The data are sorted into cycles that are approximately 11 days long and contain 280 pass files.  The instruments on Jason-1 make direct observations of the following quantities: altimeter range, significant wave height, ocean radar backscatter cross-section (a measure of wind speed), ionospheric electron content (derived by a simple formula), tropospheric water content, mean sea surface, and position relative to the GPS satellite constellation. The GDR contain all relevant corrections needed to calculate the sea surface height.", "distribution": [{"@type": "dcat:Distribution", "description": "Browse granule search results in Earthdata Search", "downloadURL": "https://search.earthdata.nasa.gov/search/granules?p=C2491731827-POCLOUD", "format": "HTML", "mediaType": "text/html", "title": "Download this dataset through Earthdata Search"}, {"@type": "dcat:Distribution", "description": "Data Use and Citation Policy", "downloadURL": "https://podaac.jpl.nasa.gov/CitingPODAAC", "format": "HTML", "mediaType": "text/html", "title": "View this dataset's data citation policy"}, {"@type": "dcat:Distribution", "description": "Generic data readers", "downloadURL": "https://github.com/podaac/data-readers", "format": "HTML", "mediaType": "text/html", "title": "View this dataset's data recipes"}, {"@type": "dcat:Distribution", "description": "HTTPS endpoint for data browse and download", "downloadURL": "https://cmr.earthdata.nasa.gov/virtual-directory/collections/C2491731827-POCLOUD", "format": "HTML", "mediaType": "text/html", "title": "Download this dataset through a directory map"}, {"@type": "dcat:Distribution", "description": "Jason-1 User Guide", "downloadURL": "https://archive.podaac.earthdata.nasa.gov/podaac-ops-cumulus-docs/jason1/open/L2/docs/Handbook_Jason-1_v5.1_April2016.pdf", "format": "PDF", "mediaType": "application/pdf", "title": "View this dataset's user's guide"}, {"@type": "dcat:Distribution", "description": "Jason-1 cycle start list", "downloadURL": "https://archive.podaac.earthdata.nasa.gov/podaac-ops-cumulus-docs/jason1/open/L2/docs/j1_cyclelist.txt", "format": "HTML", "mediaType": "text/html", "title": "View documentation related to this dataset"}, {"@type": "dcat:Distribution", "description": "Jason-1 maneuvers", "downloadURL": "https://archive.podaac.earthdata.nasa.gov/podaac-ops-cumulus-docs/jason1/open/L2/docs/j1_maneuver.txt", "format": "HTML", "mediaType": "text/html", "title": "View this dataset's documented anomalies"}, {"@type": "dcat:Distribution", "description": "Jason-1 safeholds and known data outages", "downloadURL": "https://archive.podaac.earthdata.nasa.gov/podaac-ops-cumulus-docs/jason1/open/L2/docs/j1_safehold.txt", "format": "HTML", "mediaType": "text/html", "title": "View this dataset's documented anomalies"}, {"@type": "dcat:Distribution", "description": "PO.DAAC Drive", "downloadURL": "https://archive.podaac.earthdata.nasa.gov/podaac-ops-cumulus-docs/jason1/open/L2/gdr_netcdf_e_geodetic/docs/Handbook_Jason-1_v5.1_April2016.pdf", "format": "HTML", "mediaType": "text/html", "title": "Download this dataset"}, {"@type": "dcat:Distribution", "description": "Thumbnail", "downloadURL": "https://podaac.jpl.nasa.gov/Podaac/thumbnails/JASON-1_L2_OST_GPN_E_GEODETIC.jpg", "format": "JPEG", "mediaType": "image/jpeg", "title": "Get a related visualization"}], "identifier": "C2491731827-POCLOUD", "issued": "2014-03-17", "keyword": ["earth-science", "ocean-waves", "oceans", "sea-surface-topography"], "landingPage": "https://cmr.earthdata.nasa.gov:443/search/concepts/C2491731827-POCLOUD.html", "language": ["en-US"], "modified": "2025-04-23", "programCode": ["026:001"], "publisher": {"@type": "org:Organization", "name": "NASA/JPL/PODAAC"}, "spatial": "-180.0 -66.15 180.0 66.15", "temporal": "2012-05-07T16:00:00Z/2013-06-21T00:56:55Z", "theme": ["JASON-1", "geospatial"], "title": "Jason-1 GDR version E NetCDF Geodetic"}
