Since SiFSAP is an FOV-based algorithm, its product variables have an additional dimension which represents the number of FOVs. For CrIS instrument, there are 9 FOVs for each Field of Regard (FOR). The SiFSAP L3 products contain a variety of geophysical parameters retrieved from IR/MW sounder suites measurements, including atmospheric temperature profiles, water vapor, ozone profiles, clouds, and surface properties. \n\nThis daily one half degree latitude by one half degree longitude level-3 product starts with level-2 retrieval products with QC values of 0 (best), 1 (good), and 2 (don't use). The Level-3 products maximize the yield of each individual variable and level by collecting all cases where the corresponding Level 2 quality control from the top of the atmosphere down to the level where the QC determines that the value is\u00a00\u00a0(best) or 1 (good). Below this level, the data is rejected. This gives the greatest possible yield for any given level and variable.", "distribution": [{"@type": "dcat:Distribution", "conformsTo": "http://www.isotc211.org/2005/gmi", "description": "The metadata's original source.", "downloadURL": "https://cmr.earthdata.nasa.gov/search/concepts/C2816205963-GES_DISC.iso19115", "format": "ISO", "mediaType": "text/xml", "title": "Original Metadata"}, {"@type": "dcat:Distribution", "downloadURL": "https://disc.gsfc.nasa.gov/datacollection/SNDRSNIML3SDSFSP_2.html", "format": "HTML", "mediaType": "text/html"}, {"@type": "dcat:Distribution", "downloadURL": "https://docserver.gesdisc.eosdis.nasa.gov/public/project/Images/SNDRSNIML3SDSFSP_2.jpg", "format": "JPEG", "mediaType": "image/jpeg"}, {"@type": "dcat:Distribution", "downloadURL": "https://docserver.gesdisc.eosdis.nasa.gov/public/project/Sounder/SiFSAP.ATBD.egusphere-2023-879.pdf", "format": "PDF", "mediaType": "application/pdf"}, {"@type": "dcat:Distribution", "downloadURL": "https://docserver.gesdisc.eosdis.nasa.gov/public/project/Sounder/SiFSAP.L3.V2.README.pdf", "format": "PDF", "mediaType": "application/pdf"}, {"@type": "dcat:Distribution", "downloadURL": "https://search.earthdata.nasa.gov/search/granules?p=C2816205963-GES_DISC", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://sounder.gesdisc.eosdis.nasa.gov/data/SiFSAP/SNDRSNIML3SDSFSP.2", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://sounder.gesdisc.eosdis.nasa.gov/opendap/SiFSAP/SNDRSNIML3SDSFSP.2/", "format": "BIN", "mediaType": "application/octet-stream"}], "identifier": "10.5067/EXABRGM029LU", "keyword": ["earth-science-altitude-atmosphere-geopotential-height", "earth-science-altitude-atmosphere-tropopause", "earth-science-atmospheric-chemistry-atmosphere-carbon-and-hydrocarbon-compounds", "earth-science-atmospheric-chemistry-atmosphere-oxygen-compounds", "earth-science-atmospheric-pressure-atmosphere-surface-pressure", "earth-science-atmospheric-temperature-atmosphere-surface-temperature", "earth-science-atmospheric-temperature-atmosphere-upper-air-temperature", "earth-science-atmospheric-water-vapor-atmosphere-water-vapor-indicators", "earth-science-atmospheric-water-vapor-atmosphere-water-vapor-profiles", "earth-science-clouds-atmosphere-cloud-microphysics", "earth-science-clouds-atmosphere-cloud-properties", "earth-science-clouds-atmosphere-cloud-radiative-transfer", "earth-science-ocean-temperature-oceans-sea-surface-temperature", "earth-science-surface-radiative-properties-land-surface-emissivity", "earth-science-surface-thermal-properties-land-surface-skin-temperature"], "license": "https://www.usa.gov/government-works", "modified": "2026-06-22", "programCode": ["026:000"], "publisher": {"@type": "org:Organization", "name": "NASA/GSFC/SED/ESD/TISL/GESDISC"}, "spatial": "[\"CARTESIAN\", [{\"WestBoundingCoordinate\": -180, \"NorthBoundingCoordinate\": 90, \"EastBoundingCoordinate\": 180, \"SouthBoundingCoordinate\": -90}]]", "temporal": "2015-11-02/2026-06-15", "theme": ["Earth Science"], "title": "Sounder SIPS: Suomi NPP CrIMSS Level 3 Specific Quality Control Gridded Daily SiFSAP V2 (SNDRSNIML3SDSFSP) at GES DISC"}
