Data are provided for three imagery bands (I1-I3) and nine moderate resolution bands (M1-M5, M7, M8, M10, M11) at 0.05 degree (~5,600 meter) resolution. The data are corrected for atmospheric conditions such as the effects of molecular gases, including ozone and water vapor, and for the effects of atmospheric aerosols. This product uses a weighted average of the best quality observation and is formatted as a CMG for use in climate simulation models. \n\nThis product includes a total of 33 variables, including the twelve reflectance bands, five moderate resolution brightness temperature bands (M12-M16) and information layers representing relative azimuth angle, sensor zenith angle, solar zenith angle, reflectance band quality, time of day, and number mapping. \n\nKnown Issues\n\n* For complete information about known issues please refer to the [MODIS/VIIRS Land Quality Assessment website](https://landweb.modaps.eosdis.nasa.gov/knownissue?sensor=VIIRS) and in Section 4.0 of the User Guide.", "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/C2763377747-LPCLOUD.iso19115", "format": "ISO", "mediaType": "text/xml", "title": "Original Metadata"}, {"@type": "dcat:Distribution", "downloadURL": "https://doi.org/10.5067/VIIRS/VNP21A1N.001", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://landweb.modaps.eosdis.nasa.gov", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://landweb.modaps.eosdis.nasa.gov/cgi-bin/NPP_QA/NPPpage.cgi?fileName=maturity&subdir=forPage", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://lpdaac.usgs.gov/documents/1332/VNP21_ATBD_V1.pdf", "format": "PDF", "mediaType": "application/pdf"}, {"@type": "dcat:Distribution", "downloadURL": "https://lpdaac.usgs.gov/documents/429/VNP21_User_Guide_V1.pdf", "format": "PDF", "mediaType": "application/pdf"}, {"@type": "dcat:Distribution", "downloadURL": "https://viirsland.gsfc.nasa.gov/Val/LST_Val.html", "format": "HTML", "mediaType": "text/html"}, {"@type": "dcat:Distribution", "downloadURL": "https://viirsland.gsfc.nasa.gov/Val_overview.html", "format": "HTML", "mediaType": "text/html"}, {"@type": "dcat:Distribution", "downloadURL": "https://www.earthdata.nasa.gov/centers/lp-daac", "format": "BIN", "mediaType": "application/octet-stream"}], "identifier": "10.5067/VIIRS/VNP09CMG.002", "keyword": ["earth-science-surface-radiative-properties-land-surface-reflectance"], "license": "https://www.usa.gov/government-works", "modified": "2026-06-23", "programCode": ["026:000"], "publisher": {"@type": "org:Organization", "name": "LP DAAC;NASA/GSFC/SED/ESD/TISL/LandSIPS"}, "spatial": "[\"CARTESIAN\", [{\"NorthBoundingCoordinate\": 90, \"WestBoundingCoordinate\": -180, \"EastBoundingCoordinate\": 180, \"SouthBoundingCoordinate\": -90}]]", "temporal": "2012-01-17/2026-06-15", "theme": ["Earth Science"], "title": "VIIRS/NPP Surface Reflectance Daily L3 Global 0.05Deg CMG V002"}
