It contains Sea Surface Height (SSH), Sea Surface Height Anomalies (SSHA) and Significant Wave Height (SWH), along with 1 Hz Ku-band measurements processed from L1B altimetry including the range, orbital altitude, time, and water vapour. It also includes altimetry corrections, significant wave height and wind-speed from the AMR-C. This release is reduced to exclude the 20 Hz observations that are included in the standard product. The S6A NRT product is analogous to the Jason-3 OGDR product.", "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/C2006849488-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/C2006849488-POCLOUD", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://doi.org/10.5067/PRESW-NPJ10", "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://github.com/podaac/data-subscriber", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://opendap.earthdata.nasa.gov", "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_NWPacific_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=C2006849488-POCLOUD", "format": "BIN", "mediaType": "application/octet-stream"}], "identifier": "10.5067/S6AP4-2HRNR", "keyword": ["earth-science-ocean-waves-oceans-significant-wave-height", "earth-science-sea-surface-topography-oceans-sea-surface-height"], "license": "https://www.usa.gov/government-works", "modified": "2026-09-08", "programCode": ["026:000"], "publisher": {"@type": "org:Organization", "name": "NASA/JPL/PODAAC"}, "spatial": "[\"CARTESIAN\", [{\"NorthBoundingCoordinate\": 66.15, \"WestBoundingCoordinate\": -180.0, \"EastBoundingCoordinate\": 180.0, \"SouthBoundingCoordinate\": -66.15}]]", "theme": ["Earth Science"], "title": "Sentinel-6A MF Jason-CS L2 P4 Altimeter High Resolution (HR) NRT Reduced Ocean Surface Topography"}
