Because this simulation is intended to serve as a reference Nature Run for Observing System Simulation Experiments (OSSEs, e.g., Errico et al., 2012) it will be referred to as the 7-km GEOS-5 Nature Run or 7-km G5NR. This simulation has been performed with the Ganymed version of GEOS- 5, more specifically with CVS Tag wmp-Ganymed-4_0_BETA8. In addition to standard meteorological parameters (wind, temperature, moisture, surface pressure), this simulation includes 15 aerosol tracers (dust, sea-salt, sulfate, black and organic carbon), O3, CO and CO2. This model simulation is driven by prescribed sea-surface temperature and sea-ice, as well as surface emissions and uptake of aerosols and trace gases, including daily volcanic and biomass burning emissions, biogenic sources and sinks of CO2, and high-resolution inventories of anthropogenic sources.The simulation is performed at a horizontal resolution of 7 km using a cubed-sphere horizontal grid with 72 vertical levels, extending up to to 0.01 hPa (~ 80 km). For user convenience, all data products are generated on two logically rectangular longitude-latitude grids: a full-resolution 0.0625o grid that approximately matches the native cubed-sphere resolution, and another 0.5o reduced-resolution grid. The majority of the full-resolution data products are instantaneous with some fields being time-averaged. The reduced-resolution datasets are mostly time-averaged, with some fields being instantaneous. Hourly data intervals are used for the reduced-resolution datasets, while 30-minute intervals are used for the full-resolution products. All full-resolution output is on the model\u2019s native 72-layer hybrid sigma-pressure vertical grid, while the reduced-resolution output is given on native vertical levels and on 48 pressure surfaces extending up to 0.02 hPa. Section 4 presents additional details on horizontal and vertical grids.", "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/C1634215803-NCCS.iso19115", "format": "ISO", "mediaType": "text/xml", "title": "Original Metadata"}, {"@type": "dcat:Distribution", "downloadURL": "https://portal.nccs.nasa.gov/cgi-lats4d/opendap.cgi?&path=%2FOSSE%2FG5NR%2FGanymed%2F7km", "format": "BIN", "mediaType": "application/octet-stream"}], "identifier": "/SDE/CMR_API/|C1634215803-NCCS", "keyword": ["earth-science-aerosols-atmosphere-dust-ash-smoke", "earth-science-air-quality-atmosphere-carbon-monoxide", "earth-science-air-quality-atmosphere-nitrogen-oxides", "earth-science-air-quality-atmosphere-sulfur-oxides", "earth-science-atmospheric-chemistry-atmosphere-carbon-and-hydrocarbon-compounds-carbon-dioxide", "earth-science-atmospheric-pressure-atmosphere-surface-pressure", "earth-science-atmospheric-radiation-atmosphere-longwave-radiation", "earth-science-atmospheric-temperature-atmosphere", "earth-science-atmospheric-winds-atmosphere", "earth-science-atmospheric-winds-atmosphere-wind-dynamics-convection", "earth-science-atmospheric-winds-atmosphere-wind-dynamics-turbulence", "earth-science-clouds-atmosphere-cloud-dynamics-moisture-flux", "earth-science-precipitation-atmosphere"], "license": "https://www.usa.gov/government-works", "modified": "2026-04-13", "programCode": ["026:000"], "publisher": {"@type": "org:Organization", "name": "NASA/GSFC/SED/ESD/GMAO;NASA/GSFC/SED/ESD/NCCS"}, "spatial": "[\"GEODETIC\",[{\"NorthBoundingCoordinate\":90.0,\"WestBoundingCoordinate\":180.0,\"EastBoundingCoordinate\":179.9375,\"SouthBoundingCoordinate\":90.0},{\"NorthBoundingCoordinate\":90.0,\"WestBoundingCoordinate\":180.0,\"EastBoundingCoordinate\":179.5,\"SouthBoundingCoordinate\":90.0}]], Atmosphere Layer, 72", "temporal": "2005-05-15/2007-06-16", "theme": ["Earth Science"], "title": "GEOS-5 Nature Run data"}
