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. This product includes 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.", "distribution": [{"@type": "dcat:Distribution", "description": "Earthdata Search allows users to search, discover, visualize, refine, and access NASA Earth Observation data.", "downloadURL": "https://search.earthdata.nasa.gov/search?q=C1373412071-LPDAAC_ECS", "format": "HTML", "mediaType": "text/html", "title": "Download this dataset through Earthdata Search"}, {"@type": "dcat:Distribution", "description": "OPeNDAP provides direct access to data via HTTPS.", "downloadURL": "https://opendap.cr.usgs.gov/opendap/hyrax/VNP09CMG.001/contents.html", "format": "HTML", "mediaType": "text/html", "title": "Use OPeNDAP to access the dataset's data"}, {"@type": "dcat:Distribution", "description": "Search results for publications that cite this dataset by its DOI.", "downloadURL": "https://scholar.google.com/scholar?q=10.5067%2FVIIRS%2FVNP09CMG.001", "format": "HTML", "mediaType": "text/html", "title": "Google Scholar search results"}, {"@type": "dcat:Distribution", "description": "The ATBD provides physical theory and mathematical procedures for the calculations used to produce the data products.", "downloadURL": "https://lpdaac.usgs.gov/documents/122/VNP09_ATBD.pdf", "format": "PDF", "mediaType": "application/pdf", "title": "View this dataset's algorithm theoretical basis document"}, {"@type": "dcat:Distribution", "description": "The LP DAAC product page provides information on Science Data Set layers and links for user guides, ATBDs, data access, tools, customer support, etc.", "downloadURL": "https://doi.org/10.5067/VIIRS/VNP09CMG.001", "format": "HTML", "mediaType": "text/html", "title": "This dataset's landing page"}, {"@type": "dcat:Distribution", "description": "The LP DAAC website provides detailed information on discovery, distribution, access, and support of land data products.", "downloadURL": "https://lpdaac.usgs.gov/", "format": "HTML", "mediaType": "text/html", "title": "The dataset's project home page"}, {"@type": "dcat:Distribution", "description": "The technical information in the Version 1.1 User's Guide enables users to interpret and use the data products.", "downloadURL": "https://lpdaac.usgs.gov/documents/123/VNP09_User_Guide_V1.1.pdf", "format": "PDF", "mediaType": "application/pdf", "title": "View this dataset's user's guide"}, {"@type": "dcat:Distribution", "description": "The technical information in the Version 1.6 User's Guide enables users to interpret and use the data products.", "downloadURL": "https://lpdaac.usgs.gov/documents/124/VNP09_User_Guide_V1.6.pdf", "format": "PDF", "mediaType": "application/pdf", "title": "View this dataset's user's guide"}, {"@type": "dcat:Distribution", "description": "USGS EarthExplorer provides users the ability to query, search, and order products available from the LP DAAC.", "downloadURL": "https://earthexplorer.usgs.gov/", "format": "HTML", "mediaType": "text/html", "title": "Download this dataset through USGS Earth Explorer"}, {"@type": "dcat:Distribution", "description": "Validation at stage 1 has been achieved for the VIIRS surface reflectance product suite.", "downloadURL": "https://viirsland.gsfc.nasa.gov/Val/LSR_Val.html", "format": "HTML", "mediaType": "text/html", "title": "View this dataset's science data product validation documentation"}], "identifier": "C1373412071-LPDAAC_ECS", "issued": "2017-02-15", "keyword": ["earth-science", "land-surface", "surface-radiative-properties"], "landingPage": "https://doi.org/10.5067/VIIRS/VNP09CMG.001", "language": ["en-US"], "modified": "2025-07-17", "programCode": ["026:001"], "publisher": {"@type": "org:Organization", "name": "LP DAAC"}, "spatial": "-180.0 -90.0 180.0 90.0", "temporal": "2012-01-19T00:00:00Z/2022-01-17T00:00:00Z", "theme": ["NPP-JPSS", "geospatial"], "title": "VIIRS/NPP Surface Reflectance Daily L3 Global 0.05 Deg CMG V001"}
