The VNP13 data products are designed after the Moderate Resolution Imaging Spectroradiometer (MODIS) Terra and Aqua Vegetation Indices product suite to promote the continuity of the Earth Observation System (EOS) mission.\n\nThe product consists of eighteen distinct variables in total. The VNP13 algorithm process produces three vegetation indices: The Normalized Difference Vegetation Index (NDVI), the Enhanced Vegetation Index (EVI), and the Enhanced Vegetation Index-2 (EVI2). NDVI is one of the longest continual remotely sensed time series observations, using both the red and near-infrared (NIR) bands. EVI is a slightly different vegetation index that is more sensitive to canopy cover, while NDVI is more sensitive to chlorophyll. EVI2 is a reformation of the standard 3-band EVI, using the red band and NIR band. This reformation addresses arising issues when comparing VIIRS EVI to other EVI models that do not include a blue band. EVI2 will eventually become the standard EVI. \n\nAlong with the three Vegetation Indices variables, this product also includes variables for the standard deviations of each Vegetation Index; NIR reflectance; three shortwave infrared (SWIR) reflectance; red, blue, and green reflectance; number of pixels, number of pixels used; pixel reliability; average sun angle, and a quality variable. Two low resolution browse images are also available for each VJ113C2 product: EVI and NDVI.\n\nKnown Issues\n* Due to missing critical inputs, this product lacks coverage for tiles h33v07 and h18v14, which are located over water.\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 the User Guide and ATBD.", "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/C2545310866-LPCLOUD.iso19115", "format": "ISO", "mediaType": "text/xml", "title": "Original Metadata"}, {"@type": "dcat:Distribution", "downloadURL": "https://data.lpdaac.earthdatacloud.nasa.gov/lp-prod-public/VJ113C2.002/VJ113C2.A2024032.002.2024078125401/BROWSE.VJ113C2.A2024032.002.2024078125401.1.jpg", "format": "JPEG", "mediaType": "image/jpeg"}, {"@type": "dcat:Distribution", "downloadURL": "https://doi.org/10.5067/VIIRS/VJ113C2.002", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://ladsweb.modaps.eosdis.nasa.gov/filespec/VIIRS/1/VJ113C2", "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://lpdaac.usgs.gov/documents/1372/VNP13_User_Guide_ATBD_V2.1.2.pdf", "format": "PDF", "mediaType": "application/pdf"}, {"@type": "dcat:Distribution", "downloadURL": "https://search.earthdata.nasa.gov/search/granules?p=C2545310866-LPCLOUD", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://viirsland.gsfc.nasa.gov/Val/VI_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/VJ113C2.002", "keyword": ["earth-science-vegetation-biosphere-plant-phenology", "earth-science-vegetation-biosphere-vegetation-index"], "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": "2018-01-01/2026-06-15", "theme": ["Earth Science"], "title": "VIIRS/JPSS1 Vegetation Indices Monthly L3 Global 0.05Deg CMG V002"}
