Estimating the Circulation and Climate of the Ocean (ECCO) ocean and sea-ice state estimates are dynamically and kinematically-consistent reconstructions of the three-dimensional time-evolving ocean, sea-ice, and surface atmospheric states. ECCO V4r4 is a free-running solution of the 1-degree global configuration of the MIT general circulation model (MITgcm) that has been fit to observations in a least-squares sense. Observational data constraints used in V4r4 include sea surface height and model sea level anomaly (SSH) from satellite altimeters [ERS-1/2, TOPEX/Poseidon, GFO, ENVISAT, Jason-1,2,3, CryoSat-2, and SARAL/AltiKa]; sea surface temperature (SST) from satellite radiometers [AVHRR], sea surface salinity (SSS) from the Aquarius satellite radiometer/scatterometer, ocean bottom pressure (OBP) from the GRACE satellite gravimeter; sea ice concentration from satellite radiometers [SSM/I and SSMIS], and in-situ ocean temperature and salinity measured with conductivity-temperature-depth (CTD) sensors and expendable bathythermographs (XBTs) from several programs [e.g., WOCE, GO-SHIP, Argo, and others] and platforms [e.g., research vessels, gliders, moorings, ice-tethered profilers, and instrumented pinnipeds]. V4r4 covers the period 1992-01-01T12:00:00 to 2018-01-01T00:00:00.\", \"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/C1991543813-POCLOUD.iso19115\", \"format\": \"ISO\", \"mediaType\": \"text/xml\", \"title\": \"Original Metadata\"}, {\"@type\": \"dcat:Distribution\", \"downloadURL\": \"https://archive.podaac.earthdata.nasa.gov/podaac-ops-cumulus-docs/web-misc/ecco/docs/v4r4_overview_plots.pdf\", \"format\": \"PDF\", \"mediaType\": \"application/pdf\"}, {\"@type\": \"dcat:Distribution\", \"downloadURL\": \"https://archive.podaac.earthdata.nasa.gov/podaac-ops-cumulus-docs/web-misc/ecco/docs/v4r4_reproduction_howto.pdf\", \"format\": \"PDF\", \"mediaType\": \"application/pdf\"}, {\"@type\": \"dcat:Distribution\", \"downloadURL\": \"https://archive.podaac.earthdata.nasa.gov/podaac-ops-cumulus-docs/web-misc/ecco/docs/v4r4_synopsis.pdf\", \"format\": \"PDF\", \"mediaType\": \"application/pdf\"}, {\"@type\": \"dcat:Distribution\", \"downloadURL\": \"https://archive.podaac.earthdata.nasa.gov/podaac-ops-cumulus-docs/web-misc/ecco/docs/v4r4_user_guide.pdf\", \"format\": \"PDF\", \"mediaType\": \"application/pdf\"}, {\"@type\": \"dcat:Distribution\", \"downloadURL\": \"https://cmr.earthdata.nasa.gov/virtual-directory/collections/C1991543813-POCLOUD/temporal\", \"format\": \"BIN\", \"mediaType\": \"application/octet-stream\"}, {\"@type\": \"dcat:Distribution\", \"downloadURL\": \"https://doi.org/10.5067/ECL5M-SSH44\", \"format\": \"HTML\", \"mediaType\": \"text/html\"}, {\"@type\": \"dcat:Distribution\", \"downloadURL\": \"https://dspace.mit.edu/handle/1721.1/110380\", \"format\": \"BIN\", \"mediaType\": \"application/octet-stream\"}, {\"@type\": \"dcat:Distribution\", \"downloadURL\": \"https://ecco-v4-python-tutorial.readthedocs.io/\", \"format\": \"BIN\", \"mediaType\": \"application/octet-stream\"}, {\"@type\": \"dcat:Distribution\", \"downloadURL\": \"https://github.com/ECCO-GROUP/\", \"format\": \"BIN\", \"mediaType\": \"application/octet-stream\"}, {\"@type\": \"dcat:Distribution\", \"downloadURL\": \"https://github.com/ECCO-GROUP/ECCO-v4-Configurations/tree/master/ECCOv4%20Release%204\", \"format\": \"BIN\", \"mediaType\": \"application/octet-stream\"}, {\"@type\": \"dcat:Distribution\", \"downloadURL\": \"https://github.com/podaac/data-readers\", \"format\": \"BIN\", \"mediaType\": \"application/octet-stream\"}, {\"@type\": \"dcat:Distribution\", \"downloadURL\": \"https://podaac.jpl.nasa.gov/Podaac/thumbnails/ECCO_L4_SSH_LLC0090GRID_MONTHLY_V4R4.jpg\", \"format\": \"JPEG\", \"mediaType\": \"image/jpeg\"}, {\"@type\": \"dcat:Distribution\", \"downloadURL\": \"https://podaac.jpl.nasa.gov/ecco\", \"format\": \"BIN\", \"mediaType\": \"application/octet-stream\"}, {\"@type\": \"dcat:Distribution\", \"downloadURL\": \"https://search.earthdata.nasa.gov/search/granules?p=C1991543813-POCLOUD\", \"format\": \"BIN\", \"mediaType\": \"application/octet-stream\"}, {\"@type\": \"dcat:Distribution\", \"downloadURL\": \"https://www.ecco-group.org\", \"format\": \"BIN\", \"mediaType\": \"application/octet-stream\"}], \"identifier\": \"10.5067/ECL5M-SSH44\", \"keyword\": [\"earth-science-sea-surface-topography-oceans-sea-surface-height\", \"earth-science-services-earth-science-reanalyses-assimilation-models-models\"], \"license\": \"https://www.usa.gov/government-works\", \"modified\": \"2026-03-16\", \"programCode\": [\"026:000\"], \"publisher\": {\"@type\": \"org:Organization\", \"name\": \"NASA/JPL/PODAAC\"}, \"spatial\": \"[\\\"CARTESIAN\\\",[{\\\"NorthBoundingCoordinate\\\":90.0,\\\"WestBoundingCoordinate\\\":-180.0,\\\"EastBoundingCoordinate\\\":180.0,\\\"SouthBoundingCoordinate\\\":-90.0}]]\", \"temporal\": \"1992-01-01/2018-01-01\", \"theme\": [\"Earth Science\"], \"title\": \"ECCO Sea Surface Height - Monthly Mean llc90 Grid (Version 4 Release 4)\"}","source_transform":null,"status":"success"}
