The global ocean simulation is based on the MIT general circulation model (MITgcm) with Lat-Lon-Cap grid (LLC) layout and 1/48-degree (2km at equator) nominal horizontal resolution. This simulation is often referred to as LLC4320 in the community and existing publications. The simulation has 90 vertical levels, with about 1-m vertical resolution at the surface and 30 m down to 500 m, for optimized resolution of the upper-ocean processes. The model has zero parameterized horizontal diffusivity. In the vertical direction, the K-Profile Parameterization (KPP) is used for boundary layer turbulent mixing. It is spun up progressively from the lower resolution MITgcm simulation from the Estimating the Circulation & Climate of the Ocean (ECCO), and forced by the 6-hourly ERA-Interim atmosphere reanalysis ( https://www.ecmwf.int/en/forecasts/datasets/reanalysis-datasets/era-interim ). A synthetic surface pressure field consisting of the 16 most dominant tidal constituents is used to dynamically mimic the tidal forcing. The dataset provides hourly oceanographic variables at native grid. Three-dimensional variables include temperature, salinity, and velocity. Two-dimensional variables include sea level anomaly, ocean mixed layer thickness, bottom pressure anomaly, net freshwater flux, net heat flux, shortwave radiative flux, net salt flux, and ocean surface stress.", "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/C2006849571-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/SWOT/Pre-SWOT_LLC4320/README", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://archive.podaac.earthdata.nasa.gov/podaac-ops-cumulus-docs/web-misc/SWOT/Pre-SWOT_LLC4320/preswot_llc4320_user_guide.pdf", "format": "PDF", "mediaType": "application/pdf"}, {"@type": "dcat:Distribution", "downloadURL": "https://cmr.earthdata.nasa.gov/virtual-directory/collections/C2006849571-POCLOUD", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://doi.org/10.5067/PRESW-NCJ10", "format": "HTML", "mediaType": "text/html"}, {"@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/MEaSUREs-SSH", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://podaac.jpl.nasa.gov/Podaac/thumbnails/MITgcm_LLC4320_Pre-SWOT_JPL_L4_NewCaledonia_v1.0.jpg", "format": "JPEG", "mediaType": "image/jpeg"}, {"@type": "dcat:Distribution", "downloadURL": "https://podaac.jpl.nasa.gov/SWOT", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://search.earthdata.nasa.gov/search/granules?p=C2006849571-POCLOUD", "format": "BIN", "mediaType": "application/octet-stream"}], "identifier": "10.5067/PRESW-NCJ10", "keyword": ["earth-science-ocean-circulation-oceans-fresh-water-flux", "earth-science-ocean-circulation-oceans-ocean-currents", "earth-science-ocean-heat-budget-oceans-heat-flux", "earth-science-ocean-temperature-oceans-potential-temperature", "earth-science-salinity-density-oceans-salinity"], "license": "https://www.usa.gov/government-works", "modified": "2026-04-21", "programCode": ["026:000"], "publisher": {"@type": "org:Organization", "name": "NASA/JPL/PODAAC"}, "spatial": "[\"CARTESIAN\",[{\"NorthBoundingCoordinate\":-22.0,\"WestBoundingCoordinate\":166.0,\"EastBoundingCoordinate\":171.0,\"SouthBoundingCoordinate\":-26.0}]], Maximum Depth;Minimum Depth, 6134.5;0", "temporal": "2011-09-13/2012-11-15", "theme": ["Earth Science"], "title": "New Caledonia Pre-SWOT Level-4 Hourly MITgcm LLC4320 Native Grid 2km Oceanographic Dataset Version 1.0"}
