Two data files contain monthly estimates of above-ground biomass for the period January 1969 to October 1969, one file for each treatment (burned and unburned plots). These files also provide one estimate of below-ground biomass. Another NPP data file contains monthly estimates of above- and below-ground biomass, LAI, and nitrogen content of living and dead leaves and stems and below-ground biomass for an unburned area of the Calabozo savanna for March 1986 to April 1987. The fourth data file contains precipitation and maximum/minimum temperature data from a nearby weather station at Estacion Biologica de Los Llanos (8.88 N, -67.32 W, Elevation 86 m) for the period 1968-1986. Harvest methods were used to estimate above- and below-ground biomass. Total NPP (above- plus below-ground productivity) was estimated at 682 g/m2/yr for unburned and 755 g/m2/yr for burned grassland plots in 1969. Later TNPP estimates (1986/87) for the unburned grassland ranged from 823 to 1,310 g/m2/yr. Revision Notes: Only the documentation for this data set has been modified. The data files have been checked for accuracy and are identical to those originally published in 1998.", "distribution": [{"@type": "dcat:Distribution", "downloadURL": "https://search.earthdata.nasa.gov/search?q=NPP_CLB_206&ac=true", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://doi.org/10.3334/ORNLDAAC/206", "format": "HTML", "mediaType": "text/html"}, {"@type": "dcat:Distribution", "downloadURL": "https://data.ornldaac.earthdata.nasa.gov/protected/bundle/NPP_CLB_206.zip", "format": "ZIP", "mediaType": "application/zip"}, {"@type": "dcat:Distribution", "downloadURL": "https://daac.ornl.gov/graphics/browse/project/square/npp_logo_square.png", "format": "PNG", "mediaType": "image/png"}, {"@type": "dcat:Distribution", "downloadURL": "https://data.ornldaac.earthdata.nasa.gov/public/npp/grassland/NPP_CLB/comp/NPP_CLB.pdf", "format": "PDF", "mediaType": "application/pdf"}, {"@type": "dcat:Distribution", "conformsTo": "http://www.isotc211.org/2005/gmi", "description": "The metadata's original source.", "downloadURL": "https://cmr.earthdata.nasa.gov/search/concepts/C2752562626-ORNL_CLOUD.iso19115", "format": "ISO", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "10.3334/ORNLDAAC/206", "keyword": ["earth-science-ecological-dynamics-biosphere-ecosystem-functions-biomass-dynamics", "earth-science-ecological-dynamics-biosphere-ecosystem-functions-primary-production", "earth-science-vegetation-biosphere-biomass"], "license": "https://www.usa.gov/government-works", "modified": "2026-04-06", "programCode": ["026:000"], "publisher": {"@type": "org:Organization", "name": "ORNL_DAAC"}, "spatial": "[[{\"WestBoundingCoordinate\":-67.42,\"NorthBoundingCoordinate\":8.93,\"EastBoundingCoordinate\":-67.42,\"SouthBoundingCoordinate\":8.93}],\"CARTESIAN\"]", "temporal": "1968-01-01/1987-04-15", "theme": ["Earth Science"], "title": "NPP Grassland: Calabozo, Venezuela, 1969-1987, R1"}
