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: | Crossover difference data records (XDR) from GEOSAT Geodetic Mission (GM) and Exact Repeat Mission (ERM) data from 01 January 1985 to 31 December 1989 (NODC Accession 9000068) |
| Abstract: | Crossover difference data records (XDRs) from the GEOSAT Geodetic Mission (GM) and Exact Repeat Mission (ERM) for the time period of January 01, 1985 to December 31, 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 National Oceanic Service.
The US Navy Geosat (Geodetic Satellite) 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 (1986 to 1987), the satellite did not repeat its ground track for the duration of the mission. The orbit of the satellite was changed in early 1988 to begin the Exact Repeat Mission (ERM) which lasted from 1988 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. |

The set of two tapes (NODC working tape #s D03236, and D03237, NODC reference number L00950) contain Crossover Difference records (xdr s) from the Northeast Atlantic region. Additional Geosat data from other ocean regions is filed under NODC accession # 9000068, NODC reference #s L00950-L00959. Data for each region are held on two magnetic tapes per region, with each set of two tapes filed under a single reference number.

TWENTY TAPES OF GEOSAT SEQUENTIAL CROSSOVER DATA Since data was offline on January 25, 2005 when this abstract was written. Please check the final format in which the data is available and accordingly change the abstract before uploading. Note: Metadata for this accession were extracted from a legacy database maintained by the U.S. National Oceanographic Data Center (NODC). The design of the database did not exactly reflect the FGDC Content Standard for Digital Geospatial Metadata (CSDGM). Principal Investigator (PI) and organization contact information accurately represents all available information from the legacy database at the time that this description was created. However, proper attribution of a PI to a specific institution or the role (submitting or collecting) taken by an institution may not be correct due to inexact mapping between fields in the legacy database and the CSDGM. Due to this uncertainty, the contact information was initially recorded in the Supplemental Information element of the CSDGM description. To develop more accurate metadata, the NODC reviews metadata for all accessions on an ongoing basis.
