth Rd, Camp Springs, MD, 20746"@en ; "NOAA/NESDIS"@en ; "2019-05-15"^^xsd:date ; "Camp Springs, MD (USA)"@en ; "GHRSST NOAA/STAR GOES-16 ABI L2P America Region SST dataset in GDS2"@en ; "GHRSST Sea Surface Temperature 30W-135W and 65N-50S, at 0.036 degree resolution from GOES-16 ABI"@en ; "-15.0"^^xsd:float ; "podaac@podaac.jpl.nasa.gov"@en ; "PODAAC-GHG16-2PO27" ; "GHRSST NOAA/STAR GOES-16 ABI L2P America Region SST v2.70 dataset in GDS2"@en ; ""@en ; "Oceans"@en , "Geoscientific Information"@en ; "2019-03-28"^^xsd:date ; ""@en ; "0.018"^^xsd:float ; "Geographic Region"@en ; "Western Atlantic"@en ; "Advanced Baseline Imager (ABI)"@en , "Group for High Resolution Sea Surface Temperature"@en , ""@en , "Geostationary Operational Environmental Satellite 16"@en ; "0.018"^^xsd:float ; "0.0"^^xsd:float ; "CEOS IDN DIF"@en ; "9.8"^^xsd:float ; "0.0"^^xsd:float ; "0.0"^^xsd:float ; "59.0"^^xsd:float ; "" ; "NOAA/NESDIS"@en ; "Data Center Contact"@en ; ""@en , "GHRSST"@en , "GOES-16"@en , "USA/NASA"@en , "ABI"@en ; "-59.0"^^xsd:float ; "2017-12-15"^^xsd:date ; "60 Minute"@en ; "OCEAN TEMPERATURE"@en ; "OCEANS"@en ; "None"@en ; "SEA SURFACE TEMPERATURE"@en ; "2.7"^^xsd:float ; "-135.0"^^xsd:float . a base: ; owl:versionInfo "2020-09-16T19:36:14.498Z" ; "The Smith & Reynolds Extended Reconstructed Sea Surface Temperature (ERSST) Level 4 dataset provides a historical reconstruction of monthly global ocean surface temperatures and temperature anomalies over a 2 degree spatial grid since 1854 from in-situ observations based on a consistent statistical methodology that accounts for uneven sampling distributions over time and related observational biases.

Aqua was launched by NASA on May 4, 2002, into a sun synchronous, polar orbit with a daylight ascending node at 13:30, formation flying in the A-train with other Earth Observation Satellites (EOS), to study the global dynamics of the Earth atmosphere, land and oceans. MODIS captures data in 36 spectral bands at a variety of spatial resolutions. Two SST products can be present in these files. The first is a skin SST produced for both day and night (NSST) observations, derived from the long wave IR 11 and 12 micron wavelength channels, using a modified nonlinear SST algorithm intended to provide continuity of SST derived from heritage and current NASA sensors. At night, a second SST product is generated using the mid-infrared 3.95 and 4.05 micron wavelength channels which are unique to MODIS; the SST derived from these measurements is identified as SST4. The SST4 product has lower uncertainty, but due to sun glint can only be used at night. To generate the L3 products the L2 pixels are binned into an integerized sinusoidal area grid (ISEAG) and mapped into an equidistant cylindrical (also known as Platte Carre projection. Additional projection detailed can be found at https://oceancolor.gsfc.nasa.gov/docs/format/The NASA MODIS L3 SST data products are generated by the NASA Ocean Biology Processing Group (OBPG) and Peter Minnett and his team at the Rosenstiel School of Marine and Atmospheric Science (RSMAS) are responsible for sea surface temperature algorithm development, error statistics and quality flagging.

The CCMP datasets combine cross-calibrated satellite winds obtained from Remote Sensing Systems (REMSS) using a Variational Analysis Method (VAM) to produce a high-resolution (0.25 degree) gridded analysis. The CCMP data set includes cross-calibrated satellite winds derived from SSM/I, SSMIS, AMSR-E, TRMM TMI, QuikSCAT, SeaWinds, WindSat and other satellite instruments as they become available from REMSS. REMSS uses a cross-calibrated sea-surface emissivity model function which improves the consistency between wind speed retrievals from microwave radiometers (i.e., SSM/I, SSMIS, AMSR, TMI, and WindSat) and those from scatterometers (i.e., QuikSCAT and SeaWinds). The VAM combines these data with in situ measurements and a starting estimate (first guess) of the wind field. The European Center for Medium-Range Weather Forecasts (ECMWF) ERA-40 Reanalysis is used as the first-guess from 1987 to 1998. The ECMWF Operational analysis is used from January 1999 onward. All wind observations and analysis fields are referenced to a height of 10 meters. The ERA-40 can be obtained from the Computation and Information Systems Laboratory (CISL) at the National Center for Atmospheric Research (NCAR): http://rda.ucar.edu/datasets/ds117.0/. The ECMWF Operational analysis can also be obtained from CISL at NCAR: http://rda.ucar.edu/datasets/ds111.1/. Three products are distributed to complete the CCMP dataset series. L3.0 product contains high-resolution analyses every 6-hours. These data are then time averaged over monthly and 5-day periods to derive the L3.5 product. Directions from the L3.0 product are then assigned to the time and location of the passive microwave satellite wind speed observations to derive the L2.5 product. All datasets are distributed on a 0.25 degree cylindrical coordinate grid. This dataset is one in a series of First-Look (FLK) CCMP datasets and is a continuation and expansion of the SSM/I surface wind velocity project that began under the NASA Pathfinder Program. Refinements and upgrades to the FLK version will be incorporated under a new release (date to be determined) known as Late-look (LLK) and may include additional satellite datasets. All satellite surface wind data are obtained from REMSS under the DISCOVER project: Distributed Information Services: Climate/Ocean Products and Visualizations for Earth Research (http://www.discover-earth.org/index.html). The CCMP project is the result of an investigation funded by the NASA Making Earth Science data records for Use in Research Environments (MEaSUREs) program (http://community.eosdis.nasa.gov/measures/). In accordance with the MEaSUREs program, the CCMP datasets are also known as Earth System Data Records (ESDRs). In collaboration with private and government institutions, a team led by Dr. Robert Atlas (PI; proposal originally solicited by REASoN, and currently funded by MEaSURES) has created the CCMP project to provide multi-instrument ocean surface wind velocity ESDRs, with wide ranging research applications in meteorology and oceanography."@en ; "NONE"@en ; "EARTH SCIENCE"@en ; "2020-09-16"^^xsd:date ; "Dataset Policy created for CCMP_MEASURES_ATLAS_L4_OW_L3_0_WIND_VECTORS_FLK"@en ; "https://podaac.jpl.nasa.gov/" ; "English"@en ; "NASA/GSFC/NOAA"@en ; "PO.DAAC"@en ; "2009-05-10"^^xsd:date ; "PO.DAAC"@en ; "CCMP L3.0"@en ; "Cross-Calibrated Multi-Platform Ocean Surface Wind Vector L3.0 First-Look Analyses"@en ; "360.0"^^xsd:float ; "podaac@podaac.jpl.nasa.gov"@en ; "PODAAC-CCF30-01XXX" ; "Cross-Calibrated Multi-Platform Ocean Surface Wind Vector L3.0 First-Look Analyses"@en ; ""@en ; "Oceans"@en , "Geoscientific Information"@en ; "2017-04-28"^^xsd:date ; ""@en ; "0.25"^^xsd:float ; "Geographic Region"@en ; "Global"@en ; "WindSat"@en , "Earth Observing System, AQUA"@en , ""@en , "Making Earth Science Data Records for Use in Research Environments"@en , "Defense Meteorological Satellite Program-F11"@en , "Special Sensor Microwave Imager"@en , "Defense Meteorological Satellite Program-F08"@en , "Tropical Rainfall Measuring Mission"@en , "Defense Meteorological Satellite Program-F14"@en , "Special Sensor Microwave Imager/Sounder"@en , "Advanced Microwave Scanning Radiometer-EOS"@en , "Coriolis"@en , "Advanced Earth Observing Satellite-II"@en , "Defense Meteorological Satellite Program-F17"@en , "Defense Meteorological Satellite Program-F13"@en , "Defense Meteorological Satellite Program-F15"@en , "SeaWinds Scatterometer"@en , "Defense Meteorological Satellite Program-F10"@en , "QUIKSCAT"@en , "TRMM Microwave Imager"@en ; "0.25"^^xsd:float ; "CEOS IDN DIF"@en ; "9.8"^^xsd:float ; "78.0"^^xsd:float ; "https://podaac-tools.jpl.nasa.gov/drive/files/allData/ccmp/L3.0/docs/ccmp_users_guide.pdf" ; "NASA/GSFC/NOAA"@en ; "Data Center Contact"@en ; "TRMM"@en , "AMSR-E"@en , ""@en , "ADEOS-II"@en , "DMSP 5D-2/F10"@en , "DMSP 5D-2/F13"@en , "DMSP 5D-2/F8"@en , "DMSP 5D-2/F11"@en , "MEaSUREs"@en , "SSMIS"@en , "QUIKSCAT"@en , "USA/NASA"@en , "DMSP 5D-3/F17"@en , "Aqua"@en , "SSM/I"@en , "CORIOLIS"@en , "WINDSAT"@en , "SEAWINDS"@en , "TMI"@en , "DMSP 5D-3/F15"@en , "DMSP 5D-2/F14"@en ; "-78.0"^^xsd:float ; "1987-07-02"^^xsd:date ; "2011-12-31"^^xsd:date ; "6 Hour"@en ; "OCEAN WINDS"@en ; "OCEANS"@en ; "NONE"@en ; "SURFACE WINDS"@en ; "1.0"^^xsd:float ; "0.0"^^xsd:float . a base: ; owl:versionInfo "2020-09-16T19:36:14.520Z" , "2020-09-16T19:36:14.577Z" ; "A Group for High Resolution Sea Surface Temperature (GHRSST) global Level 4 sea surface temperature analysis produced daily on a 0.25 degree grid at the NOAA National Centers for Environmental Information.

It is a product of the European Organization for the Exploitation of Meteorological Satellites (EUMETSAT) Ocean and Sea Ice Satellite Application Facility (OSI SAF) provided through the Royal Netherlands Meteorological Institute (KNMI). This coastal dataset differs from the standard 25 km datasets in that it utilizes a spatial box filter (rather than the Hamming filter) to generate a spatial average of the Sigma-0 retrievals from the Level 1B dataset; all full resolution Sigma-0 retrievals within a 15 km radius of the wind vector cell centroid are used in the averaging. Since the full resolution L1B Sigma-0 retrievals are used, all non-sea retrievals are discarded prior to the Sigma-0 averaging. Each box average Sigma-0 is then used to compute the wind vector cell using the same CMOD7.n geophysical model function as in the standard OSI SAF ASCAT wind vector datasets. With this enhanced coastal retrieval, winds can be computed as close to ~15 km from the coast, as compared to the static ~35 km land mask in the standard 12.5 km dataset. Each file is provided in netCDF version 3 format, and contains one full orbit derived from 3-minute orbit granules. Latency is approximately 2 hours from the latest measurement. The beginning of the orbit is defined by the first wind vector cell measurement within the first 3-minute orbit granule that starts north of the Equator in the ascending node. ASCAT is a C-band dual fan beam radar scatterometer providing two independent swaths of backscatter retrievals in sun-synchronous polar orbit aboard the MetOp-A platform.

The project is comprised of two field campaigns and a series of cruises in regions of the Atlantic and Pacific Oceans exhibiting salinity extremes. SPURS employs a suite of state-of-the-art in-situ sampling technologies that, combined with remotely sensed salinity fields from the Aquarius/SAC-D, SMAP and SMOS satellites, provide a detailed characterization of salinity structure over a continuum of spatio-temporal scales. The SPURS-2 campaign involved two month-long cruises by the R/V Revelle in August 2016 and October 2017 combined with complementary sampling on a more continuous basis over this period by the schooner Lady Amber. Focused around a central mooring located near 10N,125W, the objective of SPURS-2 was to study the dynamics of the rainfall-dominated surface ocean at the western edge of the eastern Pacific fresh pool subject to high seasonal variability and strong zonal flows associated with the North Equatorial Current and Countercurrent. Two saildrones were deployed over a month period during the second SPURS-2 R/V Revelle cruise in 2017. Saildrone is a state-of-the-art, remotely guided, wind and solar powered unmanned surface vehicle (USV) capable of long distance deployments lasting up to 12 months. It is equipped with a suite of instruments and sensors providing high quality, georeferenced, near real-time, multi-parameter surface ocean and atmospheric observations while transiting at typical speeds of 3-5 knots. Saildrone data files are in netCDF format and CF/ACDD/NCEI compliant. They contain the saildrone platform telemetry and near-surface observational data (air temperature, sea surface skin and bulk temperatures, salinity, oxygen and chlorophyll-a concentrations, barometric pressure, wind speed and direction) for the entire cruise at 1 minute temporal resolution."@en ; "NONE"@en ; "EARTH SCIENCE"@en ; "2020-09-16"^^xsd:date ; "Dataset Creation via Metadata Tool"@en ; "https://podaac.jpl.nasa.gov/" ; "English"@en ; "D.

Terra was launched by NASA on December 18, 1999, into a sun synchronous, polar orbit with a daylight descending node at 10:30 am, to study the global dynamics of the Earth atmosphere, land and oceans. The MODIS captures data in 36 spectral bands at a variety of spatial resolutions. Two SST products can be present in these files. The first is a skin SST produced for both day and night observations, derived from the long wave IR 11 and 12 micron wavelength channels, using a modified nonlinear SST algorithm intended to provide continuity with SST derived from heritage and current NASA sensors. At night, a second SST product is produced using the mid-infrared 3.95 and 4.05 micron channels which are unique to MODIS; the SST derived from these measurements is identified as SST4. The SST4 product has lower uncertainty, but due to sun glint can only be produced at night. To generate the L3 products the L2 pixels are binned into an integerized sinusoidal area grid (ISEAG) and mapped into an equidistant cylindrical (also known as Platte Carre) projection. Additional projection detailed can be found at https://oceancolor.gsfc.nasa.gov/docs/format/The NASA MODIS L3 SST data products are generated by the NASA Ocean Biology Processing Group (OBPG) Peter Minnett and his team at the Rosenstiel School of Marine and Atmospheric Science (RSMAS) are responsible for sea surface temperature algorithm development, error statistics and quality flagging.

The CCMP datasets combine cross-calibrated satellite winds obtained from Remote Sensing Systems (REMSS) using a Variational Analysis Method (VAM) to produce a high-resolution (0.25 degree) gridded analysis. Wind directions from the resulting analysis are assigned to the location and time of the satellite-derived wind speed observations to create this value added dataset. The CCMP data set includes cross-calibrated satellite winds derived from SSM/I, SSMIS, AMSR-E, TRMM TMI, QuikSCAT, SeaWinds, WindSat and other satellites as they become available from REMSS. REMSS uses a cross-calibrated sea-surface emissivity model function which improves the consistency between wind speed retrievals from microwave radiometers (i.e., SSM/I, SSMIS, AMSR, TMI, WindSat) and those from scatterometers (i.e., QuikSCAT and SeaWinds). The VAM combines these data with in situ measurements and a starting estimate (first guess) of the wind field. The European Center for Medium-Range Weather Forecasts (ECMWF) ERA-40 Reanalysis is used as the first-guess from 1987 to 1998. The ECMWF Operational analysis is used from January 1999 onward. All wind observations and analysis fields are referenced to a height of 10 meters. The ERA-40 can be obtained from the Computation and Information Systems Laboratory (CISL) at the National Center for Atmospheric Research (NCAR): http://rda.ucar.edu/datasets/ds117.0/. The ECMWF Operational analysis can also be obtained from CISL at NCAR: http://rda.ucar.edu/datasets/ds111.1/. Three products are distributed to complete the CCMP dataset series. L3.0 product contains high-resolution analyses every 6-hours. These data are then time averaged over monthly and 5-day periods to derive the L3.5 product. Directions from the L3.0 product are then assigned to the time and location of the passive microwave satellite wind speed observations to derive the L2.5 product. All datasets are distributed on a 0.25 degree cylindrical coordinate grid. This dataset is one in a series of First-Look (FLK) CCMP datasets and is a continuation and expansion of the SSM/I surface wind velocity project that began under the NASA Pathfinder Program. Refinements and upgrades to the FLK version will be incorporated under a new release (date to be determined) known as Late-look (LLK) and may include additional satellite datasets. All satellite surface wind data are obtained from REMSS under the DISCOVER project: Distributed Information Services: Climate/Ocean Products and Visualizations for Earth Research (http://www.discover-earth.org/index.html). The CCMP project is the result of an investigation funded by the NASA Making Earth Science data records for Use in Research Environments (MEaSUREs) program (http://community.eosdis.nasa.gov/measures/). In accordance with the MEaSUREs program, the CCMP datasets are also known as Earth System Data Records (ESDRs). In collaboration with private and government institutions, a team led by Dr. Robert Atlas (PI; proposal originally solicited by REASoN, and currently funded by MEaSURES) has created the CCMP project to provide multi-instrument ocean surface wind velocity ESDRs, with wide ranging research applications in meteorology and oceanography."@en ; "NONE"@en ; "EARTH SCIENCE"@en ; "2020-09-16"^^xsd:date ; "Dataset Creation"@en ; "https://podaac.jpl.nasa.gov/" ; "English"@en ; "NASA/GSFC/NOAA"@en ; "PO.DAAC"@en ; "2009-05-08"^^xsd:date ; "PO.DAAC"@en ; "Cross-Calibrated Multi-Platform Ocean Surface Wind Vector L2.5 First-Look SSM/I-F15 Microwave Analyses"@en ; "Cross-Calibrated Multi-Platform Ocean Surface Wind Vector L2.5 First-Look SSM/I-F15 Microwave Analyses"@en ; "360.0"^^xsd:float ; "podaac@podaac.jpl.nasa.gov"@en ; "PODAAC-CCF25-01F15" ; "Cross-Calibrated Multi-Platform Ocean Surface Wind Vector L2.5 First-Look SSM/I-F15 Microwave Analyses"@en ; ""@en ; "Geoscientific Information"@en , "Oceans"@en ; "2011-01-21"^^xsd:date ; ""@en ; "0.25"^^xsd:float ; "Geographic Region"@en ; "Global"@en ; ""@en , "Defense Meteorological Satellite Program-F15"@en , "Special Sensor Microwave Imager"@en , "Making Earth Science Data Records for Use in Research Environments"@en ; "0.25"^^xsd:float ; "CEOS IDN DIF"@en ; "9.8"^^xsd:float ; "89.875"^^xsd:float ; "https://podaac-tools.jpl.nasa.gov/drive/files/allData/ccmp/L2.5/docs/ccmp_users_guide.pdf" ; "NASA/GSFC/NOAA"@en ; "Data Center Contact"@en ; ""@en , "USA/NASA"@en , "MEaSUREs"@en , "SSM/I"@en , "DMSP 5D-3/F15"@en ; "-89.875"^^xsd:float ; "1999-12-17"^^xsd:date ; "2006-08-14"^^xsd:date ; "12 Hour"@en ; "OCEAN WINDS"@en ; "OCEANS"@en ; "NONE"@en ; "SURFACE WINDS"@en ; "1.0"^^xsd:float ; "0.0"^^xsd:float . a base: ; owl:versionInfo "2020-09-16T19:36:14.471Z" ; "Aquarius Level 3 sea surface salinity (SSS) rain-flagged standard mapped image data contains gridded 1 degree spatial resolution SSS averagedover daily, 7 day, monthly, and seasonal time scales.

Terra was launched by NASA on December 18, 1999, into a sun synchronous, polar orbit with a daylight descending node at 10:30 am, to study the global dynamics of the Earth atmosphere, land and oceans. The MODIS captures data in 36 spectral bands at a variety of spatial resolutions. Two SST products can be present in these files. The first is a skin SST produced for both day and night observations, derived from the long wave IR 11 and 12 micron wavelength channels, using a modified nonlinear SST algorithm intended to provide continuity with SST derived from heritage and current NASA sensors. At night, a second SST product is produced using the mid-infrared 3.95 and 4.05 micron channels which are unique to MODIS; the SST derived from these measurements is identified as SST4. The SST4 product has lower uncertainty, but due to sun glint can only be produced at night. To generate the L3 products the L2 pixels are binned into an integerized sinusoidal area grid (ISEAG) and mapped into an equidistant cylindrical (also known as Platte Carre) projection.

SPURS employs a suite of state-of-the-art in-situ sampling technologies that, combined with remotely sensed salinity fields from the Aquarius/SAC-D, SMAP and SMOS satellites, provide a detailed characterization of salinity structure over a continuum of spatio-temporal scales. The SPURS-2 campaign involved two month-long cruises by the R/V Revelle in August 2016 and October 2017 combined with complementary sampling on a more continuous basis over this period by the schooner Lady Amber. Focused around a central mooring located near 10N,125W, the objective of SPURS-2 was to study the dynamics of the rainfall-dominated surface ocean at the western edge of the eastern Pacific fresh pool subject to high seasonal variability and strong zonal flows associated with the North Equatorial Current and Countercurrent. CTD (Conductivity, Temperature, Depth) casts were undertaken at stations on each of the two R/V Revelle cruises during SPURS-2. These shipboard lowered CTD probes provide continuous conductivity, salinity, and temperature vertical profile observations at fixed sampling locations. There were a total of 50 and 14 CTD casts made during the first and second R/V Revelle cruises respectively, and the data files available here are for continuous CTD profile data for each of the individual casts deployed.

The AVHRR is a space-borne scanning sensor on the National Oceanic and Atmospheric Administration (NOAA) family of Polar Orbiting Environmental Satellites (POES) having a operational legacy that traces back to the Television Infrared Observation Satellite-N (TIROS-N) launched in 1978. AVHRR instruments measure the radiance of the Earth in 5 (or 6) relatively wide spectral bands. The first two are centered around the red (0.6 micrometer) and near-infrared (0.9 micrometer) regions, the third one is located around 3.5 micrometer, and the last two sample the emitted thermal radiation, around 11 and 12 micrometers, respectively. The legacy 5 band instrument is known as AVHRR/2 while the more recent version, the AVHRR/3 (first carried on the NOAA-15 platform), acquires data in a 6th channel located at 1.6 micrometer. Typically the 11 and 12 micron channels are used to derive SST sometimes in combination with the 3.5 micron channel. The NOAA platforms are sun synchronous generally viewing the same earth location twice a day (latitude dependent) due to the relatively large AVHRR swath of approximately 2400 km. The highest ground resolution that can be obtained from the current AVHRR instruments is 1.1 km at nadir. AVHRR data are acquired in three formats: High Resolution Picture Transmission (HRPT), Local Area Coverage (LAC), and Global Area Coverage (GAC). HRPT data are full resolution image data transmitted to a ground stations as they are collected. LAC are also full resolution data, but the acquisition is prescheduled and recorded with an on-board tape recorder for subsequent transmission during a station overpass. GAC data provide daily subsampled global coverage recorded on tape recorders and then transmitted to a ground station. This particular dataset is derived from LAC data. Further binning and averaging of the 1.1 km LAC pixels results in a final dataset resolution of 2.2 km. The coverage of the LAC data can vary but generally contains scenes over the oceans adjacent to Australia and the North Indian Ocean."@en ; "None"@en ; "EARTH SCIENCE"@en ; "2020-09-16"^^xsd:date ; "2006-06-29 E.

Since the full resolution L1B Sigma-0 retrievals are used, all non-sea retrievals are discarded prior to the Sigma-0 averaging. Each box average Sigma-0 is then used to compute the vector cell wind using the same CMOD7 geophysical model function as in the operational OSI SAF ASCAT wind vector datasets. With this enhanced coastal retrieval, winds are computed as close to ~15 km from the coast. Each file corresponds to one complete orbit and is provided in netCDF version 3 format. The beginning of the orbit files is defined near the South Pole. ASCAT is a C-band fan beam radar scatterometer, providing two independent swaths of backscatter retrievals, aboard the MetOp-A platform in sun-synchronous polar orbit.

Aqua was launched by NASA on May 4, 2002, into a sun synchronous, polar orbit with a daylight ascending node at 13:30, formation flying in the A-train with other Earth Observation Satellites (EOS), to study the global dynamics of the Earth atmosphere, land and oceans. MODIS captures data in 36 spectral bands at a variety of spatial resolutions. Two SST products can be present in these files. The first is a skin SST produced for both day and night (NSST) observations, derived from the long wave IR 11 and 12 micron wavelength channels, using a modified nonlinear SST algorithm intended to provide continuity of SST derived from heritage and current NASA sensors. At night, a second SST product is generated using the mid-infrared 3.95 and 4.05 micron wavelength channels which are unique to MODIS; the SST derived from these measurements is identified as SST4. The SST4 product has lower uncertainty, but due to sun glint can only be used at night. To generate the L3 products the L2 pixels are binned into an integerized sinusoidal area grid (ISEAG) and mapped into an equidistant cylindrical (also known as Platte Carre projection.

The spatial coverage domain extends from latitude 30 degrees North to 50 degrees North and longitude 135 degrees West to 115 degrees West. The coastal wind vector retrieval algorithm developed by Barry Vanhoff and Michael Freilich has been utilized to provide improved coastal wind vector retrievals from QuikSCAT, resulting in retrievals as close as 5 km from coastlines. This dataset was developed by Barry Vanhoff, Craig Risien and Ted Strub and is made possible by funding provided by the NASA Research Opportunities in Space and Earth Science (ROSES) program and NOAA funded, Cooperative Institute for Oceanographic Satellite Studies (CIOSS) at the Oregon State University (OSU) College of Earth, Ocean and Atmospheric Sciences (CEOAS). PO.DAAC has agreed to provide this dataset as a special service to its users with the mutual understanding that issues or problems may remain in the data set, as noted below. All new users considering this dataset are strongly encouraged to first read the user guide and then to take full advantage of all potential dataset announcements through registration with PO.DAAC by emailing podaac@podaac.jpl.nasa.gov. It is further suggested that users examine a sequence of multiple parameter fields for the region and period of interest to ensure sufficient data quality and continuity. At present, it is worth noting the following known issues with regard to this dataset: a) data fields were produced using a modification of QuikSCAT Version 2 (i.e., previous version) winds, b) median-pass filter ambiguity removal is employed, hence not achieving the potential improvements from DIRTH, which affect the directional quality of the wind vector and stress data, c) does not incorporate the latest QuikSCAT re-processing improvements (i.e., Version 3 is most recent), d) different model winds (improved compared to Version 2 QuikSCAT L2B) are used in the ambiguity removal process for the entire dataset, and e) because of the lack of usable rain flags within 30 km of the coast, the rain flag value closest to the coast from the standard processing is applied between that rain flag location and the coast. There are some consequences in light of the above issues, notably: a) the wind vector fields should not be merged with any other existing QuikSCAT dataset, b) there is more inherent structure to the data (in both signal and noise) compared to Version 3 data, c) data fields are smoother in comparison to the Version 2 data, and d) potentially spurious wind vectors may arise within ~30 km of the coast due to unflagged rain contaminated data and/or residual land reflections.

The project is comprised of two field campaigns and a series of cruises in regions of the Atlantic and Pacific Oceans exhibiting salinity extremes. SPURS employs a suite of state-of-the-art in-situ sampling technologies that, combined with remotely sensed salinity fields from the Aquarius/SAC-D, SMAP and SMOS satellites, provide a detailed characterization of salinity structure over a continuum of spatio-temporal scales. The SPURS-2 campaign involved two month-long cruises by the R/V Revelle in August 2016 and October 2017 combined with complementary sampling on a more continuous basis over this period by the schooner Lady Amber. Focused around a central mooring located near 10N,125W, the objective of SPURS-2 was to study the dynamics of the rainfall-dominated surface ocean at the western edge of the eastern Pacific fresh pool subject to high seasonal variability and strong zonal flows associated with the North Equatorial Current and Countercurrent. Underway surface profiling systems (USPS) are automated measurement systems coupled to a research vessels water intake and GPS systems. They provide continuous, along-track surface temperature and salinity measurements at depths of 2, 3 and 5 m using through-hull ports in the bow of the ship.

The retrievals are provided on a non-uniform grid within the swath at 12.5 km pixel resolution. Higher resolution is achieved through a slice composite technique in which high resolution slice measurements from L1B data are composited into a 12.5 km wind vector cell. Version 3 processing begins with the same L1B (time-ordered backscatter) data as used in the previous processing. Version 3 has several improvements over the previous JPL processing of the QuikSCAT L2B winds: 1) changes to measurement binning, which was done in order to decrease noise and reduce gaps in the 12.5 km L2B wind retrievals, 2) an improved geophysical model function (GMF) to model the effect of wind on backscatter, 3) a neural network approach to correct rain contaminated winds speeds, 4) cross-track dependent wind speed biases were estimated and removed from the wind retrievals. The 12.5 km binning resolution enables users to obtain wind vector retrievals 10 km closer to shore when compared to the 25 km L2B dataset (only available in versions 1 and 2).

The CCMP datasets combine cross-calibrated satellite winds obtained from Remote Sensing Systems (REMSS) using a Variational Analysis Method (VAM) to produce a high-resolution (0.25 degree) gridded analysis. Wind directions from the resulting analysis are assigned to the location and time of the satellite-derived wind speed observations to create this value added dataset. The CCMP data set includes cross-calibrated satellite winds derived from SSM/I, SSMIS, AMSR-E, TRMM TMI, QuikSCAT, SeaWinds, WindSat and other satellite instruments as they become available from REMSS. REMSS uses a cross-calibrated sea-surface emissivity model function which improves the consistency between wind speed retrievals from microwave radiometers (i.e., SSM/I, SSMIS, AMSR, TMI, WindSat) and those from scatterometers (i.e., QuikSCAT and SeaWinds). The VAM combines these data with in situ measurements and a starting estimate (first guess) of the wind field. The European Center for Medium-Range Weather Forecasts (ECMWF) ERA-40 Reanalysis is used as the first-guess from 1987 to 1998. The ECMWF Operational analysis is used from January 1999 onward. All wind observations and analysis fields are referenced to a height of 10 meters. The ERA-40 can be obtained from the Computation and Information Systems Laboratory (CISL) at the National Center for Atmospheric Research (NCAR): http://rda.ucar.edu/datasets/ds117.0/. The ECMWF Operational analysis can also be obtained from CISL at NCAR: http://rda.ucar.edu/datasets/ds111.1/. Three products are distributed to complete the CCMP dataset series. L3.0 product contains high-resolution analyses every 6-hours. These data are then time averaged over monthly and 5-day periods to derive the L3.5 product. Directions from the L3.0 product are then assigned to the time and location of the passive microwave satellite wind speed observations to derive the L2.5 product. All datasets are distributed on a 0.25 degree cylindrical coordinate grid. This dataset is one in a series of First-Look (FLK) CCMP datasets and is a continuation and expansion of the SSM/I surface wind velocity project that began under the NASA Pathfinder Program. Refinements and upgrades to the FLK version will be incorporated under a new release (date to be determined) known as Late-look (LLK) and may include additional satellite datasets. All satellite surface wind data are obtained from REMSS under the DISCOVER project: Distributed Information Services: Climate/Ocean Products and Visualizations for Earth Research (http://www.discover-earth.org/index.html). The CCMP project is the result of an investigation funded by the NASA Making Earth Science data records for Use in Research Environments (MEaSUREs) program (http://community.eosdis.nasa.gov/measures/). In accordance with the MEaSUREs program, the CCMP datasets are also known as Earth System Data Records (ESDRs). In collaboration with private and government institutions, a team led by Dr. Robert Atlas (PI; proposal originally solicited by REASoN, and currently funded by MEaSURES) has created the CCMP project to provide multi-instrument ocean surface wind velocity ESDRs, with wide ranging research applications in meteorology and oceanography."@en ; "NONE"@en ; "EARTH SCIENCE"@en ; "2020-09-16"^^xsd:date ; "Dataset Creation"@en ; "https://podaac.jpl.nasa.gov/" ; "English"@en ; "NASA/GSFC/NOAA"@en ; "PO.DAAC"@en ; "2009-05-08"^^xsd:date ; "PO.DAAC"@en ; "Cross-Calibrated Multi-Platform Ocean Surface Wind Vector L2.5 First-Look SSM/I-F10 Microwave Analyses"@en ; "Cross-Calibrated Multi-Platform Ocean Surface Wind Vector L2.5 First-Look SSM/I-F10 Microwave Analyses"@en ; "360.0"^^xsd:float ; "podaac@podaac.jpl.nasa.gov"@en ; "PODAAC-CCF25-01F10" ; "Cross-Calibrated Multi-Platform Ocean Surface Wind Vector L2.5 First-Look SSM/I-F10 Microwave Analyses"@en ; ""@en ; "Oceans"@en , "Geoscientific Information"@en ; "2011-01-21"^^xsd:date ; ""@en ; "0.25"^^xsd:float ; "Geographic Region"@en ; "Global"@en ; "Special Sensor Microwave Imager"@en , ""@en , "Defense Meteorological Satellite Program-F10"@en , "Making Earth Science Data Records for Use in Research Environments"@en ; "0.25"^^xsd:float ; "CEOS IDN DIF"@en ; "9.8"^^xsd:float ; "89.875"^^xsd:float ; "https://podaac-tools.jpl.nasa.gov/drive/files/allData/ccmp/L2.5/docs/ccmp_users_guide.pdf" ; "NASA/GSFC/NOAA"@en ; "Data Center Contact"@en ; ""@en , "SSM/I"@en , "USA/NASA"@en , "MEaSUREs"@en , "DMSP 5D-2/F10"@en ; "-89.875"^^xsd:float ; "1990-12-08"^^xsd:date ; "1997-11-14"^^xsd:date ; "12 Hour"@en ; "OCEAN WINDS"@en ; "OCEANS"@en ; "NONE"@en ; "SURFACE WINDS"@en ; "1.0"^^xsd:float ; "0.0"^^xsd:float . a base: ; owl:versionInfo "2020-09-16T19:36:14.460Z" ; "Aquarius Level 3 sea surface salinity (SSS) rain-flagged standard mapped image data contains gridded 1 degree spatial resolution SSS averaged over daily, 7 day, monthly, and seasonaltime scales.

An additional RFI flag [3] is used to identify locations where the measured brightness temperature over land exceeds the expected limits of surface emissivity. This flag is not used to remove samples from further processing, but, in generating the radiometer RFI data, 100% RFI is assigned to points where this flag is raised. This product can be used to reproduce the RFI maps available on the Aquarius website at University of Maine (https://aquarius.umaine.edu/cgi/gal_radiometer.htm for the radiometer, and https://aquarius.umaine.edu/cgi/gal_scatterometer.htm for the scatterometer), by plotting the variables Rad_RFI_percent_AscDes_AllBeams and Scat_RFI_percent_AscDes_AllBeams on the latitude/longitude grid. Additionally, the user can generate maps by using only a particular beam or only ascending passes, for example. All combinations of beams and ascending/descending passes are possible.This product contains information about RFI, but it is also relevant for the retrieved Sea Surface Salinity (SSS). Over the ocean, the RFI percentage in this product corresponds to the amount of raw measurements discarded due to RFI contamination before SSS retrieval. Therefore, maps of the RFI percentage can give the user an indication of where RFI is more likely to have affected the quality of SSS retrievals, for a particular month, or for a series of months."@en ; "NONE"@en ; "EARTH SCIENCE"@en ; "2020-09-16"^^xsd:date ; "Dataset Creation via Metadata Tool"@en ; "https://podaac.jpl.nasa.gov/" ; "English"@en ; "Yan Soldo, Paolo De Matthaeis, David Levine"@en ; "NASA Goddard Space Flight Center (GSFC)"@en ; "2018-01-30"^^xsd:date ; "Goddard Space Flight Center, 8800 Greenbelt Rd.; Greeenbelt, Md., 20771"@en ; "Aquarius RFI Products"@en ; "Aquarius RFI Products"@en ; "180.0"^^xsd:float ; "podaac@podaac.jpl.nasa.gov"@en ; "PODAAC-AQR00-RFI01" ; "Aquarius Radio Frequency Interference (RFI) Ancillary Dataset V1.0"@en ; ""@en ; "Geoscientific Information"@en , "Oceans"@en ; "2017-12-19"^^xsd:date ; ""@en ; "1.0"^^xsd:float ; "Geographic Region"@en ; "Global"@en ; ""@en , "Aquarius Scatterometer"@en , "Aquarius SAC-D"@en , "Aquarius Radiometer"@en , "AQUARIUS SAC-D"@en ; "1.0"^^xsd:float ; "CEOS IDN DIF"@en ; "9.8"^^xsd:float ; "90.0"^^xsd:float ; "http://podaac.jpl.nasa.gov/salinity/data.html" ; "Aquarius Project NASA/CONAE"@en ; "Data Center Contact"@en ; "AQUARIUS_SCATTEROMETER"@en , "Aquarius_SAC-D"@en , ""@en , "AQUARIUS_RADIOMETER"@en , "AQUARIUS SAC-D"@en , "USA/NASA"@en ; "-90.0"^^xsd:float ; "2011-09-01"^^xsd:date ; "2015-06-01"^^xsd:date ; "1 Month"@en ; "SALINITY/DENSITY"@en ; "OCEANS"@en ; "NONE"@en ; "SALINITY"@en ; "1.0"^^xsd:float ; "-180.0"^^xsd:float . a base: ; owl:versionInfo "2020-09-16T19:36:14.487Z" ; "Aquarius Level 3 ancillary sea surface temperature (SST) standard mapped image data are the ancillary SST data used in the Aquarius calibration for salinity retrieval.

MODIS captures data in 36 spectral bands at a variety of spatial resolutions. Two SST products can be present in these files. The first is a skin SST produced for both day and night (NSST) observations, derived from the long wave IR 11 and 12 micron wavelength channels, using a modified nonlinear SST algorithm intended to provide continuity of SST derived from heritage and current NASA sensors. At night, a second SST product is generated using the mid-infrared 3.95 and 4.05 micron wavelength channels which are unique to MODIS; the SST derived from these measurements is identified as SST4. The SST4 product has lower uncertainty, but due to sun glint can only be used at night. To generate the L3 products the L2 pixels are binned into an integerized sinusoidal area grid (ISEAG) and mapped into an equidistant cylindrical (also known as Platte Carre projection.

The project is comprised of two field campaigns and a series of cruises in regions of the Atlantic and Pacific Oceans exhibiting salinity extremes. SPURS employs a suite of state-of-the-art in-situ sampling technologies that, combined with remotely sensed salinity fields from the Aquarius/SAC-D, SMAP and SMOS satellites, provide a detailed characterization of salinity structure over a continuum of spatio-temporal scales. The SPURS-2 campaign involved two month-long cruises by the R/V Revelle in August 2016 and October 2017 combined with complementary sampling on a more continuous basis over this period by the schooner Lady Amber. Focused around a central mooring located near 10N,125W, the objective of SPURS-2 was to study the dynamics of the rainfall-dominated surface ocean at the western edge of the eastern Pacific fresh pool subject to high seasonal variability and strong zonal flows associated with the North Equatorial Current and Countercurrent. A drifter is a passive Lagrangian sensor platform consisting of a surface buoy and tethered subsurface drogue. Drifter buoys contain GPS/ARGOS and satellite data transmitters, with sensors measuring temperature and other properties. For SPURS-2, a range of drifters were deployed during both Revelle SPURS-2 cruises. These included: standard Surface Velocity Program (SVP) drifters with salinity sensors added (SVP/S), Surface Contact Salinity drifters, CODE, SADOS, AOML and CARTHE-SUPRACT drifters.

The SST data in this data set are used operationally in oceanographic analyses and forecasts by the US Naval Oceanographic Office (NAVO). The MetOp satellite program is a European multi-satellite program to provide weather data services for monitoring climate and improving weather forecasts. MetOp-A, MetOp-B and Metop-C were respectively launched on 19 Oct 2006, 17 September 2012 and 7 November 2018. The program was jointly established by the European Space Agency (ESA) and the European Organization for the Exploitation of Meteorological Satellites (EUMETSAT) with the US National Oceanic and Atmospheric Administration (NOAA) contributing the AVHRR sensor. AVHRR instruments measure the radiance of the Earth in 5 (or 6) relatively wide spectral bands. The first two are centered around the red (0.6 micron) and near-infrared (0.9 micron) regions, the third one is located around 4 (3.6) micron, and the last two sample the emitted thermal radiation, around 11 and 12 micron, respectively. The legacy 5 band instrument is known as AVHRR/2 while the more recent version, the AVHRR/3 (first carried on the NOAA-15 platform), acquires data in a 6th channel located at 1.6 micron. Typically, the 11 and 12 micron channels are used to derive SST sometimes in combination with the 3.5 micron channel. The swath of the AVHRR sensor is a relatively large 2400 km. All MetOp platforms are sun synchronous and generally view the same earth location twice a day (latitude dependent). The ground native resolution of the AVHRR instruments is approximately 1.1 km at nadir and degrades off nadir. This particular data set is produced from legacy Global Area Coverage (GAC) data that are derived from a sample averaging of the full resolution global AVHRR data. Four out of every five samples along the scan line are used to compute on average value and the data from only every third scan line are processed, yielding an effective 4 km spatial resolution at nadir. The v2.0 is the updated version from current v1.0 with extensive algorithm improvements and upgrades. The major improvements include: 1) Significant changes in contaminant/cloud detection; 2) Increased the spatial resolution from 9 km to 4 km; 3) Updated compliance with GDS2, ACDD 1.3, and CF 1.6; and 4) Removed the dependency on the High-resolution Infrared Radiation Sounder (HIRS) sensor (only available to MetOp-A/B), thus allowing for the consistent inter-calibration and the processing of MetOp-A/B/C data"@en ; "None"@en ; "EARTH SCIENCE"@en ; "2020-09-16"^^xsd:date ; "Dataset Creation via Metadata Tool"@en ; "https://podaac.jpl.nasa.gov/" ; "English"@en ; "Naval Oceanographic Office"@en ; "Naval Oceanographic Office"@en ; "2020-07-24"^^xsd:date ; "Stennis Space Center, MS, USA"@en ; "METOP-C AVHRR GAC MCSST"@en ; "METOP-C AVHRR GAC L2P swath SST data set"@en ; "180.0"^^xsd:float ; "podaac@podaac.jpl.nasa.gov"@en ; "PODAAC-GHMTC-2PN20" ; "GHRSST Level 2P Global Sea Surface Temperature v2.0 from the AVHRR on the MetOp-C satellite produced by NAVO"@en ; ""@en ; "Oceans"@en , "Geoscientific Information"@en ; "2020-05-26"^^xsd:date ; ""@en ; "0.04"^^xsd:float ; "Geographic Region"@en ; "Global"@en ; "Advanced Very High Resolution Radiometer-3"@en , "Group for High Resolution Sea Surface Temperature"@en , ""@en , "Meteorological Operational Satellite - C"@en ; "0.04"^^xsd:float ; "CEOS IDN DIF"@en ; "9.8"^^xsd:float ; "80.0"^^xsd:float ; "https://podaac-tools.jpl.nasa.gov/drive/files/allData/ghrsst/docs/GDS20r5.pdf" ; "DOD/USNAVY/NAVOCEANO"@en ; "Data Center Contact"@en ; "AVHRR-3"@en , "USA/NASA"@en , ""@en , "GHRSST"@en , "METOP-C"@en ; "-70.0"^^xsd:float ; "2020-06-10"^^xsd:date ; "OCEAN TEMPERATURE"@en ; "OCEANS"@en ; "None"@en ; "SEA SURFACE TEMPERATURE"@en ; "2.0"^^xsd:float ; "-180.0"^^xsd:float . a base: ; owl:versionInfo "2020-09-16T19:36:14.283Z" ; "This dataset contains the ISS-RapidScat on Level 2A 25km science data record, which provides surface-flagged sigma-0 in 25km Wind Vector Cells processed using the pulse \"egg\" Sigma-0 data provided by the Level 1B dataset.

To minimize the L2A data volume, the Sigma-0 cell data are stored as \"lists\" for each WVC row, with each list indexed by a \"cell_index\" array to indicate the cross-track WVC membership of the data. Each cell is then checked for land or ice and flagged accordingly. Attenuation corrections for each Sigma-0 measurement are also provided. Data are provided in single-orbit files in HDF-4 format.

The NASA mission is officially referred to as ISS-RapidScat. Unlike QuikSCAT, ISS-RapidScat is not in sun-synchronous orbit, and flies at roughly half the altitude with a low inclination angle that restricts data coverage to the tropics and mid-latitude regions; the extent of latitudinal coverage stretches from approximately 61 degrees North to 61 degrees South.

The project involves two field campaigns and a series of cruises in regions of the Atlantic and Pacific Oceans exhibiting salinity extremes. SPURS employs a suite of state-of-the-art in-situ sampling technologies that, combined with remotely sensed salinity fields from the Aquarius/SAC-D and SMOS satellites, provide a detailed characterization of salinity structure over a continuum of spatio-temporal scales. The SPURS-1 campaign involved a series of 5 cruises during 2012 - 2013 seeking to characterize the salinity structure and balance in a high salinity, high evaporation, and low rainfall region of the subtropical North Atlantic. It aims to resolve processes responsible for maintaining the subtropical surface salinity maximum in this region and within a 900 x 800-mile square study area centered at 25N, 38W. An Underway-CTD (UCTD) was deployed on 2 of the SPURS-1 cruises. An UCTD is a towed CTD instrument providing conductivity, salinity and temperature depth profile observations while underway at up to 20kts. 771 UCTD casts occurred during the Knorr and Endeavor-I cruises (6 Sept-9 Oct 2012 and 15 Mar-15 Apr 2013 respectively) utilizing an Oceanscience instrument.

Average daily, weekly (8 day), monthly and annual skin SST products at are available at both 4.63 and 9.26 km spatial resolution. Aqua was launched by NASA on May 4, 2002, into a sun synchronous, polar orbit with a daylight ascending node at 13:30, formation flying in the A-train with other Earth Observation Satellites (EOS), to study the global dynamics of the Earth atmosphere, land and oceans. MODIS captures data in 36 spectral bands at a variety of spatial resolutions. Two SST products can be present in these files. The first is a skin SST produced for both day and night (NSST) observations, derived from the long wave IR 11 and 12 micron wavelength channels, using a modified nonlinear SST algorithm intended to provide continuity of SST derived from heritage and current NASA sensors. At night, a second SST product is generated using the mid-infrared 3.95 and 4.05 micron wavelength channels which are unique to MODIS; the SST derived from these measurements is identified as SST4. The SST4 product has lower uncertainty, but due to sun glint can only be used at night. To generate the L3 products the L2 pixels are binned into an integerized sinusoidal area grid (ISEAG) and mapped into an equidistant cylindrical (also known as Platte Carre projection. Additional projection detailed can be found at https://oceancolor.gsfc.nasa.gov/docs/format/The NASA MODIS L3 SST data products are generated by the NASA Ocean Biology Processing Group (OBPG) and Peter Minnett and his team at the Rosenstiel School of Marine and Atmospheric Science (RSMAS) are responsible for sea surface temperature algorithm development, error statistics and quality flagging.

The Level 2B wind vectors are binned on a 12.5 km Wind Vector Cell (WVC) grid and processed using the Level 2A Sigma-0 dataset. RapidScat is a Ku-band dual beam circular rotating scatterometer retaining much of the same hardware and functionality of QuikSCAT, with exception of the antenna sub-system and digital interface to the International Space Station (ISS) Columbus module, which is where RapidScat is mounted. The NASA mission is officially referred to as ISS-RapidScat. Unlike QuikSCAT, ISS-RapidScat is not in sun-synchronous orbit, and flies at roughly half the altitude with a low inclination angle that restricts data coverage to the tropics and mid-latitude regions; the extent of latitudinal coverage stretches from approximately 61 degrees North to 61 degrees South. Furthermore, there is no consistent local time of day retrieval. This dataset is provided in a netCDF-3 file format that follows the netCDF-4 classic model (i.e., generated by the netCDF-4 API) and made available via FTP and OPeNDAP. For data access, please click on the \"Data Access\" tab above. This Version 1.1 dataset differs from the previous Version 1 dataset as follows: 1) A new neural network approach for high wind speeds provided rain corrections for the \"retrieve_wind_speed\" variable for wind speeds in excess of 15 m/s. 2) The data variables containing the number of measurements of each type for each wind vector cell have been corrected; these variables include \"number_in_aft\", \"number_in_fore\", \"number_out_aft\", and \"number_out_fore\". 3) The \"wind_obj\" data variable has been corrected to include the proper data for the conditional probability for the objective DIRTH function values. It is advised for users to avoid using the \"wind_obj\" variable in this dataset since it is minimally applicable and meant primarily for quality assurance; for users who wish to access the objective function values for each ambiguity, it is suggested to use only the \"ambiguity_obj\" variable. The \"wind_obj\" variable contains DIRTH probabilities (which are derived form the \"ambiguity_obj\" objective function values) in the range of 0 to 1 indicating the conditional probability that the true direction is within + or - 2.5 degrees of the retrieved wind direction given the observed backscatter measurements in the cell.

The Suomi National Polar-orbiting Partnership (S-NPP) is a collaboration between NASA and NOAA. NOAA is responsible for all JPSS products, including SST from the Visible Infrared Imaging Radiometer Suite (VIIRS). VIIRS is a whiskbroom scanning radiometer, which takes measurements in the cross-track direction within a field of view of 112.56-deg using 16 detectors and a double-sided mirror assembly. At a nominal altitude of 829 km, the swath width is 3,060 km, providing global daily coverage for both day and night passes. VIIRS has 22 spectral bands covering the spectrum from 0.4-12 um, including 16 moderate resolution bands (M-bands). The L2P SST product is derived at the native sensor resolution (~0.75 km at nadir, ~1.5 km at swath edge) using NOAA's Advanced Clear-Sky Processor for Ocean (ACSPO) system, and reported in 10-minute granules in netCDF4 format, compliant with the GHRSST Data Specification version 2 (GDS2). There are 144 granules per 24hr interval, with a total data volume of 27GB/day. In addition to pixel-level earth locations, Sun-sensor geometry, and ancillary data from the NCEP global weather forecast, ACSPO outputs include four brightness temperatures (BTs) in M12 (3.7um), M14 (8.6um), M15 (11um), and M16 (12um) bands, and two reflectances in M5 (0.67um) and M7 (0.87um) bands. The reflectances are used for cloud identification. Beginning with ACSPO v2.60, all BTs and reflectances are destriped (Bouali and Ignatov, 2014) and resampled (Gladkova et al., 2016), to minimize the effect of bow-tie distortions and deletions. SSTs are retrieved from destriped BTs.SSTs are derived from BTs using the Multi-Channel SST (MCSST; night) and Non-Linear SST (NLSST; day) algorithms (Petrenko et al., 2014). An ACSPO clear-sky mask (ACSM) is provided in each pixel as part of variable l2p_flags, which also includes day/night, land, ice, twilight, and glint flags (Petrenko et al., 2010). Fill values are reported in all invalid pixels, including those with >5 km inland. For each valid water pixel (defined as ocean, sea, lake or river, and up to 5 km inland), four BTs in M12/14/15/16 (included for those users interested in direct \"radiance assimilation\", e.g., NOAA NCEP, NASA GMAO, ECMWF) and two refelctances in M5/7 are reported, along with derived SST. Other variables include NCEP wind speed and ACSPO SST minus reference SST (Canadian Met Centre 0.1deg L4 SST; available at https://podaac.jpl.nasa.gov/dataset/CMC0.1deg-CMC-L4-GLOB-v3.0). Only ACSM confidently clear pixels are recommended (equivalent to GDS2 quality level=5). Per GDS2 specifications, two additional Sensor-Specific Error Statistics layers (SSES bias and standard deviation) are reported in each pixel with QL=5. Note that users of ACSPO data have the flexibility to ignore the ACSM and derive their own clear-sky mask, and apply it to BTs and SSTs. They may also ignore ACSPO SSTs, and derive their own SSTs from the original BTs.The ACSPO VIIRS L2P product is monitored and validated against quality controlled in situ data provided by NOAA in situ SST Quality Monitor system (iQuam; Xu and Ignatov, 2014) using another NOAA system, SST Quality Monitor (SQUAM; Dash et al, 2010). Corresponding clear-sky BTs are validated against RTM simulations in the Monitoring IR Clear-sky Radiances over Ocean for SST system (MICROS; Liang and Ignatov, 2011).

DDMs are normally sampled over a restricted range of delay and Doppler values centered on the values at the specular point of reflection.

Full DDMs are sampled over a wider range of delay and Doppler values and retain their full (lossless) bit resolution.

Average daily, weekly (8 day), monthly and annual skin SST products are available at both 4.63 and 9.26 km spatial resolution. Terra was launched by NASA on December 18, 1999, into a sun synchronous, polar orbit with a daylight descending node at 10:30 am, to study the global dynamics of the Earth atmosphere, land and oceans. The MODIS captures data in 36 spectral bands at a variety of spatial resolutions. Two SST products can be present in these files. The first is a skin SST produced for both day and night observations, derived from the long wave IR 11 and 12 micron wavelength channels, using a modified nonlinear SST algorithm intended to provide continuity with SST derived from heritage and current NASA sensors. At night, a second SST product is produced using the mid-infrared 3.95 and 4.05 micron channels which are unique to MODIS; the SST derived from these measurements is identified as SST4. The SST4 product has lower uncertainty, but due to sun glint can only be produced at night. To generate the L3 products the L2 pixels are binned into an integerized sinusoidal area grid (ISEAG) and mapped into an equidistant cylindrical (also known as Platte Carre) projection. Additional projection detailed can be found at https://oceancolor.gsfc.nasa.gov/docs/format/The NASA MODIS L3 SST data products are generated by the NASA Ocean Biology Processing Group (OBPG) Peter Minnett and his team at the Rosenstiel School of Marine and Atmospheric Science (RSMAS) are responsible for sea surface temperature algorithm development, error statistics and quality flagging.

The MetOp satellite program is a European undertaking providing weather data services for monitoring climate and improving weather forecasts. It was jointly established by the European Space Agency (ESA) and the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) with a contribution by the US National Oceanic and Atmospheric Administration (NOAA) of an AVHRR sensor identical to those flying on the family of Polar Orbiting Environmental Satellites (POES). AVHRR instruments measure the radiance of the Earth in 5 (or 6) relatively wide spectral bands. The first two are centered around the red (0.6 micrometer) and near-infrared (0.9 micrometer) regions, the third one is located around 3.5 micrometer, and the last two sample the emitted thermal radiation, around 11 and 12 micrometers, respectively. The legacy 5 band instrument is known as AVHRR/2 while the more recent version, the AVHRR/3 (first carried on the NOAA-15 platform), acquires data in a 6th channel located at 1.6 micrometer. Typically the 11 and 12 micron channels are used to derive SST sometimes in combination with the 3.5 micron channel. The MetOp-A platform is sun synchronous generally viewing the same earth location twice a day (latitude dependent) due to the relatively large AVHRR swath of approximately 2400 km. The highest ground resolution that can be obtained from the current AVHRR instruments is 1.1 km at nadir. This particular dataset is produced from Global Area Coverage (GAC) data that are derived from an on-board sample averaging of the full resolution global AVHRR data. Four out of every five samples along the scan line are used to compute on average value and the data from only every third scan line are processed, yielding an effective 4 km resolution at nadir. Further binning and averaging of these pixels results in a final dataset resolution of 8.8 km."@en ; "None"@en ; "EARTH SCIENCE"@en ; "2020-09-16"^^xsd:date ; "Dataset Creation via Metadata Tool"@en ; "https://podaac.jpl.nasa.gov/" ; "English"@en ; "Naval Oceanographic Office"@en ; "Naval Oceanographic Office"@en ; "2014-10-27"^^xsd:date ; "Stennis Space Center, MS, USA"@en ; "GHRSST Level 2P Global Bulk Sea Surface Temperature from the Advanced Very High Resolution Radiometer (AVHRR) on the MetOp-A satellite produced by NAVO"@en ; "METOP-A AVHRR GAC L2P swath SST data set"@en ; "180.0"^^xsd:float ; "podaac@podaac.jpl.nasa.gov"@en ; "PODAAC-GHMTG-2PN02" ; "GHRSST Level 2P Global 1m Sea Surface Temperature from the Advanced Very High Resolution Radiometer (AVHRR) on the MetOp-A satellite produced by NAVO"@en ; ""@en ; "Geoscientific Information"@en , "Oceans"@en ; "2017-04-28"^^xsd:date ; ""@en ; "Geographic Region"@en ; "Global"@en ; "Advanced Very High Resolution Radiometer-3"@en , "Meteorological Operational Satellite - A"@en , ""@en , "Group for High Resolution Sea Surface Temperature"@en ; "CEOS IDN DIF"@en ; "9.8"^^xsd:float ; "80.0"^^xsd:float ; "" ; "Naval Oceanographic Office"@en ; "Data Center Contact"@en ; "GHRSST"@en , "AVHRR-3"@en , "USA/NASA"@en , ""@en , "METOP-A"@en ; "-70.0"^^xsd:float ; "2013-09-24"^^xsd:date ; "2020-07-07"^^xsd:date ; "OCEAN TEMPERATURE"@en ; "OCEANS"@en ; "None"@en ; "SEA SURFACE TEMPERATURE"@en ; "1.0"^^xsd:float ; "-180.0"^^xsd:float . a base: ; owl:versionInfo "2020-09-16T19:36:14.448Z" ; "Aquarius Level 3 ocean surface wind speed standard mapped image data contains gridded 1 degree spatial resolution wind speed data averaged over daily, 7 day, monthly, and seasonal time scales.

Enhancements with this release include: use of an improved 0.125 degree land correction table with land emission based on SMAP TB; replacement of the previous NCEP sea-ice mask with one based on RSS AMSR-2 and implementing a sea-ice threshold of 0.3% (gain weighted sea-ice fraction); revised solar flagging that depends on glint angle and wind speed; inclusion of estimated SSS-uncertainty; consolidation of both 40KM and 70KM SMAP-SSS datasets as variable fields in a single data product. Daily data files for this product are based on SSS averages spanning an 8-day moving time window. SMAP data begins on April 1,2015 and is ongoing. L3 products are global in extent and gridded at 0.25degree x 0.25degree with a default spatial feature resolution of approximately 70KM. Note that while a SSS 40KM variable is also included in the product, for most open ocean applications, the default SSS variable (70KM) is best used as they are significantly less noisy than the 40KM data.

This is a PI led dataset produced at the International Pacific Research Center (IPRC) at the University of Hawaii (Manoa) School of Ocean and Earth Science and Technology. The optimal interpolation (OI) mapping procedure used to create this product corrects for systematic spatial biases in Aquarius SSS data with respect to near-surface in situ salinity observations and takes into account available statistical information about the signal and noise, specific to the Aquarius instrument. Bias fields are constructed by differencing in situ from Aquarius derived SSS fields obtained separately using ascending and descending satellite observations for each of the three Aquarius beams, and by removal of small-scale noise and low-pass filtering along-track using a two-dimensional Hanning window procedures prior to application of the OI algorithm. Additional enhancements for this new version of the product include: 1) The V5.0 (end-of mission) version of Aquarius Level-2 (swath) SSS data are used as input data for the OI SSS analysis. 2) The source of the first guess fields has changed from the APDRC Argo-derived SSS product to the average of four different in-situ based SSS products. 3) The bias correction algorithm has changed to adjust SSS retrievals for large-scale systematic biases on a repeat-track basis. 4) New, less restrictive thresholds are implemented to filter observations for land and ice contamination, thus improving coverage in the coastal areas and semi-enclosed seas. 5) Level-2 RFI masks for descending and ascending satellite passes are used to discard observations in specific geographic zones where excessive ascending-descending differences are observed due to contamination from undetected RFI.

The project is comprised of two field campaigns and a series of cruises in regions of the Atlantic and Pacific Oceans exhibiting salinity extremes. SPURS employs a suite of state-of-the-art in-situ sampling technologies that, combined with remotely sensed salinity fields from the Aquarius/SAC-D, SMAP and SMOS satellites, provide a detailed characterization of salinity structure over a continuum of spatio-temporal scales. The SPURS-2 campaign involved two month-long cruises by the R/V Revelle in August 2016 and October 2017 combined with complementary sampling on a more continuous basis over this period by the schooner Lady Amber. Focused around a central mooring located near 10N,125W, the objective of SPURS-2 was to study the dynamics of the rainfall-dominated surface ocean at the western edge of the eastern Pacific fresh pool subject to high seasonal variability and strong zonal flows associated with the North Equatorial Current and Countercurrent. The Salinity Snake (SS) measures sea surface salinity in the top 1 - 2 cm of the water column, which is the radiometric depth of L-Band satellite radiometers such as on Aquarius/SAC-D, SMAP and SMOS satellites that measure salinity remotely. The SS consists of four key components: a 10m boom mast, a hose, which is deployed from this boom, a powerful self-priming peristaltic pump which transports a constant stream of a seawater/air emulsion, and a shipboard apparatus, which filters, de-bubbles, sterilizes and analyses the salinity of the water.

This dataset contains estimates of geopotential field derived from the Gravity Recovery and Climate Experiment (GRACE) mission measurements and a non-tidal oceanic model produced by the German Research Centre for Geosciences (GFZ). The data are in spherical harmonics averaged over approximately a month. The primary objective of the GRACE mission is to obtain accurate estimates of the mean and time-variable components of the gravity field variations. This objective is achieved by making continuous measurements of the change in distance between twin spacecraft, co-orbiting in about 500 km altitude, near circular, polar orbit, spaced approximately 200 km apart, using a microwave ranging system. In addition to these range change, the non-gravitional forces are measured on each satellite using a high accuracy electrostatic, room-temperature accelerometer. The satellite orientation and position (and timing) are precisely measured using twin star cameras and a GPS receiver, respectively. Spatial and temporal variations in the gravity field affect the orbits (or trajectories) of the twin spacecraft differently. These differences are manifested as changes in the distance between the spacecraft, as they orbit the Earth. This change in distance is reflected in the time-of-flight of microwave signals transmitted and received nearly simultaneously between the two spacecraft. The change in this time of fight is continuously measured by tracking the phase of the microwave carrier signals. The so called dual-one-way range change measurements can be reconstructed from these phase measurements. This range change (or its numerically derived derivatives), along with other mission and ancillary data, is subsequently analyzed to extract the parameters of an Earth gravity field model."@en ; "none"@en ; "EARTH SCIENCE"@en ; "2020-09-16"^^xsd:date ; "Dataset Creation via Metadata Tool"@en ; "https://podaac.jpl.nasa.gov/" ; "English"@en ; "GRACE"@en ; "GFZ"@en ; "2018-08-31"^^xsd:date ; "JPL PO.DAAC"@en ; "GRACE NON-TIDAL OCEAN GEOPOTENTIAL COEFFICIENTS GFZ (GAB)"@en ; "GRACE_GAB_L2_GRAV_GFZ_RL06"@en ; "180.0"^^xsd:float ; "podaac@podaac.jpl.nasa.gov"@en ; "PODAAC-GRGAB-20G06" ; "GRACE NON-TIDAL OCEAN GEOPOTENTIAL COEFFICIENTS GFZ RELEASE 6.0 GAB"@en ; ""@en ; "Oceans"@en , "Geoscientific Information"@en ; "2018-08-06"^^xsd:date ; ""@en ; "Geographic Region"@en ; "Global"@en ; "GRACE K-Band Ranging System"@en , "Gravity Recovery and Climate Experiment"@en , "GRACE SuperSTAR Accelerometer"@en , ""@en , "Star Camera Assembly"@en ; "CEOS IDN DIF"@en ; "9.8"^^xsd:float ; "88.0"^^xsd:float ; "https://podaac-tools.jpl.nasa.gov/drive/files/allData/grace/docs/" ; "GRACE/GFZ"@en ; "Data Center Contact"@en ; "GRACE ACC"@en , "GRACE"@en , "USA/NASA"@en , ""@en , "GRACE KBR"@en , "GRACE SCA"@en ; "-88.0"^^xsd:float ; "2002-04-05"^^xsd:date ; "2017-07-01"^^xsd:date ; "GRAVITY/GRAVITATIONAL FIELD"@en , "OCEAN PRESSURE"@en ; "SOLID EARTH"@en , "OCEANS"@en ; "none"@en ; "GRAVITY"@en , "WATER PRESSURE"@en ; "6.0"^^xsd:float ; "-180.0"^^xsd:float . a base: ; owl:versionInfo "2020-09-16T19:36:14.598Z" , "2020-09-16T19:36:14.556Z" ; "Day and night spatially gridded (L3) global NASA skin sea surface temperature (SST) products from the Moderate-resolution Imaging Spectroradiometer (MODIS) onboard the Terra satellite. Average daily, weekly (8 day), monthly and annual skin SST products are available at both 4.63 and 9.26 km spatial resolution. Terra was launched by NASA on December 18, 1999, into a sun synchronous, polar orbit with a daylight descending node at 10:30 am, to study the global dynamics of the Earth atmosphere, land and oceans. The MODIS captures data in 36 spectral bands at a variety of spatial resolutions. Two SST products can be present in these files. The first is a skin SST produced for both day and night observations, derived from the long wave IR 11 and 12 micron wavelength channels, using a modified nonlinear SST algorithm intended to provide continuity with SST derived from heritage and current NASA sensors. At night, a second SST product is produced using the mid-infrared 3.95 and 4.05 micron channels which are unique to MODIS; the SST derived from these measurements is identified as SST4. The SST4 product has lower uncertainty, but due to sun glint can only be produced at night. To generate the L3 products the L2 pixels are binned into an integerized sinusoidal area grid (ISEAG) and mapped into an equidistant cylindrical (also known as Platte Carre) projection. Additional projection detailed can be found at https://oceancolor.gsfc.nasa.gov/docs/format/The NASA MODIS L3 SST data products are generated by the NASA Ocean Biology Processing Group (OBPG) Peter Minnett and his team at the Rosenstiel School of Marine and Atmospheric Science (RSMAS) are responsible for sea surface temperature algorithm development, error statistics and quality flagging.

The CCMP datasets combine cross-calibrated satellite winds obtained from Remote Sensing Systems (REMSS) using a Variational Analysis Method (VAM) to produce a high-resolution (0.25 degree) gridded analysis. Wind directions from the resulting analysis are assigned to the location and time of the satellite-derived wind speed observations to create this value added dataset. The CCMP data set includes cross-calibrated satellite winds derived from SSM/I, SSMIS, AMSR-E, TRMM TMI, QuikSCAT, SeaWinds, WindSat and other satellite instruments as they become available from REMSS. REMSS uses a cross-calibrated sea-surface emissivity model function which improves the consistency between wind speed retrievals from microwave radiometers (i.e., SSM/I, SSMIS, AMSR, TMI, WindSat) and those from scatterometers (i.e., QuikSCAT and SeaWinds). The VAM combines these data with in situ measurements and a starting estimate (first guess) of the wind field. The European Center for Medium-Range Weather Forecasts (ECMWF) ERA-40 Reanalysis is used as the first-guess from 1987 to 1998. The ECMWF Operational analysis is used from January 1999 onward. All wind observations and analysis fields are referenced to a height of 10 meters. The ERA-40 can be obtained from the Computation and Information Systems Laboratory (CISL) at the National Center for Atmospheric Research (NCAR): http://rda.ucar.edu/datasets/ds117.0/. The ECMWF Operational analysis can also be obtained from CISL at NCAR: http://rda.ucar.edu/datasets/ds111.1/. Three products are distributed to complete the CCMP dataset series. L3.0 product contains high-resolution analyses every 6-hours. These data are then time averaged over monthly and 5-day periods to derive the L3.5 product. Directions from the L3.0 product are then assigned to the time and location of the passive microwave satellite wind speed observations to derive the L2.5 product. All datasets are distributed on a 0.25 degree cylindrical coordinate grid. This dataset is one in a series of First-Look (FLK) CCMP datasets and is a continuation and expansion of the SSM/I surface wind velocity project that began under the NASA Pathfinder Program. Refinements and upgrades to the FLK version will be incorporated under a new release (date to be determined) known as Late-look (LLK) and may include additional satellite datasets. All satellite surface wind data are obtained from REMSS under the DISCOVER project: Distributed Information Services: Climate/Ocean Products and Visualizations for Earth Research (http://www.discover-earth.org/index.html). The CCMP project is the result of an investigation funded by the NASA Making Earth Science data records for Use in Research Environments (MEaSUREs) program (http://community.eosdis.nasa.gov/measures/). In accordance with the MEaSUREs program, the CCMP datasets are also known as Earth System Data Records (ESDRs). In collaboration with private and government institutions, a team led by Dr. Robert Atlas (PI; proposal originally solicited by REASoN, and currently funded by MEaSURES) has created the CCMP project to provide multi-instrument ocean surface wind velocity ESDRs, with wide ranging research applications in meteorology and oceanography."@en ; "NONE"@en ; "EARTH SCIENCE"@en ; "2020-09-16"^^xsd:date ; "Dataset Creation"@en ; "https://podaac.jpl.nasa.gov/" ; "English"@en ; "NASA/GSFC/NOAA"@en ; "PO.DAAC"@en ; "2009-05-08"^^xsd:date ; "PO.DAAC"@en ; "Cross-Calibrated Multi-Platform Ocean Surface Wind Vector L2.5 First-Look AMSR-E Microwave Analyses"@en ; "Cross-Calibrated Multi-Platform Ocean Surface Wind Vector L2.5 First-Look AMSR-E Microwave Analyses"@en ; "360.0"^^xsd:float ; "podaac@podaac.jpl.nasa.gov"@en ; "PODAAC-CCF25-01AMS" ; "Cross-Calibrated Multi-Platform Ocean Surface Wind Vector L2.5 First-Look AMSR-E Microwave Analyses"@en ; ""@en ; "Geoscientific Information"@en , "Oceans"@en ; "2011-01-21"^^xsd:date ; ""@en ; "0.25"^^xsd:float ; "Geographic Region"@en ; "Global"@en ; "Making Earth Science Data Records for Use in Research Environments"@en , ""@en , "Advanced Microwave Scanning Radiometer-EOS"@en , "Earth Observing System, AQUA"@en ; "0.25"^^xsd:float ; "CEOS IDN DIF"@en ; "9.8"^^xsd:float ; "89.875"^^xsd:float ; "https://podaac-tools.jpl.nasa.gov/drive/files/allData/ccmp/L2.5/docs/ccmp_users_guide.pdf" ; "NASA/GSFC/NOAA"@en ; "Data Center Contact"@en ; "AMSR-E"@en , "Aqua"@en , ""@en , "MEaSUREs"@en , "USA/NASA"@en ; "-89.875"^^xsd:float ; "1987-07-02"^^xsd:date ; "2011-12-31"^^xsd:date ; "12 Hour"@en ; "OCEAN WINDS"@en ; "OCEANS"@en ; "NONE"@en ; "SURFACE WINDS"@en ; "1.0"^^xsd:float ; "0.0"^^xsd:float . a base: ; owl:versionInfo "2020-09-16T19:36:14.585Z" , "2020-09-16T19:36:14.530Z" ; "Version 5.0 Aquarius CAP Level 3 products are the fourth release of the AQUARIUS/SAC-D mapped salinity and wind speed data based on the Combined Active Passive (CAP) algorithm. CAP Level 3 standard mapped image products contain gridded 1 degree spatial resolution salinity and wind speed data averaged over 7 day and monthly time scales. This particular dataset is the monthly sea surface salinity (SSS) V5.0 Aquarius CAP product. CAP is a P.I. produced dataset developed and provided by JPL. The CAP algorithm utilizes data from both the onboard radiometer and scatterometer to simultaneously retrieve salinity, wind speed and direction by minimizing the sum of squared differences between model and observations. The main improvements in CAP V5.0 relative to the previous version include: updates to the Geophysical Model Functions to 4th order harmonics with the inclusion of sea surface temperature (SST) and stability at air-sea interface effects; use of the Canadian Meteorological Center (CMC) SST product as the new source ancillary sea surface temperature data in place of NOAA OI SST. The Aquarius instrument is onboard the AQUARIUS/SAC-D satellite, a collaborative effort between NASA and the Argentinian Space Agency Comision Nacional de Actividades Espaciales (CONAE). The instrument consists of three radiometers in push broom alignment at incidence angles of 29, 38, and 46 degrees incidence angles relative to the shadow side of the orbit. Footprints for the beams are: 76 km (along-track) x 94 km (cross-track), 84 km x 120 km and 96km x 156 km, yielding a total cross-track swath of 370 km. The radiometers measure brightness temperature at 1.413 GHz in their respective horizontal and vertical polarizations (TH and TV). A scatterometer operating at 1.26 GHz measures ocean backscatter in each footprint that is used for surface roughness corrections in the estimation of salinity. The scatterometer has an approximate 390km swath."@en ; "NONE"@en ; "EARTH SCIENCE"@en ; "2020-09-16"^^xsd:date ; "Dataset Creation via Metadata Tool"@en ; "https://podaac.jpl.nasa.gov/" ; "English"@en ; "Simon Yueh"@en ; "JPL - Simon Yueh"@en ; "2018-10-01"^^xsd:date ; "Jet Propulsion Laboratory, 4800 Oak Grove Drive, Pasadena, CA91109, USA"@en ; "Aquarius CAP Sea Surface Salinity and Wind Products"@en ; "Aquarius CAP Sea Surface Salinity and Wind Products"@en ; "180.0"^^xsd:float ; "podaac@podaac.jpl.nasa.gov"@en ; "PODAAC-AQR50-3TMCS" ; "Aquarius CAP Level 3 Sea Surface Salinity Standard Mapped Image Monthly Data V5.0"@en ; ""@en ; "Oceans"@en , "Geoscientific Information"@en ; "2018-08-22"^^xsd:date ; ""@en ; "1.0"^^xsd:float ; "Geographic Region"@en ; "Global"@en ; "Aquarius Radiometer"@en , "Aquarius Scatterometer"@en , "AQUARIUS SAC-D"@en , ""@en , "Aquarius SAC-D"@en ; "1.0"^^xsd:float ; "0.0"^^xsd:float ; "0.0"^^xsd:float ; "CEOS IDN DIF"@en ; "9.8"^^xsd:float ; "0.0"^^xsd:float ; "0.0"^^xsd:float ; "90.0"^^xsd:float ; "http://podaac.jpl.nasa.gov/SeaSurfaceSalinity/Aquarius" ; "Aquarius Project NASA/CONAE, JPL"@en ; "Data Center Contact"@en ; "AQUARIUS_RADIOMETER"@en , "USA/NASA"@en , "AQUARIUS SAC-D"@en , ""@en , "AQUARIUS_SCATTEROMETER"@en , "Aquarius_SAC-D"@en ; "-90.0"^^xsd:float ; "2011-09-01"^^xsd:date ; "2015-06-01"^^xsd:date ; "1 Month"@en ; "SALINITY/DENSITY"@en ; "OCEANS"@en ; "NONE"@en ; "SALINITY"@en ; "5.0"^^xsd:float ; "-180.0"^^xsd:float . a base: ; owl:versionInfo "2020-09-16T19:36:14.540Z" , "2020-09-16T19:36:14.591Z" ; "FOR EXPERT USE ONLY. This dataset contains estimates of ocean bottom pressure derived from the Gravity Recovery and Climate Experiment (GRACE) mission measurements, produced by the NASA Jet Propulsion Laboratory (JPL). The data are in spherical harmonics averaged over approximately a month. The primary objective of the GRACE mission is to obtain accurate estimates of the mean and time-variable components of the gravity field variations. This objective is achieved by making continuous measurements of the change in distance between twin spacecraft, co-orbiting in about 500 km altitude, near circular, polar orbit, spaced approximately 200 km apart, using a microwave ranging system. In addition to these range change, the non-gravitional forces are measured on each satellite using a high accuracy electrostatic, room-temperature accelerometer. The satellite orientation and position (and timing) are precisely measured using twin star cameras and a GPS receiver, respectively. Spatial and temporal variations in the gravity field affect the orbits (or trajectories) of the twin spacecraft differently. These differences are manifested as changes in the distance between the spacecraft, as they orbit the Earth. This change in distance is reflected in the time-of-flight of microwave signals transmitted and received nearly simultaneously between the two spacecraft. The change in this time of fight is continuously measured by tracking the phase of the microwave carrier signals. The so called dual-one-way range change measurements can be reconstructed from these phase measurements. This range change (or its numerically derived derivatives), along with other mission and ancillary data, is subsequently analyzed to extract the parameters of an Earth gravity field model."@en ; "none"@en ; "EARTH SCIENCE"@en ; "2020-09-16"^^xsd:date ; "Dataset Creation via Metadata Tool"@en ; "https://podaac.jpl.nasa.gov/" ; "English"@en ; "GRACE"@en ; "JPL"@en ; "2018-07-05"^^xsd:date ; "JPL PO.DAAC"@en ; "GRACE Ocean Bottom Geopotential Coefficients JPL (GAD)"@en ; "GRACE_GAD_L2_GRAV_JPL_RL06"@en ; "180.0"^^xsd:float ; "podaac@podaac.jpl.nasa.gov"@en ; "PODAAC-GRGAD-20J06" ; "GRACE OCEAN BOTTOM GEOPOTENTIAL COEFFICIENTS JPL RELEASE 6.0 GAD"@en ; ""@en ; "Oceans"@en , "Geoscientific Information"@en ; "2018-06-11"^^xsd:date ; ""@en ; "Geographic Region"@en ; "Global"@en ; "GRACE SuperSTAR Accelerometer"@en , "Gravity Recovery and Climate Experiment"@en , "GRACE K-Band Ranging System"@en , ""@en , "Star Camera Assembly"@en ; "CEOS IDN DIF"@en ; "9.8"^^xsd:float ; "88.0"^^xsd:float ; "https://podaac-tools.jpl.nasa.gov/drive/files/allData/grace/docs/" ; "GRACE/JPL"@en ; "Data Center Contact"@en ; "GRACE"@en , "USA/NASA"@en , ""@en , "GRACE SCA"@en , "GRACE KBR"@en , "GRACE ACC"@en ; "-88.0"^^xsd:float ; "2002-04-04"^^xsd:date ; "2017-06-30"^^xsd:date ; "GRAVITY/GRAVITATIONAL FIELD"@en ; "SOLID EARTH"@en ; "none"@en ; "GRAVITY"@en ; "6.0"^^xsd:float ; "-180.0"^^xsd:float . a base: ; owl:versionInfo "2020-09-16T19:36:14.432Z" ; "Sea Surface Temperatures (SSTs) are derived from the series of Geostationary Environmental Satellites using GOES Imagers with five-band multispectral capability,10 bit precision and high spatial resolution.The GOES 6km Near Real-Time data set consists of Level 3 SSTs derived from GOES East and GOES West with a spatial resolution of approximately 6km.

In addition to wind speed and direction, the instrument can also measure sea surface temperature, soil moisture, ice and snow characteristics, water vapor, cloud liquid water, and rain rate. Unlike previous radiometers, the WindSat sensor takes observations during both the forward and aft looking scans. This makes the WindSat geometry of the earth view swath quite different and significantly more complicated to work with than the other passive microwave sensors. The Remote Sensing Systems (RSS, or REMSS) WindSat products are the only dataset available that uses both the fore and aft look directions. By using both directions, a wider swath and more complicated swath geometry is obtained. RSS providers of these SST data for the Group for High Resolution Sea Surface Temperature (GHRSST) Project, performs a detailed processing of WindSat instrument data in two stages. The first stage produces a near-real-time (NRT) product (identified by \"rt\" within the file name) which is made as available as soon as possible. This is generally within 3 hours of when the data are recorded. Although suitable for many timely uses the NRT products are not intended to be archive quality. \"Final\" data (currently identified by \"v7.0.1a\" within the file name) are processed when RSS receives the atmospheric mode NCEP FNL analysis. The NCEP wind directions are particularly useful for retrieving more accurate SSTs and wind speeds.

Terra was launched by NASA on December 18, 1999, into a sun synchronous, polar orbit with a daylight descending node at 10:30 am, to study the global dynamics of the Earth atmosphere, land and oceans. The MODIS captures data in 36 spectral bands at a variety of spatial resolutions. Two SST products can be present in these files. The first is a skin SST produced for both day and night observations, derived from the long wave IR 11 and 12 micron wavelength channels, using a modified nonlinear SST algorithm intended to provide continuity with SST derived from heritage and current NASA sensors. At night, a second SST product is produced using the mid-infrared 3.95 and 4.05 micron channels which are unique to MODIS; the SST derived from these measurements is identified as SST4. The SST4 product has lower uncertainty, but due to sun glint can only be produced at night. To generate the L3 products the L2 pixels are binned into an integerized sinusoidal area grid (ISEAG) and mapped into an equidistant cylindrical (also known as Platte Carre) projection.

It was launched on 1 Mar 2018 in an interim position at 89.5-deg W for initial Cal/Val, moved to its nominal position at 137.2-deg W in Nov 2018, and declared NOAA operational GOES-West satellite on 12 Feb 2019. Advanced Baseline Imager (ABI) is a 16 channel sensor, of which five (3.9, 8.4, 10.3, 11.2, 12.3 um) are suitable for SST. From altitude 35,800km, G17/ABI maps SST in a Full Disk (FD) area from 163E-77W and 60S-60N, with spatial resolution 2km/nadir to 15km/VZA 67-deg, and 10-min temporal sampling. The ABI L2P SST is derived at the native sensor resolution using NOAA ACSPO system. ACSPO processes every 10-min FD, identifies good-quality ocean pixels (Petrenko et al., 2010) and derives SST using Non-Linear SST (NLSST) algorithm (Petrenko et al., 2014). Unfortunately, the G17 ABI loop heat pipe (LHP) that should maintain the ABI at its intended temperature, is not operating at its designed capacity, which required mitigations to the ACSPO algorithms and releasing an updated ACSPO version 2.71 (Pennybacker et al, 2019). In particular, band 11.2um, most subject to calibration problems, is not used leading to a 3-band (8.4, 10.3, and 12.3um) NLSST, and increased calibration problems prevent SST retrievals at night. As a result, the G17 SST is only reported for 13 out of 24hrs/day, from 20UTC to 08UTC. The 10-min FD data are subsequently collated in time, to produce 1-hr product, with improved coverage and reduced cloud leakages and image noise. The collation algorithm also reduces G17 excessive sensor noise and striping to levels similar to G16. The collated SSTs are only reported over clear-sky water pixels. All pixels with valid SSTs are recommended for use. The L2P is reported in NetCDF4 GDS2 format, 13 granules per day, with a total data volume 0.3GB/day. ACSPO files also report sun-sensor geometry, wind speed and l2p_flags (day/night, land, ice, twilight, glint flags). Per GDS2 specifications, two Sensor-Specific Error Statistics (bias and standard deviation) are reported in each pixel (Petrenko et al., 2016). Pixel earth locations are not reported in the granules, as they remain unchanged from granule to granule. Those can be obtained using a flat lat/lon file or a Python script available at https://podaac-tools.jpl.nasa.gov/drive/files/allData/ghrsst/data/GDS2/L2P/GOES17/STAR/nav. The ACSPO G17 ABI SSTs are continuously validated in SQUAM (Dash et al, 2010).

The retrievals are provided on a non-uniform grid within the swath at 12.5 km pixel resolution. Higher resolution is achieved through a slice composite technique in which high resolution slice measurements from L1B data are composited into a 12.5 km wind vector cell. Each L2B file corresponds to a specific orbital revolution (rev) number, which begins at the southernmost point of the ascending orbit. This is an official dataset produced by the NASA QuikSCAT Project through the SeaWinds Processing and Analysis Center (SeaPAC). Version 4.1 processing begins with the same L1B (time-ordered backscatter) data as used in the previous Version 4.0 processing. This new version has a number of key improvements and changes over the previous version 4.0, including: 1) winds are now retrieved to within 5-km and 10-km of the coast within oceans/seas and lakes respectively; 2) coastal winds are now flagged as poor coastal quality and likely corrupted in orbits with estimated spacecraft pitch error greater than 0.04 degrees, which affects 150 orbits of data where coastal winds are severely contaminated by land due to poor attitude knowledge (note: attitude error tracking can identify pitch error but not yaw error, so when estimated pitch error is far from zero, it implies yaw error is large and uncorrected); 3) coastal winds are flagged based upon the long term mean wind speed and standard deviation of wind speed for each place on the ground; 4) four quantities, means and standard deviations computed with and without the land contamination correction algorithm applied (note: higher mean and smaller standard deviation are evidence of land contamination), are used to estimate the expected wind speed bias with respect to neighboring wind vector cells over open water; 5) wind vector cells with estimated speed bias greater than 0.4 m/s are flagged as poor coastal quality and likely corrupted; 6) winds within 5-km of the coast of an ocean/sea and 10-km of the coast of a lake are flagged as poor coastal quality and likely corrupted; the larger distance threshold for lakes is due to higher variability in lake water levels."@en ; "NONE"@en ; "EARTH SCIENCE"@en ; "2020-09-16"^^xsd:date ; "Dataset Creation via Metadata Tool"@en ; "https://podaac.jpl.nasa.gov/" ; "English"@en ; "SeaPAC"@en ; "SeaPAC"@en ; "2020-09-04"^^xsd:date ; "PO.DAAC"@en ; "QuikSCAT Level 2B Ocean Wind Vectors in 12.5km Slice Composites"@en ; "QuikSCAT Level 2B Ocean Wind Vectors in 12.5km Slice Composites Version 4.1"@en ; "360.0"^^xsd:float ; "podaac@podaac.jpl.nasa.gov"@en ; "PODAAC-QSX12-L2B41" ; "QuikSCAT Level 2B Ocean Wind Vectors in 12.5km Slice Composites Version 4.1"@en ; ""@en ; "Geoscientific Information"@en , "Oceans"@en ; "2020-07-29"^^xsd:date ; ""@en ; "Geographic Region"@en ; "Global"@en ; ""@en , "Quick Scatterometer"@en , "SeaWinds Scatterometer"@en , "QUIKSCAT"@en ; "CEOS IDN DIF"@en ; "9.8"^^xsd:float ; "90.0"^^xsd:float ; "https://podaac-tools.jpl.nasa.gov/drive/files/allData/quikscat/L2B12/docs/" ; "NASA/JPL/SeaPAC"@en ; "Data Center Contact"@en ; "SEAWINDS"@en , "USA/NASA"@en , ""@en , "QUIKSCAT"@en ; "-90.0"^^xsd:float ; "1999-10-27"^^xsd:date ; "2009-11-22"^^xsd:date ; "OCEAN WINDS"@en ; "OCEANS"@en ; "NONE"@en ; "SURFACE WINDS"@en ; "4.1"^^xsd:float ; "0.0"^^xsd:float . a base: ; owl:versionInfo "2020-09-16T19:36:14.487Z" ; "Aquarius Level 3 ancillary sea surface temperature (SST) standard mapped image data are the ancillary SST data used in the Aquarius calibration for salinity retrieval.

Average daily, weekly (8 day), monthly and annual skin SST products at are available at both 4.63 and 9.26 km spatial resolution. Aqua was launched by NASA on May 4, 2002, into a sun synchronous, polar orbit with a daylight ascending node at 13:30, formation flying in the A-train with other Earth Observation Satellites (EOS), to study the global dynamics of the Earth atmosphere, land and oceans. MODIS captures data in 36 spectral bands at a variety of spatial resolutions. Two SST products can be present in these files. The first is a skin SST produced for both day and night (NSST) observations, derived from the long wave IR 11 and 12 micron wavelength channels, using a modified nonlinear SST algorithm intended to provide continuity of SST derived from heritage and current NASA sensors. At night, a second SST product is generated using the mid-infrared 3.95 and 4.05 micron wavelength channels which are unique to MODIS; the SST derived from these measurements is identified as SST4. The SST4 product has lower uncertainty, but due to sun glint can only be used at night. To generate the L3 products the L2 pixels are binned into an integerized sinusoidal area grid (ISEAG) and mapped into an equidistant cylindrical (also known as Platte Carre projection. Additional projection detailed can be found at https://oceancolor.gsfc.nasa.gov/docs/format/The NASA MODIS L3 SST data products are generated by the NASA Ocean Biology Processing Group (OBPG) and Peter Minnett and his team at the Rosenstiel School of Marine and Atmospheric Science (RSMAS) are responsible for sea surface temperature algorithm development, error statistics and quality flagging.

These data are provided in a single data file in netCDF format, and can be used for analysis for ocean, ice, and hydrology phenomena. The water storage/height anomalies are given in equivalent water thickness units (cm). The solution provided here is derived from solving for monthly gravity field variations in terms of geolocated spherical cap mass concentration functions, rather than global spherical harmonic coefficients. Additionally, realistic geophysical information is introduced during the solution inversion to intrinsically remove correlated error. Thus, these Mascon grids do not need to be destriped or smoothed, like traditional spherical harmonic gravity solutions. The complete Mascon solution consists of 4,551 relatively independent estimates of surface mass change that have been derived using an equal-area 3-degree grid of individual mascons. It should be noted that this dataset does not correct for leakage errors across coastlines; it is therefore recommended only for users who want to apply their own algorithm to separate between land and ocean mass very near coastlines. Please refer to the 'Data Access' tab at the top of this page to gain direct access to the Mascon data.

The SIR technique results in an enhanced resolution image reconstruction and gridded on an equal-area grid (for non-polar regions) at 8.9 km pixel resolution stored in SIR files; polar regions are gridded at the same resolution using a polar-stereographic technique. A non-enhanced version is provided at 44.5 km pixel resolution in a format known as GRD (i.e., gridded) files. All files are produced in IEEE formatted binary. All data files are separated and organized by region, parameter, and sampling technique (i.e., SIR vs. GRD). The regions of China and Japan are combined into a single region. In addition to Sigma-0, various statistical parameters are provided for added guidance, including but not limited to: standard deviation, measurement counts, pixel time, Sigma-0 error, and average incidence angle. This dataset was once distributed on tape, but has been made available on FTP thanks to the BYU SCP.

Over the oceans, AMSR-E is measuring a number of important geophysical parameters, including sea surface temperature (SST), wind speed, atmospheric water vapor, cloud water, and rain rate. A key feature of AMSR-E is its capability to see through clouds, thereby providing an uninterrupted view of global SST and surface wind fields.

The AVHRR is a space-borne scanning sensor on the National Oceanic and Atmospheric Administration (NOAA) family of Polar Orbiting Environmental Satellites (POES) having a operational legacy that traces back to the Television Infrared Observation Satellite-N (TIROS-N) launched in 1978. AVHRR instruments measure the radiance of the Earth in 5 (or 6) relatively wide spectral bands. The first two are centered around the red (0.6 micrometer) and near-infrared (0.9 micrometer) regions, the third one is located around 3.5 micrometer, and the last two sample the emitted thermal radiation, around 11 and 12 micrometers, respectively. The legacy 5 band instrument is known as AVHRR/2 while the more recent version, the AVHRR/3 (first carried on the NOAA-15 platform), acquires data in a 6th channel located at 1.6 micrometer. Typically the 11 and 12 micron channels are used to derive SST sometimes in combination with the 3.5 micron channel. The NOAA platforms are sun synchronous generally viewing the same earth location twice a day (latitude dependent) due to the relatively large AVHRR swath of approximately 2400 km. The highest ground resolution that can be obtained from the current AVHRR instruments is 1.1 km at nadir. AVHRR data are acquired in three formats: High Resolution Picture Transmission (HRPT), Local Area Coverage (LAC), and Global Area Coverage (GAC). HRPT data are full resolution image data transmitted to a ground stations as they are collected. LAC are also full resolution data, but the acquisition is prescheduled and recorded with an on-board tape recorder for subsequent transmission during a station overpass. This particular dataset is produced from GAC data that are derived from an on-board sample averaging of the full resolution global AVHRR data. Four out of every five samples along the scan line are used to compute on average value and the data from only every third scan line are processed, yielding an effective 4 km resolution at nadir. Further binning and averaging of these pixels results in a final dataset resolution of 8.8 km."@en ; "None"@en ; "EARTH SCIENCE"@en ; "2020-09-16"^^xsd:date ; "Dataset Creation via Metadata Tool"@en ; "https://podaac.jpl.nasa.gov/" ; "English"@en ; "Naval Oceanographic Office"@en ; "Naval Oceanographic Office"@en ; "2014-10-27"^^xsd:date ; "Stennis Space Center, MS, USA"@en ; "GHRSST Level 2P Global 1m Sea Surface Temperature from the Advanced Very High Resolution Radiometer (AVHRR) on the NOAA-19 satellite produced by NAVO"@en ; "N-19 AVHRR GAC L2P swath SST data set"@en ; "180.0"^^xsd:float ; "podaac@podaac.jpl.nasa.gov"@en ; "PODAAC-GH19G-2PN02" ; "GHRSST Level 2P Global 1m Sea Surface Temperature from the Advanced Very High Resolution Radiometer (AVHRR) on the NOAA-19 satellite produced by NAVO"@en ; ""@en ; "Oceans"@en , "Geoscientific Information"@en ; "2017-04-28"^^xsd:date ; ""@en ; "Geographic Region"@en ; "Global"@en ; "National Oceanic & Atmospheric Administration-19"@en , "Group for High Resolution Sea Surface Temperature"@en , "Advanced Very High Resolution Radiometer"@en , ""@en ; "CEOS IDN DIF"@en ; "9.8"^^xsd:float ; "80.0"^^xsd:float ; "" ; "Naval Oceanographic Office"@en ; "Data Center Contact"@en ; "NOAA-19"@en , "AVHRR"@en , "USA/NASA"@en , ""@en , "GHRSST"@en ; "-70.0"^^xsd:float ; "2013-09-24"^^xsd:date ; "OCEAN TEMPERATURE"@en ; "OCEANS"@en ; "None"@en ; "SEA SURFACE TEMPERATURE"@en ; "1.0"^^xsd:float ; "-180.0"^^xsd:float . a owl:DatatypeProperty . a base: ; owl:versionInfo "2020-09-16T19:36:14.422Z" ; "The Jason-1 Geophysical Data Records (GDR) contain full accuracy altimeter data to measure sea surface height, with a high precision orbit (accuracy ~1.5 cm).

The CCMP datasets combine cross-calibrated satellite winds obtained from Remote Sensing Systems (REMSS) using a Variational Analysis Method (VAM) to produce a high-resolution (0.25 degree) gridded analysis. Wind directions from the resulting analysis are assigned to the location and time of the satellite-derived wind speed observations to create this value added dataset. The CCMP data set includes cross-calibrated satellite winds derived from SSM/I, SSMIS, AMSR-E, TRMM TMI, QuikSCAT, SeaWinds, WindSat and other satellite instruments as they become available from REMSS. REMSS uses a cross-calibrated sea-surface emissivity model function which improves the consistency between wind speed retrievals from microwave radiometers (i.e., SSM/I, SSMIS, AMSR, TMI, and WindSat) and those from scatterometers (i.e., QuikSCAT and SeaWinds). The VAM combines these data with in situ measurements and a starting estimate (first guess) of the wind field. The European Center for Medium-Range Weather Forecasts (ECMWF) ERA-40 Reanalysis is used as the first-guess from 1987 to 1998. The ECMWF Operational analysis is used from January 1999 onward. All wind observations and analysis fields are referenced to a height of 10 meters. The ERA-40 can be obtained from the Computation and Information Systems Laboratory (CISL) at the National Center for Atmospheric Research (NCAR): http://rda.ucar.edu/datasets/ds117.0/. The ECMWF Operational analysis can also be obtained from CISL at NCAR: http://rda.ucar.edu/datasets/ds111.1/. Three products are distributed to complete the CCMP dataset series. L3.0 product contains high-resolution analyses every 6-hours. These data are then time averaged over monthly and 5-day periods to derive the L3.5 product. Directions from the L3.0 product are then assigned to the time and location of the passive microwave satellite wind speed observations to derive the L2.5 product. All datasets are distributed on a 0.25 degree cylindrical coordinate grid. This dataset is one in a series of First-Look (FLK) CCMP datasets and is a continuation and expansion of the SSM/I surface wind velocity project that began under the NASA Pathfinder Program. Refinements and upgrades to the FLK version will be incorporated under a new release (date to be determined) known as Late-look (LLK) and may include additional satellite datasets. All satellite surface wind data are obtained from REMSS under the DISCOVER project: Distributed Information Services: Climate/Ocean Products and Visualizations for Earth Research (http://www.discover-earth.org/index.html). The CCMP project is the result of an investigation funded by the NASA Making Earth Science data records for Use in Research Environments (MEaSUREs) program (http://community.eosdis.nasa.gov/measures/). In accordance with the MEaSUREs program, the CCMP datasets are also known as Earth System Data Records (ESDRs). In collaboration with private and government institutions, a team led by Dr. Robert Atlas (PI; proposal originally solicited by REASoN, and currently funded by MEaSURES) has created the CCMP project to provide multi-instrument ocean surface wind velocity ESDRs, with wide ranging research applications in meteorology and oceanography."@en ; "NONE"@en ; "EARTH SCIENCE"@en ; "2020-09-16"^^xsd:date ; "Dataset Creation via Metadata Tool"@en ; "https://podaac.jpl.nasa.gov/" ; "English"@en ; "NASA/GSFC/NOAA"@en ; "PO.DAAC"@en ; "2011-08-04"^^xsd:date ; "PO.DAAC"@en ; "Cross-Calibrated Multi-Platform Ocean Surface Wind Vector L2.5 First-Look SSMIS-F17 Microwave Analyses"@en ; "Cross-Calibrated Multi-Platform Ocean Surface Wind Vector L2.5 First-Look SSMIS-F17 Microwave Analyses"@en ; "360.0"^^xsd:float ; "podaac@podaac.jpl.nasa.gov"@en ; "PODAAC-CCF25-01F17" ; "Cross-Calibrated Multi-Platform Ocean Surface Wind Vector L2.5 First-Look SSMIS-F17 Microwave Analyses"@en ; ""@en ; "Oceans"@en , "Geoscientific Information"@en ; "2011-08-05"^^xsd:date ; ""@en ; "0.25"^^xsd:float ; "Geographic Region"@en ; "Global"@en ; "Defense Meteorological Satellite Program-F17"@en , "Special Sensor Microwave Imager/Sounder"@en , ""@en , "Making Earth Science Data Records for Use in Research Environments"@en ; "0.25"^^xsd:float ; "CEOS IDN DIF"@en ; "9.8"^^xsd:float ; "89.875"^^xsd:float ; "https://podaac-tools.jpl.nasa.gov/drive/files/allData/ccmp/L2.5/docs/ccmp_users_guide.pdf" ; "NASA/GSFC/NOAA"@en ; "Data Center Contact"@en ; "DMSP 5D-3/F17"@en , ""@en , "MEaSUREs"@en , "SSMIS"@en , "USA/NASA"@en ; "-89.875"^^xsd:float ; "2010-01-01"^^xsd:date ; "2011-12-31"^^xsd:date ; "12 Hour"@en ; "OCEAN WINDS"@en ; "OCEANS"@en ; "NONE"@en ; "SURFACE WINDS"@en ; "1.0"^^xsd:float ; "0.0"^^xsd:float . a base: ; owl:versionInfo "2020-09-16T19:36:14.287Z" ; "The Moderate-resolution Imaging Spectroradiometer (MODIS) is a scientific instrument (radiometer) on board the NASA Terra and Aqua satellite platforms, launched in 1999 and 2002 respectively to study global dynamics of the Earths atmosphere, land, ice and oceans.

This dataset contains estimates of the total month-by-month geopotential of the Earth, derived from the Gravity Recovery and Climate Experiment Follow-On (GRACE-FO) mission measurements, produced by the German Research Centre for Geosciences (GFZ). The data are provided in spherical harmonic coefficients, averaged over approximately a month. The primary objective of the GRACE-FO mission is to obtain accurate estimates of the mean and time-variable components of the gravity field and corresponding Earth mass change variations, such as from polar ice sheets and mountain glaciers; total water storage on land (from groundwater changes in deep aquifers to changes in soil moisture and surface water); changes in deep ocean currents; and changes within the solid Earth itself, such as postglacial rebound and the impact of major earthquakes. This objective is achieved by making continuous measurements of the change in distance between twin spacecraft, co-orbiting in about 490 km altitude, near circular, polar orbit, spaced approximately 220+/-50 km apart, using a microwave ranging system. In addition to these inter-satellite range changes, the non-gravitational forces acting on each satellite are measured using a high accuracy electrostatic accelerometer. The satellite orientation and position (and timing) are precisely measured using star cameras (with three heads per satellite) and a GPS receiver. Spatial and temporal variations in the gravity field perturb the orbits (or trajectories) of the twin spacecraft differently. These differences lead to minute changes (on the order of tens of micrometers per second) in the distance between the spacecraft as they orbit the Earth. This change in distance (or range rate) is reflected in the time-of-flight of microwave signals transmitted and received nearly simultaneously between the two spacecraft. The change in this time of fight is continuously measured by tracking the phase of the microwave carrier signals. The so called dual-one-way range change measurements can be reconstructed from these phase measurements. This range change (or its numerically derived derivatives), along with other mission and ancillary data, is subsequently analyzed to extract the geopotential coefficients of an Earth gravity field model, typically on a per-month basis."@en ; "none"@en ; "EARTH SCIENCE"@en ; "2020-09-16"^^xsd:date ; "Dataset Creation via Metadata Tool"@en ; "https://podaac.jpl.nasa.gov/" ; "English"@en ; "GRACE-FO"@en ; "JPL"@en ; "2019-06-10"^^xsd:date ; "JPL"@en ; "GRACE-FO Level-2 Monthly Geopotential Spherical Harmonics GFZ"@en ; "GRACEFO_L2_GFZ_MONTHLY_0060"@en ; "180.0"^^xsd:float ; "podaac@podaac.jpl.nasa.gov"@en ; "PODAAC-GFL20-MG060" ; "GRACE-FO Level-2 Monthly Geopotential Spherical Harmonics GFZ Release 6.0 (RL06)"@en ; ""@en ; "Geoscientific Information"@en , "Oceans"@en ; "2017-10-04"^^xsd:date ; ""@en ; "Geographic Region"@en ; "Global"@en ; "GRACE-FO K-Band Ranging System"@en , "GRACE-FO SuperSTAR Accelerometer"@en , "GRACE-FO Laser Ranging Interferometer"@en , "GRACE Follow-On"@en , "Gravity Recovery and Climate Experiment Follow-On"@en , "GRACE-FO Star Camera Assembly"@en , ""@en ; "CEOS IDN DIF"@en ; "9.8"^^xsd:float ; "89.0"^^xsd:float ; "https://podaac-tools.jpl.nasa.gov/drive/files/allData/gracefo/docs/" ; "GRACE-FO/GFZ"@en ; "Data Center Contact"@en ; "USA/NASA"@en , ""@en , "GRACE-FO LRI"@en , "GRACE-FO ACC"@en , "GRACE-FO KBR"@en , "GRACE-FO SCA"@en , "GRACE-FO"@en ; "-89.0"^^xsd:float ; "2018-05-22"^^xsd:date ; "Monthly"@en ; "GRAVITY/GRAVITATIONAL FIELD"@en ; "SOLID EARTH"@en ; "none"@en ; "GRAVITY"@en ; "6.0"^^xsd:float ; "-180.0"^^xsd:float . a base: ; owl:versionInfo "2020-09-16T19:36:14.453Z" ; "Aquarius Level 3 sea surface density standard mapped image data contains gridded 1 degree spatial resolution density data averaged over daily, 7 day, monthly, and seasonal time scales.

Terra was launched by NASA on December 18, 1999, into a sun synchronous, polar orbit with a daylight descending node at 10:30 am, to study the global dynamics of the Earth atmosphere, land and oceans. The MODIS captures data in 36 spectral bands at a variety of spatial resolutions. Two SST products can be present in these files. The first is a skin SST produced for both day and night observations, derived from the long wave IR 11 and 12 micron wavelength channels, using a modified nonlinear SST algorithm intended to provide continuity with SST derived from heritage and current NASA sensors. At night, a second SST product is produced using the mid-infrared 3.95 and 4.05 micron channels which are unique to MODIS; the SST derived from these measurements is identified as SST4. The SST4 product has lower uncertainty, but due to sun glint can only be produced at night. To generate the L3 products the L2 pixels are binned into an integerized sinusoidal area grid (ISEAG) and mapped into an equidistant cylindrical (also known as Platte Carre) projection.

It is based on the Combined Active-Passive (CAP) retrieval algorithm developed at JPL originally in the context of Aquarius/SAC-D and now extended to SMAP. Improvements with V4.3 include: 1) New residual TB calibration which removes the ascending/descending bias issue observed for version 4.2; 2) Slightly modified criteria for aggregation from L2B to L3 based on TB for V-pol minus TB for H-pol. The JPL SMAP-SSS L2B CAP NRT product includes data for a range of parameters: derived SMAP sea surface salinity, SSS uncertainty and wind speed/direction data for extreme winds, brightness temperatures for each radiometer polarization, ancillary reference surface salinity, ice concentration, wind and wave height data, quality flags, and navigation data. Each data file covers one 98-minute orbit (15 files per day). Data begins on April 1,2015 and is ongoing, with a 6 hour latency in processing and availability. Observations are global in extent and provided at 25km swath grid with an approximate spatial resolution of 60 km.The SMAP satellite is in a near-polar orbit at an inclination of 98 degrees and an altitude of 685 km. It has an ascending node time of 6 pm and is sun-synchronous. With its 1000km swath, SMAP achieves global coverage in approximately 3 days, but has an exact orbit repeat cycle of 8 days. On board Instruments include a highly sensitive L-band radiometer operating at 1.41GHz and an L-band 1.26GHz radar sensor providing complementary active and passive sensing capabilities.

The data are in spherical harmonics averaged over 2003-2006. The primary objective of the GRACE mission is to obtain accurate estimates of the mean and time-variable components of the Earths gravity field variations. This objective is achieved by making continuous measurements of the change in distance between twin spacecraft, co-orbiting in about 500 km altitude, near circular, polar orbit, spaced approximately 200 km apart, using a microwave ranging system. In addition to these range change, the non-gravitional forces are measured on each satellite using a high accuracy electrostatic, room-temperature accelerometer. The satellite orientation and position (and timing) are precisely measured using twin star cameras and a GPS receiver, respectively. Spatial and temporal variations in the Earths gravity field affect the orbits (or trajectories) of the twin spacecraft differently. These differences are manifested as changes in the distance between the spacecraft, as they orbit the Earth. This change in distance is reflected in the time-of-flight of microwave signals transmitted and received nearly simultaneously between the two spacecraft. The change in this time of fight is continuously measured by tracking the phase of the microwave carrier signals. The so called dual-one-way range change measurements can be reconstructed from these phase measurements. This range change (or its numerically derived derivatives), along with other mission and ancillary data, is subsequently analyzed to extract the parameters of an Earth gravity field model."@en ; "none"@en ; "EARTH SCIENCE"@en ; "2020-09-16"^^xsd:date ; "Dataset Creation via Metadata Tool"@en ; "https://podaac.jpl.nasa.gov/" ; "English"@en ; "GRACE"@en ; "CSR"@en ; "2012-03-30"^^xsd:date ; "JPL"@en ; "GRACE STATIC FIELD GEOPOTENTIAL COEFFICIENTS CSR"@en ; "GRACE_MEAN_L2_GRAV_CSR_RL05"@en ; "180.0"^^xsd:float ; "podaac@podaac.jpl.nasa.gov"@en ; "PODAAC-GRMEA-20C05" ; "GRACE STATIC FIELD GEOPOTENTIAL COEFFICIENTS AVERAGED OVER A LONG TIME SERIES CSR RELEASE 5.0"@en ; ""@en ; "Oceans"@en , "Geoscientific Information"@en ; "2013-01-16"^^xsd:date ; ""@en ; "Geographic Region"@en ; "Global"@en ; "Gravity Recovery and Climate Experiment"@en , "GRACE-FO K-Band Ranging System"@en , "Star Camera Assembly"@en , ""@en , "GRACE-FO SuperSTAR Accelerometer"@en ; "CEOS IDN DIF"@en ; "9.8"^^xsd:float ; "89.0"^^xsd:float ; "https://podaac-tools.jpl.nasa.gov/drive/files/allData/grace/L2/CSR/RL05/docs/" ; "GRACE/CSR"@en ; "Data Center Contact"@en ; "GRACE SCA"@en , "GRACE-FO ACC"@en , ""@en , "GRACE"@en , "USA/NASA"@en , "GRACE-FO KBR"@en ; "-89.0"^^xsd:float ; "2002-08-01"^^xsd:date ; "GRAVITY/GRAVITATIONAL FIELD"@en ; "SOLID EARTH"@en ; "none"@en ; "GRAVITY"@en ; "5.0"^^xsd:float ; "-180.0"^^xsd:float . a base: ; owl:versionInfo "2020-09-16T19:36:14.481Z" ; "Aquarius Level 3 ocean surface wind speed standard mapped image data contains gridded 1 degree spatial resolution wind speed data averaged over daily, 7 day, monthly, and seasonaltime scales.

Sigma-0) from the L1B dataset. RapidScat is a Ku-band dual beam circular rotating scatterometer retaining much of the same hardware and functionality of QuikSCAT, with exception of the antenna sub-system and digital interface to the International Space Station (ISS) Columbus module, which is where RapidScat is mounted. The NASA mission is officially referred to as ISS-RapidScat. Unlike QuikSCAT, ISS-RapidScat is not in sun-synchronous orbit, and flies at roughly half the altitude with a low inclination angle that restricts data coverage to the tropics and mid-latitude regions; the extent of latitudinal coverage stretches from approximately 61 degrees North to 61 degrees South. Furthermore, there is no consistent local time of day retrieval. The new version has two important improvements over the previous version 1.0. First, an SST-dependent GMF developed by Lucrezia Ricciardulli of Remote Sensing Systems is used in wind retrieval in order to fix persistent speed biases in Ku-band data over cold ocean. Second, flagging is simplified and extra flags are provided. All the previously existing flags are still there and still reflect the same meaning and purpose. A new single bit wind_retrieval_likely_corrupted_flag specifies the approximately 3% of the data which is known to have suboptimal performance due to rain, ice, or a few other rare anomalous cases. Another bit wind_retrieval_possibly_corrupted_flag specifies the approximately 15% of the data near rain, near ice, or near the coast, that is thought to be high quality but may not match up well with numerical wind models due to either remaining rain/ice/land contamination or variability in the winds near ice, rain, and coasts that are not reflected in the NWPs. In addition to these two new bits, copious quality information is provided in the data to allow users to tailor flags to meet their own needs. There is also an added a global attribute called rev_status that specifies whether the RapidScat Instrument was in the original (highest data quality) high SNR mode, or one of the four low SNR time periods, the latter of which indicates the accuracy of winds below 5 m/s is degraded. This attribute also serves to identify MARGINAL orbits in which there are large gaps in the data record due to suboptimal spacecraft attitude. Other than gaps in the data, the accuracy of the winds in the MARGINAL orbits are similar to other orbits. This dataset is provided in netCDF-4 format and made available via FTP and OPeNDAP.

Average daily, weekly (8 day), monthly and annual skin SST products at are available at both 4.63 and 9.26 km spatial resolution. Aqua was launched by NASA on May 4, 2002, into a sun synchronous, polar orbit with a daylight ascending node at 13:30, formation flying in the A-train with other Earth Observation Satellites (EOS), to study the global dynamics of the Earth atmosphere, land and oceans. MODIS captures data in 36 spectral bands at a variety of spatial resolutions. Two SST products can be present in these files. The first is a skin SST produced for both day and night (NSST) observations, derived from the long wave IR 11 and 12 micron wavelength channels, using a modified nonlinear SST algorithm intended to provide continuity of SST derived from heritage and current NASA sensors. At night, a second SST product is generated using the mid-infrared 3.95 and 4.05 micron wavelength channels which are unique to MODIS; the SST derived from these measurements is identified as SST4. The SST4 product has lower uncertainty, but due to sun glint can only be used at night. To generate the L3 products the L2 pixels are binned into an integerized sinusoidal area grid (ISEAG) and mapped into an equidistant cylindrical (also known as Platte Carre projection. Additional projection detailed can be found at https://oceancolor.gsfc.nasa.gov/docs/format/The NASA MODIS L3 SST data products are generated by the NASA Ocean Biology Processing Group (OBPG) and Peter Minnett and his team at the Rosenstiel School of Marine and Atmospheric Science (RSMAS) are responsible for sea surface temperature algorithm development, error statistics and quality flagging.

The inner beam is horizontally polarized while the outer beam is vertically polarized. The SIR files are separated according to polarization.

This dataset contains estimates of the total month-by-month geopotential of the Earth, derived from the Gravity Recovery and Climate Experiment Follow-On (GRACE-FO) mission measurements, produced by the Center for Space Research (CSR) at University of Texas at Austin. The data are provided in spherical harmonic coefficients, averaged over approximately a month. The primary objective of the GRACE-FO mission is to obtain accurate estimates of the mean and time-variable components of the gravity field and corresponding Earth mass change variations, such as from polar ice sheets and mountain glaciers; total water storage on land (from groundwater changes in deep aquifers to changes in soil moisture and surface water); changes in deep ocean currents; and changes within the solid Earth itself, such as postglacial rebound and the impact of major earthquakes. This objective is achieved by making continuous measurements of the change in distance between twin spacecraft, co-orbiting in about 490 km altitude, near circular, polar orbit, spaced approximately 220+/-50 km apart, using a microwave ranging system. In addition to these inter-satellite range changes, the non-gravitational forces acting on each satellite are measured using a high accuracy electrostatic accelerometer. The satellite orientation and position (and timing) are precisely measured using star cameras (with three heads per satellite) and a GPS receiver. Spatial and temporal variations in the gravity field perturb the orbits (or trajectories) of the twin spacecraft differently. These differences lead to minute changes (on the order of tens of micrometers per second) in the distance between the spacecraft as they orbit the Earth. This change in distance (or range rate) is reflected in the time-of-flight of microwave signals transmitted and received nearly simultaneously between the two spacecraft. The change in this time of fight is continuously measured by tracking the phase of the microwave carrier signals. The so called dual-one-way range change measurements can be reconstructed from these phase measurements. This range change (or its numerically derived derivatives), along with other mission and ancillary data, is subsequently analyzed to extract the geopotential coefficients of an Earth gravity field model, typically on a per-month basis."@en ; "none"@en ; "EARTH SCIENCE"@en ; "2020-09-16"^^xsd:date ; "Dataset Creation via Metadata Tool"@en ; "https://podaac.jpl.nasa.gov/" ; "English"@en ; "GRACE-FO"@en ; "JPL"@en ; "2019-06-10"^^xsd:date ; "JPL"@en ; "GRACE-FO Level-2 Monthly Geopotential Spherical Harmonics CSR"@en ; "GRACEFO_L2_CSR_MONTHLY_0060"@en ; "180.0"^^xsd:float ; "podaac@podaac.jpl.nasa.gov"@en ; "PODAAC-GFL20-MC060" ; "GRACE-FO Level-2 Monthly Geopotential Spherical Harmonics CSR Release 6.0 (RL06)"@en ; ""@en ; "Geoscientific Information"@en , "Oceans"@en ; "2017-10-04"^^xsd:date ; ""@en ; "Geographic Region"@en ; "Global"@en ; "Gravity Recovery and Climate Experiment Follow-On"@en , "GRACE-FO Star Camera Assembly"@en , "GRACE-FO Laser Ranging Interferometer"@en , "GRACE-FO SuperSTAR Accelerometer"@en , "GRACE-FO K-Band Ranging System"@en , ""@en , "GRACE Follow-On"@en ; "CEOS IDN DIF"@en ; "9.8"^^xsd:float ; "89.0"^^xsd:float ; "https://podaac-tools.jpl.nasa.gov/drive/files/allData/gracefo/docs/" ; "GRACE-FO/JPL"@en ; "Data Center Contact"@en ; "GRACE-FO ACC"@en , "GRACE-FO LRI"@en , "GRACE-FO SCA"@en , "GRACE-FO KBR"@en , ""@en , "GRACE-FO"@en , "USA/NASA"@en ; "-89.0"^^xsd:float ; "2018-05-22"^^xsd:date ; "Monthly"@en ; "GRAVITY/GRAVITATIONAL FIELD"@en ; "SOLID EARTH"@en ; "none"@en ; "GRAVITY"@en ; "6.0"^^xsd:float ; "-180.0"^^xsd:float . a base: ; owl:versionInfo "2020-09-16T19:36:14.526Z" , "2020-09-16T19:36:14.582Z" ; "The monthly land mass grids contain water mass anomalies given as equivalent water thickness derived from GRACE & GRACE-FO time-variable gravity observations during the specified timespan, and relative to the specified time-mean reference period.

Average daily, weekly (8 day), monthly and annual skin SST products are available at both 4.63 and 9.26 km spatial resolution. Terra was launched by NASA on December 18, 1999, into a sun synchronous, polar orbit with a daylight descending node at 10:30 am, to study the global dynamics of the Earth atmosphere, land and oceans. The MODIS captures data in 36 spectral bands at a variety of spatial resolutions. Two SST products can be present in these files. The first is a skin SST produced for both day and night observations, derived from the long wave IR 11 and 12 micron wavelength channels, using a modified nonlinear SST algorithm intended to provide continuity with SST derived from heritage and current NASA sensors. At night, a second SST product is produced using the mid-infrared 3.95 and 4.05 micron channels which are unique to MODIS; the SST derived from these measurements is identified as SST4. The SST4 product has lower uncertainty, but due to sun glint can only be produced at night. To generate the L3 products the L2 pixels are binned into an integerized sinusoidal area grid (ISEAG) and mapped into an equidistant cylindrical (also known as Platte Carre) projection.

The drone is autonomous in that it may be guided remotely from land while being completely wind driven. The saildrone Baja campaign was a 60-day cruise from San Francisco Bay, down along the US/Mexico coast to Guadalupe Island and back again over the period 11 April 2018 to 11 June 2018. Repeat surveys were taken around NDBC moored buoys, and during the final week of the cruise a targeted front was sampled. Scientific objectives included studies of upwelling and frontal region dynamics, air-sea interactions, and diurnal warming effects, while its validation objectives included establishing the utility of data from the saildrone platform for assessment of satellite data accuracy and model assimilation. During the Baja campaign, the single deployed saildrone was equipped with a suite of instruments that included a CTD, IR pyrometer, fluorometer, dissolved oxygen sensor, anemometer, barometer, and Acoustic Doppler Current Profiler (ADCP). Additionally, four temperature data loggers were positioned vertically along hull to provide further information on thermal variability near the ocean surface.This Saildrone Baja dataset is comprised of one data file with the saildrone platform telemetry and near-surface observational data (air temperature, sea surface skin and bulk temperatures, salinity, oxygen and chlorophyll-a concentrations, barometric pressure, wind speed and direction) for the entire cruise at 1 minute temporal resolution. A second file contains the ADCP current vector data that is depth-resolved to 100m at 2m intervals and binned temporally at 5 minute resolution.

Version 1.2 is intended as a replacement and continuation of the Version 1.1 data forward from orbital revolution number 5127, corresponding to 19 August 2015; the overlapping time period starting on 19 August 2015 corresponds to the first time period of the recorded low signal-to-noise ratio (SNR). This Version 1.2 dataset differs from the previous Version 1.1 dataset as follows: 1) L1B sigma-0 has been re-calibrated during the periods of low signal-to-noise ratio (SNR) and 2) during low SNR periods the L1B sigma-0 calibration is determined using re-pointed L1B QuikSCAT data. Due to the circular scan of the RapidScat instrument the expected number of Sigma-0 cells per WVC is not constant. To minimize the L2A data volume, the Sigma-0 cell data are stored as \"lists\" for each WVC row, with each list indexed by a \"cell_index\" array to indicate the cross-track WVC membership of the data. Each cell is then checked for land or ice and flagged accordingly. Attenuation corrections for each Sigma-0 measurement are also provided. Data are provided in single-orbit files in HDF-4 format. RapidScat is a Ku-band dual beam circular rotating scatterometer retaining much of the same hardware and functionality of QuikSCAT, with exception of the antenna sub-system and digital interface to the International Space Station (ISS) Columbus module, which is where RapidScat is mounted. The NASA mission is officially referred to as ISS-RapidScat. Unlike QuikSCAT, ISS-RapidScat is not in sun-synchronous orbit, and flies at roughly half the altitude with a low inclination angle that restricts data coverage to the tropics and mid-latitude regions; the extent of latitudinal coverage stretches from approximately 61 degrees North to 61 degrees South.

Aqua was launched by NASA on May 4, 2002, into a sun synchronous, polar orbit with a daylight ascending node at 13:30, formation flying in the A-train with other Earth Observation Satellites (EOS), to study the global dynamics of the Earth atmosphere, land and oceans. MODIS captures data in 36 spectral bands at a variety of spatial resolutions. Two SST products can be present in these files. The first is a skin SST produced for both day and night (NSST) observations, derived from the long wave IR 11 and 12 micron wavelength channels, using a modified nonlinear SST algorithm intended to provide continuity of SST derived from heritage and current NASA sensors. At night, a second SST product is generated using the mid-infrared 3.95 and 4.05 micron wavelength channels which are unique to MODIS; the SST derived from these measurements is identified as SST4. The SST4 product has lower uncertainty, but due to sun glint can only be used at night. To generate the L3 products the L2 pixels are binned into an integerized sinusoidal area grid (ISEAG) and mapped into an equidistant cylindrical (also known as Platte Carre projection.

For 'egg' measurements, the full antenna/processing spatial response is used while a simplified spatial response function in which the spatial response is assumed to be 1 over the footprint and 0 elsewhere is used for 'slice' measurements. The SIR algorithm with 'eggs' makes images of sigma-0 at the measurement incidence angle at 4.5 km pixel resolution. The effective resolution varies depending on region and sampling conditions but is estimated to be 8-10 km in most areas. The SIRF algorithm with 'slices' makes images at 2.225 km pixel resolution with an estimated effective resolution of 6-8 km. It is worth noting that 'slice' measurements are inherently noisier than 'egg' measurements. This dataset has been pre-subsetted for the following regions: Alaska, Amazonia, Antarctica, Arctic, Australia, Bering Strait, Greenland, Central America, East China Sea, Sea of Japan, Europe, Indonesia, Northern Africa, North America, Southern Africa, South America, Southern Asia, and Siberia. Non-enhanced fields are also provided at lower resolution in a 'GRD' gridded format that does not utilize SIR processing; 'GRD' fields are provided at 11.125 km and 22.25 km pixel resolution for slices and eggs, respectively. In addition to Sigma-0, various statistical parameters are provided for added guidance, including but not limited to: standard deviation of incidence angle, mean incidence angle, measurement counts, pixel time, mean reconstruction error, and standard deviation of the reconstructed sigma-0. Sigma-0 fields are available for specific ascending/descending nodes, local time of day, or as a daily average. SIR-formatted land mask files (containing 0 for ocean and 1 for land) are available for each standard region.

Aqua was launched by NASA on May 4, 2002, into a sun synchronous, polar orbit with a daylight ascending node at 13:30, formation flying in the A-train with other Earth Observation Satellites (EOS), to study the global dynamics of the Earth atmosphere, land and oceans. MODIS captures data in 36 spectral bands at a variety of spatial resolutions. Two SST products can be present in these files. The first is a skin SST produced for both day and night (NSST) observations, derived from the long wave IR 11 and 12 micron wavelength channels, using a modified nonlinear SST algorithm intended to provide continuity of SST derived from heritage and current NASA sensors. At night, a second SST product is generated using the mid-infrared 3.95 and 4.05 micron wavelength channels which are unique to MODIS; the SST derived from these measurements is identified as SST4. The SST4 product has lower uncertainty, but due to sun glint can only be used at night.

The wind vector retrievals are currently processed using the CMOD7.n geophysical model function using a Hamming filter to spatially average the Sigma-0 data in the ASCAT L1B data. Each file is provided in netCDF version 3 format, and contains one full orbit derived from 3-minute orbit granules. Latency is approximately 2 hours from the latest measurement. The beginning of the orbit is defined by the first wind vector cell measurement within the first 3-minute orbit granule that starts north of the Equator in the ascending node.

The fundamental difference between Version 1.3 and the previous Version 1.2 datasets is that the L1B sigma-0 has been re-calibrated during the periods of low SNR states 3 and 4 using re-pointed QuikSCAT data. The Version 1.1 should still be considered valid up to the first rev of version 1.2 (5127), and similarly version 1.2 shall be considered valid up to the first rev of version 1.3 (7873).

The NASA mission is officially referred to as ISS-RapidScat. Unlike QuikSCAT, ISS-RapidScat is not in sun-synchronous orbit, and flies at roughly half the altitude with a low inclination angle that restricts data coverage to the tropics and mid-latitude regions; the extent of latitudinal coverage stretches from approximately 61 degrees North to 61 degrees South. Furthermore, there is no consistent local time of day retrieval.

The AVHRR is a space-borne scanning sensor on the National Oceanic and Atmospheric Administration (NOAA) family of Polar Orbiting Environmental Satellites (POES) having a operational legacy that traces back to the Television Infrared Observation Satellite-N (TIROS-N) launched in 1978. AVHRR instruments measure the radiance of the Earth in 5 (or 6) relatively wide spectral bands. The first two are centered around the red (0.6 micrometer) and near-infrared (0.9 micrometer) regions, the third one is located around 3.5 micrometer, and the last two sample the emitted thermal radiation, around 11 and 12 micrometers, respectively. The legacy 5 band instrument is known as AVHRR/2 while the more recent version, the AVHRR/3 (first carried on the NOAA-15 platform), acquires data in a 6th channel located at 1.6 micrometer. Typically the 11 and 12 micron channels are used to derive SST sometimes in combination with the 3.5 micron channel. The NOAA platforms are sun synchronous generally viewing the same earth location twice a day (latitude dependent) due to the relatively large AVHRR swath of approximately 2400 km. The highest ground resolution that can be obtained from the current AVHRR instruments is 1.1 km at nadir. AVHRR data are acquired in three formats: High Resolution Picture Transmission (HRPT), Local Area Coverage (LAC), and Global Area Coverage (GAC). HRPT data are full resolution image data transmitted to a ground stations as they are collected. LAC are also full resolution data, but the acquisition is prescheduled and recorded with an on-board tape recorder for subsequent transmission during a station overpass. This particular dataset is produced from GAC data that are derived from an on-board sample averaging of the full resolution global AVHRR data. Four out of every five samples along the scan line are used to compute on average value and the data from only every third scan line are processed, yielding an effective 4 km resolution at nadir. Further binning and averaging of these pixels results in a final dataset resolution of 8.8 km."@en ; "None"@en ; "EARTH SCIENCE"@en ; "2020-09-16"^^xsd:date ; "2006-06-29 E.

Average daily, weekly (8 day), monthly and annual skin SST products are available at both 4.63 and 9.26 km spatial resolution. Terra was launched by NASA on December 18, 1999, into a sun synchronous, polar orbit with a daylight descending node at 10:30 am, to study the global dynamics of the Earth atmosphere, land and oceans. The MODIS captures data in 36 spectral bands at a variety of spatial resolutions. Two SST products can be present in these files. The first is a skin SST produced for both day and night observations, derived from the long wave IR 11 and 12 micron wavelength channels, using a modified nonlinear SST algorithm intended to provide continuity with SST derived from heritage and current NASA sensors. At night, a second SST product is produced using the mid-infrared 3.95 and 4.05 micron channels which are unique to MODIS; the SST derived from these measurements is identified as SST4. The SST4 product has lower uncertainty, but due to sun glint can only be produced at night. To generate the L3 products the L2 pixels are binned into an integerized sinusoidal area grid (ISEAG) and mapped into an equidistant cylindrical (also known as Platte Carre) projection.

The eight hour interval at each LTOD reference of morning vs. afternoon corresponds to the natural boundaries of time separation within the data at polar latitudes.

Version 1.2 is intended as a replacement and continuation of the Version 1.1 data forward from orbital revolution number 5127, corresponding to 19 August 2015; the overlapping time period starting on 19 August 2015 corresponds to the first time period of the recorded low signal-to-noise ratio (SNR). This Version 1.2 dataset differs from the previous Version 1.1 dataset as follows: 1) L1B sigma-0 has been re-calibrated during the periods of low signal-to-noise ratio (SNR) and 2) during low SNR periods the L1B sigma-0 calibration is determined using re-pointed L1B QuikSCAT data. The pulse \"egg\" represents the complete footprint of the pulse, which has a spatial geometry of approximately 25 km by 35 km. There are 8 slices that constitute the range-binned components of a pulse each of which has a spatial geometry of approximately 25 km by 7 km. The orientation of the long dimension of the slices varies with the rotation of the antenna and thus does not align with the along/across track orientation of the wind vector grid in the L2B/L2A products. Data are provided in single-orbit files in HDF-4 format. RapidScat is a Ku-band dual beam circular rotating scatterometer retaining much of the same hardware and functionality of QuikSCAT, with exception of the antenna sub-system and digital interface to the ISS Columbus module, which is where RapidScat is mounted. The NASA mission is officially referred to as ISS-RapidScat. Unlike QuikSCAT, ISS-RapidScat is not in sun-synchronous orbit, and flies at roughly half the altitude with a low inclination angle that restricts data coverage to the tropics and mid-latitude regions; the extent of latitudinal coverage stretches from approximately 61 degrees North to 61 degrees South. Furthermore, there is no consistent local time of day retrieval. Caution: this dataset is intended for expert use only. If you must use RapidScat Sigma-0 data but you are unsure about how to use the L1B data record, please consider using either of the following L2A datasets: 1) http://podaac.jpl.nasa.gov/dataset/RSCAT_L2A_12KM_V1.2 or 2) http://podaac.jpl.nasa.gov/dataset/RSCAT_L2A_25KM_V1.2.

The project involves two field campaigns and a series of cruises in regions of the Atlantic and Pacific Oceans exhibiting salinity extremes. SPURS employs a suite of state-of-the-art in-situ sampling technologies that, combined with remotely sensed salinity fields from the Aquarius/SAC-D and SMOS satellites, provide a detailed characterization of salinity structure over a continuum of spatio-temporal scales. The SPURS-1 campaign involved a series of 5 cruises during 2012 - 2013 seeking to characterize the salinity structure and balance in a high salinity, high evaporation, and low rainfall region of the subtropical North Atlantic. It aims to resolve processes responsible for maintaining the subtropical surface salinity maximum in this region and within a 900 x 800-mile square study area centered at 25N, 38W. All US SPURS-1 cruises (Knorr: 6 Sept-9 Oct 2012; Endeavor: 15 Mar-15 Apr 2013 and 19 Sep-13 Oct 2013) were equipped with a ship mast meteorological sensor package. An additional set of sophisticated meteorological sensors, including a direct covariance flux package, was installed on the Knorr.

Average daily, weekly (8 day), monthly and annual skin SST products are available at both 4.63 and 9.26 km spatial resolution. Terra was launched by NASA on December 18, 1999, into a sun synchronous, polar orbit with a daylight descending node at 10:30 am, to study the global dynamics of the Earth atmosphere, land and oceans. The MODIS captures data in 36 spectral bands at a variety of spatial resolutions. Two SST products can be present in these files. The first is a skin SST produced for both day and night observations, derived from the long wave IR 11 and 12 micron wavelength channels, using a modified nonlinear SST algorithm intended to provide continuity with SST derived from heritage and current NASA sensors. At night, a second SST product is produced using the mid-infrared 3.95 and 4.05 micron channels which are unique to MODIS; the SST derived from these measurements is identified as SST4. The SST4 product has lower uncertainty, but due to sun glint can only be produced at night. To generate the L3 products the L2 pixels are binned into an integerized sinusoidal area grid (ISEAG) and mapped into an equidistant cylindrical (also known as Platte Carre) projection. Additional projection detailed can be found at https://oceancolor.gsfc.nasa.gov/docs/format/The NASA MODIS L3 SST data products are generated by the NASA Ocean Biology Processing Group (OBPG) Peter Minnett and his team at the Rosenstiel School of Marine and Atmospheric Science (RSMAS) are responsible for sea surface temperature algorithm development, error statistics and quality flagging. JPL acquires and distributes MODIS ocean L3 SST data from the OBPG as the official Physical Oceanography Data Archive (PO.DAAC) for SST.

The SST data in this data set are used operationally in oceanographic analyses and forecasts by the US Naval Oceanographic Office (NAVO). The MetOp satellite program is a European multi-satellite program to provide weather data services for monitoring climate and improving weather forecasts. MetOp-A, MetOp-B and Metop-C were respectively launched on 19 Oct 2006, 17 September 2012 and 7 November 2018. The program was jointly established by the European Space Agency (ESA) and the European Organization for the Exploitation of Meteorological Satellites (EUMETSAT) with the US National Oceanic and Atmospheric Administration (NOAA) contributing the AVHRR sensor. AVHRR instruments measure the radiance of the Earth in 5 (or 6) relatively wide spectral bands. The first two are centered around the red (0.6 micron) and near-infrared (0.9 micron) regions, the third one is located around 4 (3.6) micron, and the last two sample the emitted thermal radiation, around 11 and 12 micron, respectively. The legacy 5 band instrument is known as AVHRR/2 while the more recent version, the AVHRR/3 (first carried on the NOAA-15 platform), acquires data in a 6th channel located at 1.6 micron. Typically, the 11 and 12 micron channels are used to derive SST sometimes in combination with the 3.5 micron channel. The swath of the AVHRR sensor is a relatively large 2400 km. All MetOp platforms are sun synchronous and generally view the same earth location twice a day (latitude dependent). The ground native resolution of the AVHRR instruments is approximately 1.1 km at nadir and degrades off nadir. This particular data set is produced from legacy Global Area Coverage (GAC) data that are derived from a sample averaging of the full resolution global AVHRR data. Four out of every five samples along the scan line are used to compute on average value and the data from only every third scan line are processed, yielding an effective 4 km spatial resolution at nadir. The v2.0 is the updated version from current v1.0 with extensive algorithm improvements and upgrades. The major improvements include: 1) Significant changes in contaminant/cloud detection; 2) Increased the spatial resolution from 9 km to 4 km; 3) Updated compliance with GDS2, ACDD 1.3, and CF 1.6; and 4) Removed the dependency on the High-resolution Infrared Radiation Sounder (HIRS) sensor (only available to MetOp-A/B), thus allowing for the consistent inter-calibration and the processing of MetOp-A/B/C data"@en ; "None"@en ; "EARTH SCIENCE"@en ; "2020-09-16"^^xsd:date ; "Dataset Creation via Metadata Tool"@en ; "https://podaac.jpl.nasa.gov/" ; "English"@en ; "Naval Oceanographic Office"@en ; "Naval Oceanographic Office"@en ; "2020-07-24"^^xsd:date ; "Stennis Space Center, MS, USA"@en ; "GHRSST Level 2P Global 1m Sea Surface Temperature v2.0 from the Advanced Very High Resolution Radiometer (AVHRR) on the MetOp-B satellite produced by NAVO"@en ; "METOP-A AVHRR GAC L2P swath SST dataset"@en ; "180.0"^^xsd:float ; "podaac@podaac.jpl.nasa.gov"@en ; "PODAAC-GHMTB-2PN20" ; "GHRSST Level 2P Global Sea Surface Temperature v2.0 from the AVHRR on the MetOp-B satellite produced by NAVO"@en ; ""@en ; "Oceans"@en , "Geoscientific Information"@en ; "2020-06-11"^^xsd:date ; ""@en ; "0.04"^^xsd:float ; "Geographic Region"@en ; "Global"@en ; ""@en , "Advanced Very High Resolution Radiometer-3"@en , "Meteorological Operational Satellite - B"@en , "Group for High Resolution Sea Surface Temperature"@en ; "0.04"^^xsd:float ; "CEOS IDN DIF"@en ; "9.8"^^xsd:float ; "80.0"^^xsd:float ; "https://podaac.jpl.nasa.gov/GHRSST" ; "DOD/USNAVY/NAVOCEANO"@en ; "Data Center Contact"@en ; "USA/NASA"@en , "AVHRR-3"@en , "METOP-B"@en , ""@en , "GHRSST"@en ; "-70.0"^^xsd:float ; "2020-06-22"^^xsd:date ; "OCEAN TEMPERATURE"@en ; "OCEANS"@en ; "None"@en ; "SEA SURFACE TEMPERATURE"@en ; "2.0"^^xsd:float ; "-180.0"^^xsd:float . a base: ; owl:versionInfo "2020-09-16T19:36:14.452Z" ; "Aquarius Level 3 sea surface density standard mapped image data contains gridded 1 degree spatial resolution density data averaged over daily, 7 day, monthly, and seasonal time scales.

The reported sample locations are determined by the specular points corresponding to the Delay Doppler Maps (DDMs). A subset of DDM data used in the direct processing of the average wind speed and MSS is co-located inside of the Level 2 data files. Only one netCDF data file is produced each day (each file containing data from up to 8 unique CYGNSS spacecraft) with a latency of approximately 6 days (or better) from the last recorded measurement time. The Version 1.0 CDR represents the first climate-quality release and is a collection of reanalysis products derived from the SDR v2.1 Level 1 data. Calibration accuracy and long term stability are improved relative to the SDR v2.1 using a new trackwise correction algorithm which constrains the average value of the L1 data using MERRA-2 reanalysis wind speeds. Details of the algorithm are provided in the Trackwise Corrected CDR Algorithm Theoretical Basis Document. CDR Level 2 and 3 products (ocean surface wind speed, mean square slope, and latent and sensible heat flux) are generated from the CDR L1 data using the v2.1 SDR data processing algorithms. These products also exhibit improved calibration accuracy and stability over SDR v2.1. Trackwise correction is applied to the two primary CYGNSS L1 science data products the normalized bistatic radar cross section (NBRCS) and the leading edge slope of the Doppler-integrated delay waveform (LES). The correction compensates for variations in the transmit power level of the GPS signals measured by the CYGNSS bistatic radar receivers. The SDR v2.1 L1 algorithm assumes a constant GPS transmit power and variations in it can be misinterpreted as variations in the L1 data and in subsequent L2 science data products derived from them. The GPS constellation consists of several different satellite models (a.k.a. block types) and the level of transmit power variation differs between them. The more recent Block IIF models (which account for ~37% of the GPS constellation) have significantly larger variations than the older models and, for this reason, they have been screened out and not used to produce SDR v2.1 L2 or L3 science data products. Trackwise correction eliminates the need for this screening so CDR L2 and L3 data products now include Block IIF samples. It should be noted that the trackwise correction algorithm cannot be successfully applied to all SDR v2.1 L1 data so there is also some loss of samples that were present in SDR v2.1.

Samples using block II-F signals receive a fatal Q/C flag due to the higher level of uncertainty in their radiated power; 6) revised wind speed uncertainty values as a function of RCG and wind speed, plus a new dependence of the uncertainty on GPS block type to reflect the higher uncertainty in GPS radiated power for block II-F satellites."@en ; "NONE"@en ; "EARTH SCIENCE"@en ; "2020-09-16"^^xsd:date ; "Dataset Creation via Metadata Tool"@en ; "https://podaac.jpl.nasa.gov/" ; "English"@en ; "CYGNSS"@en ; "PO.DAAC"@en ; "2018-09-21"^^xsd:date ; "PO.DAAC"@en ; "CYGNSS Level 2 Science Data Record"@en ; "CYGNSS Level 2 Science Data Record Version 2.1"@en ; "360.0"^^xsd:float ; "podaac@podaac.jpl.nasa.gov"@en ; "PODAAC-CYGNS-L2X21" ; "CYGNSS Level 2 Science Data Record Version 2.1"@en ; ""@en ; "Oceans"@en , "Geoscientific Information"@en ; "2018-05-14"^^xsd:date ; ""@en ; "Geographic Region"@en ; "Global"@en ; "Delay Doppler Mapping Instrument"@en , ""@en , "Cyclone Global Navigation Satellite System"@en ; "CEOS IDN DIF"@en ; "9.8"^^xsd:float ; "40.0"^^xsd:float ; "http://clasp-research.engin.umich.edu/missions/cygnss/" ; "NASA/ESSP/UMICH/CYGNSS"@en ; "Data Center Contact"@en ; ""@en , "DDMI"@en , "USA/NASA"@en , "CYGNSS"@en ; "40.0"^^xsd:float ; "2017-03-18"^^xsd:date ; "RADAR"@en , "OCEAN WINDS"@en ; "SPECTRAL/ENGINEERING"@en , "OCEANS"@en ; "NONE"@en ; "RADAR CROSS-SECTION"@en , "SURFACE WINDS"@en ; "2.1"^^xsd:float ; "0.0"^^xsd:float . a owl:DatatypeProperty . a base: ; owl:versionInfo "2020-09-16T19:36:14.439Z" ; "A Group for HIgh Resolution Sea Surface Temperature (GHRSST) dataset for the North Atlantic Region (NAR) from the Advanced Very High Resolution Radiometer (AVHRR) on the NOAA-19 platform (launched 6 Feb 2009). This particular dataset is produced by the European Organization for the Exploitation of Meteorological Satellites (EUMETSAT), Ocean and Sea Ice Satellite Application Facility (OSI SAF) in France. The AVHRR is a space-borne scanning sensor on the National Oceanic and Atmospheric Administration (NOAA) family of Polar Orbiting Environmental Satellites (POES) having a operational legacy that traces back to the Television Infrared Observation Satellite-N (TIROS-N) launched in 1978. AVHRR instruments measure the radiance of the Earth in 5 (or 6) relatively wide spectral bands. The first two are centered around the red (0.6 micrometer) and near-infrared (0.9 micrometer) regions, the third one is located around 3.5 micrometer, and the last two sample the emitted thermal radiation, around 11 and 12 micrometers, respectively. The legacy 5 band instrument is known as AVHRR/2 while the more recent version, the AVHRR/3 (first carried on the NOAA-15 platform), acquires data in a 6th channel located at 1.6 micrometer. Typically the 11 and 12 micron channels are used to derive sea surface temperature (SST) sometimes in combination with the 3.5 micron channel. The highest ground resolution that can be obtained from the current AVHRR instruments is 1.1 km at nadir. The MetOp-A platform is sun synchronous generally viewing the same earth location twice a day (latitude dependent) due to the relatively large AVHRR swath of approximately 2400 km. The NAR products are SST fields derived from 1km AVHRR data that are re-mapped onto a 0.02 degree equal angle grid. In the processing chain, global AVHRR level 1b data are acquired at Centre de Meteorologie Spatiale (CMS) through the EUMETSAT/EUMETCAST system. A cloud mask is applied and SST is retrieved from the AVHRR infrared (IR) channels by using a multispectral technique.

The AVHRR is a space-borne scanning sensor on the National Oceanic and Atmospheric Administration (NOAA) family of Polar Orbiting Environmental Satellites (POES) having a operational legacy that traces back to the Television Infrared Observation Satellite-N (TIROS-N) launched in 1978. AVHRR instruments measure the radiance of the Earth in 5 (or 6) relatively wide spectral bands. The first two are centered around the red (0.6 micrometer) and near-infrared (0.9 micrometer) regions, the third one is located around 3.5 micrometer, and the last two sample the emitted thermal radiation, around 11 and 12 micrometers, respectively. The legacy 5 band instrument is known as AVHRR/2 while the more recent version, the AVHRR/3 (first carried on the NOAA-15 platform), acquires data in a 6th channel located at 1.6 micrometer. Typically the 11 and 12 micron channels are used to derive SST sometimes in combination with the 3.5 micron channel. The NOAA platforms are sun synchronous generally viewing the same earth location twice a day (latitude dependent) due to the relatively large AVHRR swath of approximately 2400 km. The highest ground resolution that can be obtained from the current AVHRR instruments is 1.1 km at nadir. AVHRR data are acquired in three formats: High Resolution Picture Transmission (HRPT), Local Area Coverage (LAC), and Global Area Coverage (GAC). HRPT data are full resolution image data transmitted to a ground stations as they are collected. LAC are also full resolution data, but the acquisition is prescheduled and recorded with an on-board tape recorder for subsequent transmission during a station overpass. GAC data provide daily subsampled global coverage recorded on tape recorders and then transmitted to a ground station. This particular dataset is derived from LAC data. Further binning and averaging of the 1.1 km LAC pixels results in a final dataset resolution of 2.2 km. The coverage of the LAC data can vary but generally contains scenes over the oceans adjacent to Australia and the North Indian Ocean."@en ; "None"@en ; "EARTH SCIENCE"@en ; "2020-09-16"^^xsd:date ; "Dataset Creation via Metadata Tool"@en ; "https://podaac.jpl.nasa.gov/" ; "English"@en ; "Naval Oceanographic Office"@en ; "Naval Oceanographic Office"@en ; "2014-10-27"^^xsd:date ; "Stennis Space Center, MS, USA"@en ; "GHRSST Level 2P Regional 1m Sea Surface Temperature from the Advanced Very High Resolution Radiometer (AVHRR) on the NOAA-19 satellite produced by NAVO"@en ; "N-19 AVHRR LAC L2P swath SST data set"@en ; "180.0"^^xsd:float ; "podaac@podaac.jpl.nasa.gov"@en ; "PODAAC-GH19L-2PN02" ; "GHRSST Level 2P Regional 1m Sea Surface Temperature from the Advanced Very High Resolution Radiometer (AVHRR) on the NOAA-19 satellite produced by NAVO"@en ; ""@en ; "Oceans"@en , "Geoscientific Information"@en ; "2017-04-28"^^xsd:date ; ""@en ; "Geographic Region"@en ; "Global"@en ; "National Oceanic & Atmospheric Administration-19"@en , "Advanced Very High Resolution Radiometer"@en , "Group for High Resolution Sea Surface Temperature"@en , ""@en ; "CEOS IDN DIF"@en ; "9.8"^^xsd:float ; "80.0"^^xsd:float ; "" ; "Naval Oceanographic Office"@en ; "Data Center Contact"@en ; "AVHRR"@en , "USA/NASA"@en , "NOAA-19"@en , ""@en , "GHRSST"@en ; "-70.0"^^xsd:float ; "2013-05-05"^^xsd:date ; "OCEAN TEMPERATURE"@en ; "OCEANS"@en ; "None"@en ; "SEA SURFACE TEMPERATURE"@en ; "1.0"^^xsd:float ; "-180.0"^^xsd:float . a base: ; owl:versionInfo "2020-09-16T19:36:14.562Z" , "2020-09-16T19:36:14.601Z" ; "Day and night spatially gridded (L3) global NASA skin sea surface temperature (SST) products from the Moderate-resolution Imaging Spectroradiometer (MODIS) onboard the Aqua satellite.

The satellite altimetric record provides accurate measurements of sea level with near-global coverage, but it has a relatively short time span, since 1993. Tide gauges have measured sea level over the last 200 years, with some records extending back to 1807, but they only provide regional coverage, not global. Combining satellite altimetry with tide gauges, using a technique known as sea level reconstruction, results in a dataset with the record length of the tide gauges and the near-global coverage of satellite altimetry. Cyclostationary empirical orthogonal functions (CSEOFs), derived from satellite altimetry, are combined with historical sea level measurements from tide gauges to create the Reconstructed Sea Level dataset spanning from 1950 through 2009. Combining the altimetric and tide gauge records alleviates the difficulties caused by the short record length and poor spatial distribution of the satellite altimetry and tide gauges, respectively.

CAP is a P.I. produced dataset developed and provided by JPL. This Level 2 dataset contains sea surface salinity (SSS), wind speed and wind direction data derived from 3 different radiometers and the onboard scatterometer. The CAP algorithm simultaneously retrieves the salinity, wind speed and direction by minimizing the sum of squared differences between model and observations. The main improvements in CAP V5.0 relative to the previous version include: updates to the Geophysical Model Functions to 4th order harmonics with the inclusion of sea surface temperature (SST) and stability at air-sea interface effects; use of the Canadian Meteorological Center (CMC) SST product as the new source ancillary sea surface temperature data in place of NOAA OI SST. Each L2 data file covers one 98 minute orbit. The Aquarius instrument is onboard the AQUARIUS/SAC-D satellite, a collaborative effort between NASA and the Argentinian Space Agency Comision Nacional de Actividades Espaciales (CONAE).

The project involves two field campaigns and a series of cruises in regions of the Atlantic and Pacific Oceans exhibiting salinity extremes. SPURS employs a suite of state-of-the-art in-situ sampling technologies that, combined with remotely sensed salinity fields from the Aquarius/SAC-D, SMAP and SMOS satellites, provide a detailed characterization of salinity structure over a continuum of spatio-temporal scales. The SPURS-2 campaign involved two month-long cruises by the R/V Revelle in August 2016 and October 2017 combined with complementary sampling on a more continuous basis over this period by the schooner Lady Amber. Focused around a central mooring located near 10N,125W, the objective of SPURS-2 was to study the dynamics of the rainfall-dominated surface ocean at the western edge of the eastern Pacific fresh pool subject to high seasonal variability and strong zonal flows associated with the North Equatorial Current and Countercurrent. A Rawinsonde is a helium balloon carrying meteorological instruments and a radar target, enabling the velocity of atmospheric parameters to be measured. During the first Revelle cruise, rawinsondes were launched every 6-hours, providing a total of 85 profiles of temperature, humidity, wind speed and direction through the marine atmospheric boundary layer within the SPURS-2 domain. Similarly, during the second Revelle cruise, rawinsondes were deployed four-times daily within the study area over the 3-week period.

Incidence angles were varied in order to cross-calibrate the Oceansat-2 and RapidScat scatterometers and to extend the known Ku-band geophysical model function. The averaging of the L1B input data combined with the wind vector processing results are both contained in this product referred to hereafter as Level 1C (L1C). The fixed and repointed beam processing is relative to either the one corresponding to the vertically polarized \"outer\" beam or the other corresponding to the horizontally polarized \"inner\" beam. The Sigma-0 values from the fixed operating beam for each frame are averaged to a single value representing approximately 50 samples. The data points are land flagged, collocated with ECMWF surface winds, and have climatological nadir attenuations provided for the location and time of the data (not applied to the sigma0). For orbits prior to 87727 the RapidSCAT geophysical model function (GMF) has been used to compute wind speed and direction, which is provided at each discrete sampling point corresponding to the averaged Sigma-0 locations. From orbit 87727 to present, a newer GMF designed specifically to determine wind speed from QuikSCAT backscatter and ECMWF wind direction was employed. The wind speed were computed from QuikSCAT Sigma0 values by assuming the ECMWF wind direction as a first step and then refining those directions slightly to minimize differences between ECMWF and QuikSCAT wind vectors. Retrieved wind directions, thus obtained, were reported but are only slightly different from ECMWF values and should not be considered an independent measurement of wind direction. Retrieved wind speeds do not depend significantly on ECMWF speeds as evidenced by the fact that they agree closely with WindSAT polarimetric radiometer speeds whenever WindSAT and ECMWF disagree. The Sigma0 values have also been corrected for scan loss (due to the fact that the antenna does not scan) and for X-factor changes due to repointing.

MTSAT carries an aeronautical mission to assist air navigation, plus a meteorological mission to provide imagery over the Asia-Pacific region for the hemisphere centered on 140 East. The meteorological mission includes an imager giving nominal hourly full Earth disk images in five spectral bands (one visible, four infrared). MTSAT are spin stabilized satellites. With this system images are built up by scanning with a mirror that is tilted in small successive steps from the north pole to south pole at a rate such that on each rotation of the satellite an adjacent strip of the Earth is scanned. It takes about 25 minutes to scan the full Earth's disk. This builds a picture 10,000 pixels for the visible images (1.25 km resolution) and 2,500 pixels (4 km resolution) for the infrared images. The MTSAT-2 (also known as Himawari 7) and its radiometer (MTSAT-2 Imager) was successfully launched on 18 February 2006. For this Group for High Resolution Sea Surface Temperature (GHRSST) dataset, skin sea surface temperature (SST) measurements are calculated from the IR channels of the MTSAT-2 Imager full resolution data in satellite projection on a hourly basis by using Bayesian Cloud Mask algorithm at the Office of Satellite and Product Operations (OSPO).

The SPURS-1 campaign involved a series of 5 cruises during 2012 - 2013 seeking to characterize the salinity structure and balance in a high salinity, high evaporation, and low rainfall region of the subtropical North Atlantic. It aims to resolve processes responsible for maintaining the subtropical surface salinity maximum in this region and within a 900 x 800-mile square study area centered at 25N, 38W.

The RL03 SCA1B data were corrected for a stellar aberration error in the onboard star tracker software and incorrect data weighting in the star tracker combination software. For the RL03 SCA1B data a new software module was developed that uses Kalman filtering, field of view error modeling, relative alignment adjustment and the inclusion of angular spacecraft body acceleration measurements from the ACC instrument. This new processing resulted in a significant reduction in high frequency noise and the elimination of jumps during transitions between dual and single star tracker operation.

N20 was launched on November 18, 2017. In conjunction with the first US satellite in JPSS series, Suomi National Polar-orbiting Partnership (S-NPP) satellite launched on October 28, 2011, N20 form the new NOAA polar constellation. NOAA is responsible for all JPSS products, including SST from the Visible Infrared Imaging Radiometer Suite (VIIRS). VIIRS is a whiskbroom scanning radiometer, which takes measurements in the cross-track direction within a field of view of 112.56-deg using 16 detectors and a double-sided mirror assembly. At a nominal altitude of 829 km, the swath width is 3,060 km, providing global daily coverage for both day and night passes. VIIRS has 22 spectral bands, covering the spectrum from 0.4-12 um, including 16 moderate resolution bands (M-bands). The L2P SST product is derived at the native sensor resolution (~0.75 km at nadir, ~1.5 km at swath edge) using NOAA's Advanced Clear-Sky Processor for Ocean (ACSPO) system, and reported in 10 minute granules in netCDF4 format, compliant with the GHRSST Data Specification version 2 (GDS2). There are 144 granules per 24hr interval, with a total data volume of 27GB/day. In addition to pixel-level earth locations, Sun-sensor geometry, and ancillary data from the NCEP global weather forecast, ACSPO outputs include four brightness temperatures (BTs) in M12 (3.7um), M14 (8.6um), M15 (11um), and M16 (12um) bands, and two reflectances in M5 (0.67um) and M7 (0.87um) bands. The reflectances are used for cloud identification. Beginning with ACSPO v2.60, all BTs and reflectances are destriped (Bouali and Ignatov, 2014) and resampled (Gladkova et al., 2016), to minimize the effect of bow-tie distortions and deletions. SSTs are retrieved from destriped BTs. SSTs are derived from BTs using the Multi-Channel SST (MCSST; night) and Non-Linear SST (NLSST; day) algorithms (Petrenko et al., 2014). ACSPO clear-sky mask (ACSM) is provided in each pixel as part of variable l2p_flags, which also includes day/night, land, ice, twilight, and glint flags (Petrenko et al., 2010). Fill values are reported in all pixels with >5 km inland. For each valid water pixel (defined as ocean, sea, lake or river, and up to 5 km inland), four BTs in M12/14/15/16 (included for those users interested in direct \"radiance assimilation\", e.g., NOAA NCEP, NASA GMAO, ECMWF) and two refelctances in M5/7 are reported, along with derived SST. Other variables include NCEP wind speed and ACSPO SST minus reference SST (Canadian Met Centre 0.1deg L4 SST; available at https://podaac.jpl.nasa.gov/dataset/CMC0.1deg-CMC-L4-GLOB-v3.0). Only ACSM confidently clear pixels are recommended (equivalent to GDS2 quality level=5). Per GDS2 specifications, two additional Sensor-Specific Error Statistics layers (SSES bias and standard deviation) are reported in each pixel with QL=5. Note that users of ACSPO data have the flexibility to ignore the ACSM and derive their own clear-sky mask, and apply it to BTs and SSTs. They may also ignore ACSPO SSTs, and derive their own SSTs from the original BTs.

The CCMP datasets combine cross-calibrated satellite winds obtained from Remote Sensing Systems (REMSS) using a Variational Analysis Method (VAM) to produce a high-resolution (0.25 degree) gridded analysis. Wind directions from the resulting analysis are assigned to the location and time of the satellite-derived wind speed observations to create this value added dataset. The CCMP data set includes cross-calibrated satellite winds derived from SSM/I, SSMIS, AMSR-E, TRMM TMI, QuikSCAT, SeaWinds, WindSat and other satellite instruments as they become available from REMSS. REMSS uses a cross-calibrated sea-surface emissivity model function which improves the consistency between wind speed retrievals from microwave radiometers (i.e., SSM/I, SSMIS, AMSR, TMI, WindSat) and those from scatterometers (i.e., QuikSCAT and SeaWinds). The VAM combines these data with in situ measurements and a starting estimate (first guess) of the wind field. The European Center for Medium-Range Weather Forecasts (ECMWF) ERA-40 Reanalysis is used as the first-guess from 1987 to 1998. The ECMWF Operational analysis is used from January 1999 onward. All wind observations and analysis fields are referenced to a height of 10 meters. The ERA-40 can be obtained from the Computation and Information Systems Laboratory (CISL) at the National Center for Atmospheric Research (NCAR): http://rda.ucar.edu/datasets/ds117.0/. The ECMWF Operational analysis can also be obtained from CISL at NCAR: http://rda.ucar.edu/datasets/ds111.1/. Three products are distributed to complete the CCMP dataset series. L3.0 product contains high-resolution analyses every 6-hours. These data are then time averaged over monthly and 5-day periods to derive the L3.5 product. Directions from the L3.0 product are then assigned to the time and location of the passive microwave satellite wind speed observations to derive the L2.5 product. All datasets are distributed on a 0.25 degree cylindrical coordinate grid. This dataset is one in a series of First-Look (FLK) CCMP datasets and is a continuation and expansion of the SSM/I surface wind velocity project that began under the NASA Pathfinder Program. Refinements and upgrades to the FLK version will be incorporated under a new release (date to be determined) known as Late-look (LLK) and may include additional satellite datasets. All satellite surface wind data are obtained from REMSS under the DISCOVER project: Distributed Information Services: Climate/Ocean Products and Visualizations for Earth Research (http://www.discover-earth.org/index.html). The CCMP project is the result of an investigation funded by the NASA Making Earth Science data records for Use in Research Environments (MEaSUREs) program (http://community.eosdis.nasa.gov/measures/). In accordance with the MEaSUREs program, the CCMP datasets are also known as Earth System Data Records (ESDRs). In collaboration with private and government institutions, a team led by Dr. Robert Atlas (PI; proposal originally solicited by REASoN, and currently funded by MEaSURES) has created the CCMP project to provide multi-instrument ocean surface wind velocity ESDRs, with wide ranging research applications in meteorology and oceanography."@en ; "NONE"@en ; "EARTH SCIENCE"@en ; "2020-09-16"^^xsd:date ; "Dataset Creation"@en ; "https://podaac.jpl.nasa.gov/" ; "English"@en ; "NASA/GSFC/NOAA"@en ; "PO.DAAC"@en ; "2009-05-08"^^xsd:date ; "PO.DAAC"@en ; "Cross-Calibrated Multi-Platform Ocean Surface Wind Vector L2.5 First-Look SSM/I-F14 Microwave Analyses"@en ; "Cross-Calibrated Multi-Platform Ocean Surface Wind Vector L2.5 First-Look SSM/I-F14 Microwave Analyses"@en ; "360.0"^^xsd:float ; "podaac@podaac.jpl.nasa.gov"@en ; "PODAAC-CCF25-01F14" ; "Cross-Calibrated Multi-Platform Ocean Surface Wind Vector L2.5 First-Look SSM/I-F14 Microwave Analyses"@en ; ""@en ; "Oceans"@en , "Geoscientific Information"@en ; "2011-01-21"^^xsd:date ; ""@en ; "0.25"^^xsd:float ; "Geographic Region"@en ; "Global"@en ; "Defense Meteorological Satellite Program-F14"@en , ""@en , "Making Earth Science Data Records for Use in Research Environments"@en , "Special Sensor Microwave Imager"@en ; "0.25"^^xsd:float ; "CEOS IDN DIF"@en ; "9.8"^^xsd:float ; "89.875"^^xsd:float ; "https://podaac-tools.jpl.nasa.gov/drive/files/allData/ccmp/L2.5/docs/ccmp_users_guide.pdf" ; "NASA/GSFC/NOAA"@en ; "Data Center Contact"@en ; "DMSP 5D-2/F14"@en , "SSM/I"@en , "USA/NASA"@en , ""@en , "MEaSUREs"@en ; "-89.875"^^xsd:float ; "1997-05-07"^^xsd:date ; "2008-08-08"^^xsd:date ; "12 Hour"@en ; "OCEAN WINDS"@en ; "OCEANS"@en ; "NONE"@en ; "SURFACE WINDS"@en ; "1.0"^^xsd:float ; "0.0"^^xsd:float . a base: ; owl:versionInfo "2020-09-16T19:36:14.491Z" ; "Aquarius Level 3 sea surface salinity (SSS) standard mapped image data contains gridded 1 degree spatial resolution SSS averaged over daily, 7 day, monthly, and seasonal time scales.This particular data set is the Annual sea surface salinity product for version 5.0 of the Aquarius data set, which is the official end of mission public data release from the AQUARIUS/SAC-D mission.

It is a product of the European Organization for the Exploitation of Meteorological Satellites (EUMETSAT) Ocean and Sea Ice Satellite Application Facility (OSI SAF) provided through the Royal Netherlands Meteorological Institute (KNMI). This coastal dataset differs from the standard 12.5 and 25 km datasets in that it utilizes a spatial box filter (rather than the Hamming filter) to generate a spatial average of the Sigma-0 retrievals from the Level 1B dataset; all full resolution Sigma-0 retrievals within a 15 km radius of the wind vector cell centroid are used in the averaging. Since the full resolution L1B Sigma-0 retrievals are used, all non-sea retrievals are discarded prior to the Sigma-0 averaging. Each box average Sigma-0 is then used to compute the wind vector cell using the same CMOD5.n geophysical model function as in the standard OSI SAF ASCAT wind vector datasets. With this enhanced coastal retrieval, winds can be computed as close to ~15 km from the coast, as compared to the static ~35 km land mask in the standard 12.5 km dataset. Each file is provided in netCDF version 3 format, and contains one full orbit derived from 3-minute orbit granules. Latency is approximately 2 hours from the latest measurement. The beginning of the orbit is defined by the first wind vector cell measurement within the first 3-minute orbit granule that starts north of the Equator in the ascending node. ASCAT is a C-band dual swath fan beam radar scatterometer providing two independent swaths of backscatter retrievals in sun-synchronous polar orbit aboard the MetOp-B platform.

The project is comprised of two field campaigns and a series of cruises in regions of the Atlantic and Pacific Oceans exhibiting salinity extremes. SPURS employs a suite of state-of-the-art in-situ sampling technologies that, combined with remotely sensed salinity fields from the Aquarius/SAC-D, SMAP and SMOS satellites, provide a detailed characterization of salinity structure over a continuum of spatio-temporal scales. The SPURS-2 campaign involved two month-long cruises by the R/V Revelle in August 2016 and October 2017 combined with complementary sampling on a more continuous basis over this period by the schooner Lady Amber. Focused around a central mooring located near 10N,125W, the objective of SPURS-2 was to study the dynamics of the rainfall-dominated surface ocean at the western edge of the eastern Pacific fresh pool subject to high seasonal variability and strong zonal flows associated with the North Equatorial Current and Countercurrent.

The GCOM-W mission aims to establish the global and long-term observation system to collect data, which is needed to understand mechanisms of climate and water cycle variations, and demonstrate its utilization. AMSR2 onboard the first generation of the GCOM-W satellite will continue Aqua/AMSR-E observations of water vapor, cloud liquid water, precipitation, SST, sea surface wind speed, sea ice concentration, snow depth, and soil moisture. AMSR2 is a remote sensing instrument for measuring weak microwave emission from the surface and the atmosphere of the Earth. From about 700 km above the Earth, AMSR2 will provide us highly accurate measurements of the intensity of microwave emission and scattering. The antenna of AMSR2 rotates once per 1.5 seconds and obtains data over a 1450 km swath. This conical scan mechanism enables AMSR2 to acquire a set of daytime and nighttime data with more than 99% coverage of the Earth every 2 days. Remote Sensing Systems (RSS, or REMSS), providers of these SST data for the Group for High Resolution Sea Surface Temperature (GHRSST) Project, performs a detailed processing of AMSR2 instrument data in two stages. The first stage produces a near-real-time (NRT) product (identified by \"_rt_\" within the file name) which is made as available as soon as possible. This is generally within 3 hours of when the data are recorded. Although suitable for many timely uses the NRT products are not intended to be archive quality. \"Final\" data (currently identified by \"v7.2\" within the file name) are processed when RSS receives the atmospheric model National Center for Environmental Prediction (NCEP) Final Analysis (FNL) Operational Global Analysis.

This dataset contains estimates of geopotential field derived from the Gravity Recovery and Climate Experiment (GRACE) mission measurements and a non-tidal oceanic model produced by the Jet Propulsion Laboratory (JPL). The data are in spherical harmonics averaged over approximately a month. The primary objective of the GRACE mission is to obtain accurate estimates of the mean and time-variable components of the gravity field variations. This objective is achieved by making continuous measurements of the change in distance between twin spacecraft, co-orbiting in about 500 km altitude, near circular, polar orbit, spaced approximately 200 km apart, using a microwave ranging system. In addition to these range change, the non-gravitional forces are measured on each satellite using a high accuracy electrostatic, room-temperature accelerometer. The satellite orientation and position (and timing) are precisely measured using twin star cameras and a GPS receiver, respectively. Spatial and temporal variations in the gravity field affect the orbits (or trajectories) of the twin spacecraft differently. These differences are manifested as changes in the distance between the spacecraft, as they orbit the Earth. This change in distance is reflected in the time-of-flight of microwave signals transmitted and received nearly simultaneously between the two spacecraft. The change in this time of fight is continuously measured by tracking the phase of the microwave carrier signals. The so called dual-one-way range change measurements can be reconstructed from these phase measurements. This range change (or its numerically derived derivatives), along with other mission and ancillary data, is subsequently analyzed to extract the parameters of an Earth gravity field model."@en ; "none"@en ; "EARTH SCIENCE"@en ; "2020-09-16"^^xsd:date ; "Dataset Creation via Metadata Tool"@en ; "https://podaac.jpl.nasa.gov/" ; "English"@en ; "GRACE"@en ; "JPL"@en ; "2018-07-05"^^xsd:date ; "JPL PO.DAAC"@en ; "GRACE Non-Tidal Ocean Geopotential Coefficients JPL (GAB)"@en ; "GRACE_GAB_L2_GRAV_JPL_RL06"@en ; "180.0"^^xsd:float ; "podaac@podaac.jpl.nasa.gov"@en ; "PODAAC-GRGAB-20J06" ; "GRACE NON-TIDAL OCEAN GEOPOTENTIAL COEFFICIENTS JPL RELEASE 6.0 GAB"@en ; ""@en ; "Oceans"@en , "Geoscientific Information"@en ; "2018-06-11"^^xsd:date ; ""@en ; "Geographic Region"@en ; "Global"@en ; ""@en , "GRACE K-Band Ranging System"@en , "Star Camera Assembly"@en , "Gravity Recovery and Climate Experiment"@en , "GRACE SuperSTAR Accelerometer"@en ; "CEOS IDN DIF"@en ; "9.8"^^xsd:float ; "88.0"^^xsd:float ; "https://podaac-tools.jpl.nasa.gov/drive/files/allData/grace/docs/" ; "GRACE/JPL"@en ; "Data Center Contact"@en ; "GRACE KBR"@en , ""@en , "USA/NASA"@en , "GRACE"@en , "GRACE SCA"@en , "GRACE ACC"@en ; "-88.0"^^xsd:float ; "2002-04-04"^^xsd:date ; "2017-06-30"^^xsd:date ; "GRAVITY/GRAVITATIONAL FIELD"@en , "OCEAN PRESSURE"@en ; "SOLID EARTH"@en , "OCEANS"@en ; "none"@en ; "WATER PRESSURE"@en , "GRAVITY"@en ; "6.0"^^xsd:float ; "-180.0"^^xsd:float . a base: ; owl:versionInfo "2020-09-16T19:36:14.500Z" ; "Aquarius Level 3 sea surface salinity (SSS) rain-flagged standard mapped image data contains gridded 1 degree spatial resolution SSS averaged overdaily, 7 day, monthly, and seasonal time scales.

The pulse \"egg\" represents the complete footprint of the pulse, which has a spatial geometry of approximately 25 km by 35 km. There are 8 slices that constitute the range-binned components of a pulse each of which has a spatial geometry of approximately 25 km by 7 km. The orientation of the long dimension of the slices varies with the rotation of the antenna and thus does not align with the along/across track orientation of the wind vector grid in the L2B/L2A products. Data are provided in single-orbit files in HDF-4 format. RapidScat is a Ku-band dual beam circular rotating scatterometer retaining much of the same hardware and functionality of QuikSCAT, with exception of the antenna sub-system and digital interface to the International Space Station (ISS) Columbus module, which is where RapidScat is mounted. The NASA mission is officially referred to as ISS-RapidScat. Unlike QuikSCAT, ISS-RapidScat is not in sun-synchronous orbit, and flies at roughly half the altitude with a low inclination angle that restricts data coverage to the tropics and mid-latitude regions; the extent of latitudinal coverage stretches from approximately 61 degrees North to 61 degrees South. Furthermore, there is no consistent local time of day retrieval. Caution: this dataset is intended for expert use only.

Average daily, weekly (8 day), monthly and annual skin SST products are available at both 4.63 and 9.26 km spatial resolution. Terra was launched by NASA on December 18, 1999, into a sun synchronous, polar orbit with a daylight descending node at 10:30 am, to study the global dynamics of the Earth atmosphere, land and oceans. The MODIS captures data in 36 spectral bands at a variety of spatial resolutions. Two SST products can be present in these files. The first is a skin SST produced for both day and night observations, derived from the long wave IR 11 and 12 micron wavelength channels, using a modified nonlinear SST algorithm intended to provide continuity with SST derived from heritage and current NASA sensors. At night, a second SST product is produced using the mid-infrared 3.95 and 4.05 micron channels which are unique to MODIS; the SST derived from these measurements is identified as SST4. The SST4 product has lower uncertainty, but due to sun glint can only be produced at night. To generate the L3 products the L2 pixels are binned into an integerized sinusoidal area grid (ISEAG) and mapped into an equidistant cylindrical (also known as Platte Carre) projection. Additional projection detailed can be found at https://oceancolor.gsfc.nasa.gov/docs/format/The NASA MODIS L3 SST data products are generated by the NASA Ocean Biology Processing Group (OBPG) Peter Minnett and his team at the Rosenstiel School of Marine and Atmospheric Science (RSMAS) are responsible for sea surface temperature algorithm development, error statistics and quality flagging. JPL acquires and distributes MODIS ocean L3 SST data from the OBPG as the official Physical Oceanography Data Archive (PO.DAAC) for SST.

This QuikSCAT Level 2B dataset contains science-quality ocean surface wind vector retrievals from the NASA SeaWinds scatterometer. The Version 2 L2B data continues to be openly distributed to allow sufficient time for community acceptance of the Version 3 dataset. The retrievals are provided on a non-uniform grid within the swath at 12.5 km pixel resolution. Higher resolution is achieved through a slice composite technique in which high resolution slice measurements from L1B data are composited into a 12.5 km wind vector cell. The increased sampling resolution enables users to obtain wind vectors 10 km closer to shore when compared to the 25 km L2B dataset. Each L2B file corresponds to a specific orbital revolution (rev) number, which begins at the southernmost point of the ascending orbit. An ASCII inline quality report (Q2B) has been generated for each L2B file; each Q2B file provides statistics of various quality elements pertaining to the processing of a specific L2B file. These wind vector retrievals have been processed using the QSCAT-1 geophysical model function. This is the official dataset produced by the QuikSCAT Project through the SeaWinds Processing and Analysis Center (SeaPAC). The SeaWinds instrument is a conical scanning pencil-beam radar, with dual-beam and dual-polarization capability, operating at Ku-band to provide all-weather ocean surface wind vector retrievals.

This particular dataset is produced by the European Organization for the Exploitation of Meteorological Satellites (EUMETSAT), Ocean and Sea Ice Satellite Application Facility (OSI SAF) in France. The AVHRR is a space-borne scanning sensor on the National Oceanic and Atmospheric Administration (NOAA) family of Polar Orbiting Environmental Satellites (POES) having a operational legacy that traces back to the Television Infrared Observation Satellite-N (TIROS-N) launched in 1978. AVHRR instruments measure the radiance of the Earth in 5 (or 6) relatively wide spectral bands. The first two are centered around the red (0.6 micrometer) and near-infrared (0.9 micrometer) regions, the third one is located around 3.5 micrometer, and the last two sample the emitted thermal radiation, around 11 and 12 micrometers, respectively. The legacy 5 band instrument is known as AVHRR/2 while the more recent version, the AVHRR/3 (first carried on the NOAA-15 platform), acquires data in a 6th channel located at 1.6 micrometer. Typically the 11 and 12 micron channels are used to derive sea surface temperature (SST) sometimes in combination with the 3.5 micron channel. The highest ground resolution that can be obtained from the current AVHRR instruments is 1.1 km at nadir. The NOAA-19 platform is sun synchronous generally viewing the same earth location twice a day (latitude dependent) due to the relatively large AVHRR swath of approximately 2400 km. The NAR products are SST fields derived from 1km AVHRR data that are re-mapped onto a 0.02 degree equal angle grid. In the processing chain, global AVHRR level 1b data are acquired at Centre de Meteorologie Spatiale (CMS) through the EUMETSAT/EUMETCAST system. A cloud mask is applied and SST is retrieved from the AVHRR infrared (IR) channels by using a multispectral technique.

This dataset contains estimates of geopotential field derived from the Gravity Recovery and Climate Experiment (GRACE) mission measurements and a non-tidal oceanic and atmospheric model produced by the German Research Centre for Geosciences (GFZ). The data are in spherical harmonics averaged over approximately a month. The primary objective of the GRACE mission is to obtain accurate estimates of the mean and time-variable components of the gravity field variations. This objective is achieved by making continuous measurements of the change in distance between twin spacecraft, co-orbiting in about 500 km altitude, near circular, polar orbit, spaced approximately 200 km apart, using a microwave ranging system. In addition to these range change, the non-gravitional forces are measured on each satellite using a high accuracy electrostatic, room-temperature accelerometer. The satellite orientation and position (and timing) are precisely measured using twin star cameras and a GPS receiver, respectively. Spatial and temporal variations in the gravity field affect the orbits (or trajectories) of the twin spacecraft differently. These differences are manifested as changes in the distance between the spacecraft, as they orbit the Earth. This change in distance is reflected in the time-of-flight of microwave signals transmitted and received nearly simultaneously between the two spacecraft. The change in this time of fight is continuously measured by tracking the phase of the microwave carrier signals. The so called dual-one-way range change measurements can be reconstructed from these phase measurements. This range change (or its numerically derived derivatives), along with other mission and ancillary data, is subsequently analyzed to extract the parameters of an Earth gravity field model."@en ; "none"@en ; "EARTH SCIENCE"@en ; "2020-09-16"^^xsd:date ; "Dataset Creation via Metadata Tool"@en ; "https://podaac.jpl.nasa.gov/" ; "English"@en ; "GRACE"@en ; "GFZ"@en ; "2018-08-31"^^xsd:date ; "JPL PO.DAAC"@en ; "GRACE NON-TIDAL ATMOSPHERE AND OCEAN GEOPOTENTIAL COEFFICIENTS GFZ (GAC)"@en ; "GRACE_GAC_L2_GRAV_GFZ_RL06"@en ; "180.0"^^xsd:float ; "podaac@podaac.jpl.nasa.gov"@en ; "PODAAC-GRGAC-20G06" ; "GRACE NON-TIDAL ATMOSPHERE AND OCEAN GEOPOTENTIAL COEFFICIENTS GFZ RELEASE 6.0 GAC"@en ; ""@en ; "Oceans"@en , "Geoscientific Information"@en ; "2018-08-06"^^xsd:date ; ""@en ; "Geographic Region"@en ; "Global"@en ; "Star Camera Assembly"@en , ""@en , "GRACE SuperSTAR Accelerometer"@en , "Gravity Recovery and Climate Experiment"@en , "GRACE K-Band Ranging System"@en ; "CEOS IDN DIF"@en ; "9.8"^^xsd:float ; "88.0"^^xsd:float ; "https://podaac-tools.jpl.nasa.gov/drive/files/allData/grace/docs/" ; "GRACE/GFZ"@en ; "Data Center Contact"@en ; ""@en , "GRACE KBR"@en , "GRACE"@en , "GRACE SCA"@en , "USA/NASA"@en , "GRACE ACC"@en ; "-88.0"^^xsd:float ; "2002-04-05"^^xsd:date ; "2017-07-01"^^xsd:date ; "GRAVITY/GRAVITATIONAL FIELD"@en ; "SOLID EARTH"@en ; "none"@en ; "GRAVITY"@en ; "6.0"^^xsd:float ; "-180.0"^^xsd:float . a base: ; owl:versionInfo "2020-09-16T19:36:14.265Z" ; "This dataset contains images of daily averaged ocean surface wind vectors derived from the gridded Level 3 QuikSCAT ocean surface wind vector dataset.

It carries ten sophisticated optical and radar instruments to provide continuous observation and monitoring of the Earth's land, atmosphere, oceans and ice caps. The Advanced Along-Track Scanning Radiometer (AATSR) onboard the Envisat spacecraft is designed to meet the challenging task of monitoring and detecting the climate change signal of sea surface temperature (SST). It builds on the success of its predecessor instruments on the European Remote-Sensing Satellite (ERS)-1, and ERS-2 satellites, and will lead to a multi-decade record of precise and accurate global SST measurements, thereby making a valuable contribution to the long-term climate record. The exceptionally high radiometric accuracy and stability of AATSR data are achieved through a number of unique features. A comprehensive pre-launch calibration programme, combined with continuous in-flight calibration, ensures that the data are continually corrected for sensor drift and degradation. A \"dual-view\" algorithm offering improved atmospheric correction by applying two different atmospheric path lengths is used to derive the SSTskin observations. The accuracies achieved with this configuration are further enhanced by using low-noise infrared detectors, cooled to their optimum operating temperature by a pair of Stirling-cycle coolers. With its high-accuracy, high-quality imagery and channels in the visible, near-infrared and thermal wavelengths, AATSR data will support many applications in addition to oceanographic and climate research, including a wide range of land-surface, cryosphere and atmospheric studies. See Llewellyn-Jones et al (2001) ESA bulletin 105, Feb 2001 for a full description. These AATSR L2P SST data are produced as part of the Group for High Resolution Sea Surface Temperature (GHRSST) Project according to the GHRSST-PP Data Processing Specification (GDS) version 1.5.
