The data are part of the Tropospheric Chemical Reanalysis v2 (TCR-2) for the period 2005-2021. TCR-2 uses JPL's Multi-mOdel Multi-cOnstituent Chemical (MOMO-Chem) data assimilation framework that simultaneously optimizes both concentrations and emissions of multiple species from multiple satellite sensors. The data files are written in the netCDF version 4 file format, and each file contains a year of data at 2-hourly resolution, and a spatial resolution of 1.125 x 1.125 degrees. The principal investigator for the TCR-2 data is Miyazaki, Kazuyuki.", "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/C2816184410-GES_DISC.iso19115", "format": "ISO", "mediaType": "text/xml", "title": "Original Metadata"}, {"@type": "dcat:Distribution", "downloadURL": "https://disc.gsfc.nasa.gov/datacollection/TRPSCRAERSO42H2D_1.html", "format": "HTML", "mediaType": "text/html"}, {"@type": "dcat:Distribution", "downloadURL": "https://docserver.gesdisc.eosdis.nasa.gov/public/project/TROPESS/images/TRPSCRAERSO42H2D_Sample.png", "format": "PNG", "mediaType": "image/png"}, {"@type": "dcat:Distribution", "downloadURL": "https://search.earthdata.nasa.gov/search?q=TRPSCRAERSO42H2D_1", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://tes.jpl.nasa.gov/tes/chemical-reanalysis/", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://tropess.gesdisc.eosdis.nasa.gov/data/TCR2_2HR_SURFCONCS/TRPSCRAERSO42H2D.1/", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://tropess.gesdisc.eosdis.nasa.gov/data/TCR2_2HR_SURFCONCS/TRPSCRAERSO42H2D.1/doc/TROPESS_ChemReanalysis_Forward_Stream_README.pdf", "format": "PDF", "mediaType": "application/pdf"}, {"@type": "dcat:Distribution", "downloadURL": "https://tropess.gesdisc.eosdis.nasa.gov/opendap/TCR2_2HR_SURFCONCS/TRPSCRAERSO42H2D.1/contents.html", "format": "HTML", "mediaType": "text/html"}], "identifier": "10.5067/9K96YRHCV5A5", "keyword": ["aerosols-atmosphere", "atmosphere-aerosol-particle-properties", "earth-science-aerosols-atmosphere-aerosol-particle-properties-aerosol-concentration", "earth-science-aerosols-atmosphere-sulfate-particles-aerosols", "sulfate-particles-aerosol-concentration"], "license": "https://www.usa.gov/government-works", "modified": "2026-04-21", "programCode": ["026:000"], "publisher": {"@type": "org:Organization", "name": "NASA/GSFC/SED/ESD/TISL/GESDISC"}, "spatial": "[\"CARTESIAN\",[{\"WestBoundingCoordinate\":-180,\"NorthBoundingCoordinate\":90,\"EastBoundingCoordinate\":180,\"SouthBoundingCoordinate\":-90}]]", "temporal": "2005-01-01/2021-12-31", "theme": ["Earth Science"], "title": "TROPESS Chemical Reanalysis Surface Aerosol SO4 2-Hourly 2-dimensional Product V1 (TRPSCRAERSO42H2D) at GES DISC"}
