The LAI variable defines the number of equivalent layers of leaves relative to a unit of ground area, whereas FPAR measures the proportion of available radiation in the photosynthetically active wavelengths that are absorbed by a canopy. Both variables are used as satellite-derived parameters for calculating surface photosynthesis, evapotranspiration, and net primary production, which in turn are used to calculate terrestrial energy, carbon, water cycle processes, and biogeochemistry of vegetation.", "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/C2055696477-LAADS.iso19115", "format": "ISO", "mediaType": "text/xml", "title": "Original Metadata"}, {"@type": "dcat:Distribution", "downloadURL": "http://accweb.nascom.nasa.gov/project/docs/User_guide_C5_GFS.pdf", "format": "PDF", "mediaType": "application/pdf"}, {"@type": "dcat:Distribution", "downloadURL": "https://ladsweb.modaps.eosdis.nasa.gov/archive/allData/6/MOD15A2GFS/", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://ladsweb.modaps.eosdis.nasa.gov/opendap/RemoteResources/laads/allData/6/MOD15A2GFS/contents.html", "format": "HTML", "mediaType": "text/html"}, {"@type": "dcat:Distribution", "downloadURL": "https://ladsweb.modaps.eosdis.nasa.gov/search/order/1/MOD15A2GFS--6", "format": "BIN", "mediaType": "application/octet-stream"}], "identifier": "10.5067/MODIS/MOD15A2GFS.006", "keyword": ["earth-science-vegetation-biosphere-leaf-characteristics", "earth-science-vegetation-biosphere-photosynthetically-active-radiation", "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": "NASA/GSFC/SED/ESD/HBSL/BISB/LAADS;NASA/GSFC/SED/ESD/HBSL/BISB/MODAPS"}, "spatial": "[\"CARTESIAN\", [{\"NorthBoundingCoordinate\": 90.0, \"WestBoundingCoordinate\": -180.0, \"EastBoundingCoordinate\": 180.0, \"SouthBoundingCoordinate\": -90.0}]]", "temporal": "2001-01-01/2026-06-15", "theme": ["Earth Science"], "title": "MODIS/Terra Gap-Filled, Smoothed LAI-FPAR 8-Day L4 Global 1km SIN Grid"}
