Estimates were produced for the following regions and periods: eastern and western CONUS (2010-2019), western Europe (2010-2014 and 2017-2018), eastern Asia, eastern China, eastern Australia, South America, and Central Africa (2017-2018). Modeled CO2 flux components include gross primary production (GPP), ecosystem respiration (Reco), and net ecosystem exchange (NEE). Four-day means of GPP are estimated from solar-induced fluorescence (SIF) and biome-specific GPP-SIF relationships. Daily estimates of Reco are included. In addition, GPP and Reco were downscaled to hourly estimates and used to generate hourly NEE. Uncertainties for 4-day GPP and daily Reco estimates are provided. The input data streams included 500 m MODIS-based annual land cover classification, 0.05 degree spatiotemporally contiguous SIF, above-ground biomass (AGB) from GlobBiomass, eddy-covariance (EC) flux measurements, and gridded products of air and soil temperatures.", "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/C2515937777-ORNL_CLOUD.iso19115", "format": "ISO", "mediaType": "text/xml", "title": "Original Metadata"}, {"@type": "dcat:Distribution", "downloadURL": "https://daac.ornl.gov/NACP/guides/Biogenic_CO2flux_SIF_SMUrF_Fig1.png", "format": "PNG", "mediaType": "image/png"}, {"@type": "dcat:Distribution", "downloadURL": "https://data.ornldaac.earthdata.nasa.gov/public/nacp/Biogenic_CO2flux_SIF_SMUrF/comp/Biogenic_CO2flux_SIF_SMUrF.pdf", "format": "PDF", "mediaType": "application/pdf"}, {"@type": "dcat:Distribution", "downloadURL": "https://doi.org/10.3334/ORNLDAAC/1899", "format": "HTML", "mediaType": "text/html"}, {"@type": "dcat:Distribution", "downloadURL": "https://opendap.earthdata.nasa.gov/", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://search.earthdata.nasa.gov/search/granules?p=C2515937777-ORNL_CLOUD", "format": "BIN", "mediaType": "application/octet-stream"}], "identifier": "10.3334/ORNLDAAC/1899", "keyword": ["earth-science-ecosystems-biosphere-anthropogenic-human-influenced-ecosystems", "earth-science-ecosystems-biosphere-terrestrial-ecosystems", "earth-science-human-settlements-human-dimensions-urban-areas", "earth-science-land-use-land-cover-land-surface-land-use-land-cover-classification", "earth-science-soils-land-surface-carbon", "earth-science-soils-land-surface-soil-productivity", "earth-science-soils-land-surface-soil-respiration", "earth-science-vegetation-biosphere-solar-induced-fluorescence"], "license": "https://www.usa.gov/government-works", "modified": "2026-06-23", "programCode": ["026:000"], "publisher": {"@type": "org:Organization", "name": "ORNL_DAAC"}, "spatial": "[\"CARTESIAN\", [{\"WestBoundingCoordinate\": -125.0, \"NorthBoundingCoordinate\": 60.0, \"EastBoundingCoordinate\": 155.0, \"SouthBoundingCoordinate\": -40.0}]]", "temporal": "2010-01-01/2019-12-31", "theme": ["Earth Science"], "title": "Urban Biogenic CO2 fluxes: GPP, Reco and NEE Estimates from SMUrF, 2010-2019"}
