CENTURY is composed of a soil organic matter/ decomposition submodel, a water budget model, a grassland/crop submodel, a forest production submodel, and management and events scheduling functions. It computes the flow of carbon, nitrogen, phosphorus, and sulfur through the model's compartments.", "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/C2956545669-ORNL_CLOUD.iso19115", "format": "ISO", "mediaType": "text/xml", "title": "Original Metadata"}, {"@type": "dcat:Distribution", "downloadURL": "https://daac.ornl.gov/graphics/browse/project/square/model-archive_logo_square.png", "format": "PNG", "mediaType": "image/png"}, {"@type": "dcat:Distribution", "downloadURL": "https://data.ornldaac.earthdata.nasa.gov/protected/bundle/century_vemap_m4_820.zip", "format": "ZIP", "mediaType": "application/zip"}, {"@type": "dcat:Distribution", "downloadURL": "https://data.ornldaac.earthdata.nasa.gov/public/model_archive/century_vemap_m4/comp/CENTURY_VEMAP_simulation_readme.pdf", "format": "PDF", "mediaType": "application/pdf"}, {"@type": "dcat:Distribution", "downloadURL": "https://data.ornldaac.earthdata.nasa.gov/public/model_archive/century_vemap_m4/comp/Century_Users_Manual_V4.pdf", "format": "PDF", "mediaType": "application/pdf"}, {"@type": "dcat:Distribution", "downloadURL": "https://data.ornldaac.earthdata.nasa.gov/public/model_archive/century_vemap_m4/comp/century_vemap.pdf", "format": "PDF", "mediaType": "application/pdf"}, {"@type": "dcat:Distribution", "downloadURL": "https://doi.org/10.3334/ORNLDAAC/820", "format": "HTML", "mediaType": "text/html"}, {"@type": "dcat:Distribution", "downloadURL": "https://search.earthdata.nasa.gov/search?q=century_vemap_m4_820&ac=true", "format": "BIN", "mediaType": "application/octet-stream"}], "identifier": "10.3334/ORNLDAAC/820", "keyword": ["earth-science-ecosystems-biosphere-anthropogenic-human-influenced-ecosystems-agricultural-lands", "earth-science-ecosystems-biosphere-terrestrial-ecosystems-forests", "earth-science-ecosystems-biosphere-terrestrial-ecosystems-grasslands", "earth-science-ecosystems-biosphere-terrestrial-ecosystems-savannas", "earth-science-soils-agriculture-carbon", "earth-science-soils-agriculture-nitrogen", "earth-science-soils-agriculture-phosphorus", "earth-science-soils-agriculture-sulfur"], "license": "https://www.usa.gov/government-works", "modified": "2026-05-11", "programCode": ["026:000"], "publisher": {"@type": "org:Organization", "name": "ORNL_DAAC"}, "spatial": "[[{\"WestBoundingCoordinate\":-180.0,\"NorthBoundingCoordinate\":90.0,\"EastBoundingCoordinate\":180.0,\"SouthBoundingCoordinate\":-90.0}],\"CARTESIAN\"]", "temporal": "1995-01-01/1995-01-01", "theme": ["Earth Science"], "title": "CENTURY: Modeling Ecosystem Responses to Climate Change, Version 4 (VEMAP 1995)"}
