NOAA worked together with the Naval Oceanographic Office to process the altimeter data and provides the NOAA version of the Geophysical Data Record (GDR) to the scientific research community. The GDR is generated from GFO Sensor Data Records (SDRs), precise laser orbit ephemerides (POE) provided by NASA Goddard Space Flight Center and Raytheon ITSS, environmental corrections, and ancillary geophysical variables. POE are produced at NASA Goddard Space Flight Center (GSFC) within 3-4 weeks. They have an expected radial accuracy of 5 cm RMS (Root Mean Squared) over the six day arc. The Sensor Data Record (SDR) provides time tagged altimeter and radiometer data. GFO Operational Orbit Determination Data (OODD) was generated by the United States Naval Satellite Operations Center (NAVSOC). Housekeeping telemetry, radiometer and altimeter calibration and full waveform data (when available) for the altimeter calibration are also available. This dataset is available to the public for a wide variety of uses including scientific research and analysis. completed historicalArchive NOAA National Centers for Environmental Information ncei.info@noaa.gov https://www.ncei.noaa.gov/contact HTTPS NCEI Contact Information Information for contacts at NCEI. information pointOfContact asNeeded https://www.ncei.noaa.gov/access/metadata/landing-page/bin/gfx?id=gov.noaa.nodc:GEOSAT-GFO Preview graphic PNG 0085958 0085959 0085960 0085961 0085962 NCEI ACCESSION NUMBER 2012-02-25 publication ALTIMETRY - CROSSOVER DIFFERENCES ALTIMETRY - SEA SURFACE HEIGHT LATITUDE LONGITUDE SEA HEIGHT SEA LEVEL SEA SURFACE TOPOGRAPHY WAVE HEIGHT theme NODC DATA TYPES THESAURUS satellite sensor - altimeter instrument NODC INSTRUMENT TYPES THESAURUS derived products meteorological physical satellite data surface measurements theme NODC OBSERVATION TYPES THESAURUS GFO (GEOSAT FOLLOWON, GEOSat Follow-on, Geosat Follow On) platform NODC PLATFORM NAMES THESAURUS NASA Goddard Space Flight Center US Navy Naval Oceanographic Office dataCentre NODC COLLECTING INSTITUTION NAMES THESAURUS NOAA Center for Satellite Applications and Research dataCentre NODC SUBMITTING INSTITUTION NAMES THESAURUS World-Wide Distribution place NODC SEA AREA NAMES THESAURUS oceanography theme WMO_CategoryCode 2012-09-15 publication DOC/NOAA/NESDIS/NODC > National Oceanographic Data Center, NESDIS, NOAA, U.S. Department of Commerce DOC/NOAA/NESDIS/STAR > Center for Satellite Applications and Research, NESDIS, NOAA, U.S. Department of Commerce DOD/USNAVY/NAVOCEANO > Naval Oceanographic Office, U.S. Navy, U.S. Department of Defense dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2026 revision 24 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) Greenbelt MD https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords HTTPS GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.
