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: Level-2 Geophysical Data Records (GDR) from the Jason-2/Ocean Surface Topography Mission (OSTM)
Abstract: This accession contains the data descriptions from the Jason-2/Ocean Surface Topography Mission (OSTM), which is served through the NOAA/NESDIS Comprehensive Large Array-data Stewardship System (CLASS): http://www.nsof.class.noaa.gov/saa/products/welcome

The level 2 geophysical data records derived from instruments aboard the JASON-2 satellite are available as 3 datatypes: Operational Geophysical Data Records (OGDR), Interim Geophysical Data Records (IGDR) and final Geophysical Data Records (GDR). The OGDRs are near-real-time records and are generated every 3-5 hours. The IGDRs are based on preliminary DORIS ephemeris, analyzed meteorological grids, and preliminary auxiliary data files. They have a data latency of 1 - 2 days. The S-IGDR is a superset of the IGDR, containing the original radar echo "waveform" data. The GDRs are based on final high-precision DORIS (perhaps combined with GPS) ephemeris, final meteorological grids, ancillary and auxiliary data files. S-GDR is a superset of the GDR, containing the waveform data. They are generated every 10 days. Sea Surface Height Anomaly (SSHA) files are available for IGDR and GDR. All files are available in NetCDF format and the OGDR is also available in BUFR format.
Other data/products associated with OSTM/Jason-2 are also provided through CLASS. They are: ancillary and auxiliary data files used to generate Level-2 products, user science documentation and other project documentation as required for complete understanding of the science data products, quality reports from the near real-time altimetry validation system (NRTAVS), orbit information of JASON-2 satellite, software and telemetry data.
