The Ocean Archive System searches our original datasets as they were submitted to us, not individual points or profiles. If you want to search and retrieve ocean profiles in a common format, or objectively analyzed fields, your better option may be to use one of our project applications. See: Access Data

| Title: | Geosat Exact Repeat Mission Waveform Data Records (WDR) (NCEI Accession 0061150) |
| Abstract: | This dataset contains waveform data records (WDRs) from the US Navy Geodetic Satellite (GEOSAT) Exact Repeat Mission (ERM) for the time period of November 08, 1986 through December 30, 1989. Parameters include: time, orbit, latitude/longitude, and sea surface height. Corrections to the data include: sea level, wind and wave data, tides, dry and wet troposphere, ionosphere, height bias, altimeter crossover differences, altimeter sea surface measurement, and spacecraft orientation. These data were submitted by the U.S. Navy via NOAA Office of Research and Applications' Laboratory for Satellite Altimetry (LSA), which was previously National Oceanic Service Satellite Altimeter Group. The US Navy Geosat radar altimeter mission lasted for nearly 5 years (March 1985 to January 1990) and collected approximately 750 million measurements of sea level, wave height, and wind speed over the global oceans. During the Geodetic Mission (March 1985 to September 1986), the satellite did not repeat its ground track for the duration of the mission. The orbit of the satellite was changed in late 1986 to begin the Exact Repeat Mission (ERM) which lasted from October 1, 1986 until the satellite quit functioning in January 1990. During the ERM, the satellite repeated its ground track every 17 days. Data were initially processed by the Johns Hopkins University Applied Physics Laboratory in Laurel, MD in coordination with the NOAA/NOS Satellite Altimeter Group. Data products were transferred to the NOAA National Oceanographic Data Center (NODC) for distribution. Data products are archived at the NODC. |
