Jason-1 GDR SSHA version E NetCDF Geodetic
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/j1gpr-ncg0e
These Sea Surface Height Anomalies (SSHA) are derived from the Jason-1 Geophysical Data Record (GDR) Geodetic Mission.
Description
Jason-1 is an altimetric mission whose instruments 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, and position relative to the GPS satellite constellation.
Using the various parameter the SSHA can be calculated and are provided in this dataset. The data are in NetCDF format.
