The ACSPO SNPP/VIIRS L3U (Level 3 Uncollated) product is a gridded version of the ACSPO NPP/VIIRS L2P product available here https://doi.org/10.5067/GHVRS-2PO28 . The L3U output files are 10-minute granules in netCDF4 format, compliant with the Group for High Resolution Sea Surface Temperature (GHRSST) Data Specification version 2 (GDS2). There are 144 granules per 24hr interval, with a total data volume of 0.5GB/day. Fill values are reported at all invalid pixels, including pixels with >5 km inland. For each valid water pixel (defined as ocean, sea, lake or river, and up to 5 km inland), the following layers are reported: SSTs, a subset of l2p_flags (including day/night, land, ice, twilight, and glint flags), wind speed, and ACSPO SST minus reference (Canadian Met Centre 0.1deg L4 SST; available at https://www.doi.org/10.5067/GHCMC-4FM03). Only L2P SSTs with QL=5 were gridded, so all valid SSTs are recommended for the users. Per GDS2 specifications, two additional Sensor-Specific Error Statistics layers (SSES bias and standard deviation) are reported in each pixel with valid SST. The ACSPO VIIRS SST products are monitored and validated against in situ data in the NOAA iQuam system (https://www.star.nesdis.noaa.gov/socd/sst/iquam ) using the NOAA SQUAM system (https://www.star.nesdis.noaa.gov/socd/sst/squam ). BTs are monitored against RTM simulation in MICROS (https://www.star.nesdis.noaa.gov/socd/sst/micros ). Quality of SST imagery and clear-sky mask are evaluated in the NOAA ARMS system (https://www.star.nesdis.noaa.gov/socd/sst/arms ). The v2.80 is an updated version from the v2.61 with several L2P algorithm improvements including two added thermal front layers, mitigated warm biases in the high latitudes, and improved clear-sky mask. onGoing Helpdesk podaac@podaac.jpl.nasa.gov pointOfContact DOC/NOAA/NESDIS/OSPO > Office of Satellite and Product Operations, NESDIS, NOAA, U.S. Department of Commerce originator NASA/JPL/PODAAC > Physical Oceanography Distributed Active Archive Center, Jet Propulsion Laboratory, NASA distributor NOAA/NESDIS funder Alexander Ignatov DOC/NOAA/NESDIS/STAR > Center for Satellite Applications and Research, NESDIS, NOAA, U.S. Department of Commerce alex.ignatov@noaa.gov author Description: Thumbnail URLContentType: VisualizationURL Type: GET RELATED VISUALIZATION Browse netCDF-4 FormatType: Native AverageFileSize: 4.0 AverageFileSizeUnit: MB Oceanographic geographical features GEMET - INSPIRE themes, version 1.0 2018-07-27 publication geonetwork.thesaurus.external.theme.httpinspireeceuropaeutheme-theme Ocean Temperature Cersat - Parameter 2023-03-16 publication geonetwork.thesaurus.local.theme.cersat_parameter Less than 12 hours Cersat - Latency 2023-06-06 publication geonetwork.thesaurus.local.theme.cersat_latency GHRSST Cersat - Project 2023-03-31 publication geonetwork.thesaurus.local.theme.cersat_project /Ocean Temperature/Sea Surface Temperature Cersat - GCMD parameter 2022-04-05 publication geonetwork.thesaurus.external.theme.GCMDparameter NOAA STAR, Gridded Uncollated (L3U) Sea Surface Temperature from S-NPP VIIRS 2012-onwards, https://doi.org/10.5067/GHVRS-3UO28, data for [extracted period], [extracted domain], accessed [download date] from [distributor/distribution mean] 0.02 1 -180.00 180.00 -90.00 90.00 Global 2012-02-01T00:00:00.000Z 10-min granule earliest_granule_start_time Earliest Granule Start Time for dataset. 2012-02-01T00:00:00.000Z latest_granule_end_time Latest Granule Stop/End Time for dataset. 2021-05-21T14:09:59.000Z data_latency Dataset Latency 6 Series Name Dataset citation series name GHRSST Level 3U OSPO dataset from VIIRS on S-NPP Satellite (GDS v2) Persistent ID Dataset Persistent ID PODAAC-GHVRS-3UO61 L3 Format: Not provided MimeType: text/html https://cmr.earthdata.nasa.gov/virtual-directory/collections/C2147485059-POCLOUD WWW:LINK PODAAC Earthdata cloud access HTTPS https://search.earthdata.nasa.gov/search/granules?p=C2147485059-POCLOUD WWW:LINK PODAAC Browse granule search results in Earthdata Search HTTPS Format: Not provided MimeType: text/html https://doi.org/10.1175/2010JTECHA1413.1 WWW:LINK Other document Clear-Sky Mask for the Advanced Clear-Sky Processor for Oceans https://doi.org/10.1002/2013JD020637 WWW:LINK Other document Evaluation and selection of SST regression algorithms for JPSS VIIRS:Selection of SST Regression Algorithms https://doi.org/10.1175/JTECH-D-15-0166.1 WWW:LINK Other document Sensor-Specific Error Statistics for SST in the Advanced Clear-Sky Processor for Oceans https://doi.org/10.3390/rs14143476 WWW:LINK Other document JPSS VIIRS SST Reanalysis Version 3 https://doi.org/10.1117/1.JRS.11.032405 WWW:LINK Other document JPSS VIIRS level 3 uncollated sea surface temperature product at NOAA https://podaac.jpl.nasa.gov/dataset/VIIRS_NPP-STAR-L3U-v2.80 WWW:LINK Other document See "Documentation" tab at: http://doi.org/10.5067/GHVRS-3UO28 DOI Digital Object Identifier (DOI) PrecisionOfSeconds
