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 onGoing Helpdesk podaac@podaac.jpl.nasa.gov pointOfContact NASA/JPL/PODAAC originator NASA/JPL/PODAAC > Physical Oceanography Distributed Active Archive Center, Jet Propulsion Laboratory, NASA distributor funder author Description: Thumbnail URLContentType: VisualizationURL Type: GET RELATED VISUALIZATION Browse Oceanographic geographical features GEMET - INSPIRE themes, version 1.0 2018-07-27 publication geonetwork.thesaurus.external.theme.httpinspireeceuropaeutheme-theme Ocean Temperature Cersat - Parameter 2019-12-17 publication geonetwork.thesaurus.local.theme.cersat_parameter Cersat - Latency 2021-03-04 publication geonetwork.thesaurus.local.theme.cersat_latency GHRSST Cersat - Project 2022-04-04 publication geonetwork.thesaurus.local.theme.cersat_project /Ocean Temperature/Sea Surface Temperature Cersat - GCMD parameter 2022-04-05 publication geonetwork.thesaurus.external.theme.GCMDparameter 0.75 1 -180.0 180.0 -90.0 90.0 Global 2011-11-21T00:00:00.000Z earliest_granule_start_time Earliest Granule Start Time for dataset. 2012-01-05T05:06:01.000Z latest_granule_end_time Latest Granule Stop/End Time for dataset. 2022-01-04T09:59:58.000Z data_latency Dataset Latency 6 Series Name Dataset citation series name GHRSST Level 2P Global Skin Sea Surface Temperature from VIIRS produced by JPL Persistent ID Dataset Persistent ID PODAAC-GHVRS-2PJ62 L2P Format: Not provided https://podaac-tools.jpl.nasa.gov/drive/files/allData/ghrsst/sw/generic_nc_readers WWW:LINK Generic netCDF readers provided in multiple programming languages HTTPS https://podaac-tools.jpl.nasa.gov/hitide/ WWW:LINK HIgh-level Tool for Interactive Data Extraction HTTPS https://podaac.jpl.nasa.gov/ws/search/granule/?datasetId=PODAAC-GHVRS-2PJ62 WWW:LINK Search Granule HTTPS https://podaac-tools.jpl.nasa.gov/drive/files/allData/ghrsst/data/GDS2/L2P/VIIRS_NPP/JPL/v2016.2 WWW:LINK PO.DAAC Drive HTTPS Format: Not provided Format: Not provided MimeType: application/xml Format: Not provided MimeType: text/html http://doi.org/10.5067/GHVRS-2PJ62 DOI Digital Object Identifier (DOI) PrecisionOfSeconds
