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.\n\nThe data files are written in the netCDF version 4 file format, and each file contains a year of data at 6-hourly resolution, and a spatial resolution of 1.125 x 1.125 degrees at 27 pressure levels between 1000 and 60 hPa. The principal investigator for the TCR-2 data is Miyazaki, Kazuyuki.", "distribution": [{"@type": "dcat:Distribution", "description": "Access the dataset landing page from the GES DISC website.", "downloadURL": "https://disc.gsfc.nasa.gov/datacollection/TRPSCRO3S6H3D_1.html", "format": "HTML", "mediaType": "text/html", "title": "This dataset's landing page"}, {"@type": "dcat:Distribution", "description": "Chemical Reanalysis Project Home Page.", "downloadURL": "https://tes.jpl.nasa.gov/tes/chemical-reanalysis/", "format": "HTML", "mediaType": "text/html", "title": "The dataset's project home page"}, {"@type": "dcat:Distribution", "description": "Search results for publications that cite this dataset by its DOI.", "downloadURL": "https://scholar.google.com/scholar?q=10.5067%2F77WYU7FH83VS", "format": "HTML", "mediaType": "text/html", "title": "Google Scholar search results"}, {"@type": "dcat:Distribution", "description": "TROPESS CrIS-SNPP Los Angeles Megacity (Forward Stream, Summary Product) at 681 hPa on 01 April 2021.", "downloadURL": "https://docserver.gesdisc.eosdis.nasa.gov/public/project/TROPESS/images/TRPSCRO3S6H3D_Sample.png", "format": "PNG", "mediaType": "image/png", "title": "Get a related visualization"}, {"@type": "dcat:Distribution", "description": "Use the Earthdata Search Client to find and retrieve data sets across multiple data centers.", "downloadURL": "https://search.earthdata.nasa.gov/search?q=TRPSCRO3S6H3D_1", "format": "HTML", "mediaType": "text/html", "title": "Download this dataset through Earthdata Search"}], "identifier": "C2837624942-GES_DISC", "issued": "2023-01-09", "keyword": ["atmosphere", "atmospheric-chemistry", "earth-science"], "landingPage": "https://doi.org/10.5067/77WYU7FH83VS", "language": ["en-US"], "modified": "2025-07-17", "programCode": ["026:001"], "publisher": {"@type": "org:Organization", "name": "NASA/GSFC/SED/ESD/GCDC/GESDISC"}, "references": ["https://doi.org/10.1126/sciadv.abf7460"], "spatial": "-180.0 -90.0 180.0 90.0", "temporal": "2005-01-01T00:00:00Z/2024-02-12T00:00:00Z", "theme": ["TROPESS", "geospatial"], "title": "TROPESS Chemical Reanalysis Ozone Spread 6-Hourly 3-dimensional Product V1 (TRPSCRO3S6H3D) at GES DISC"}
