Jason-1 GDR SSHA version E NetCDF Geodetic

Published by NASA/JPL/PODAAC | National Aeronautics and Space Administration | Catalog Last Checked: November 11, 2026 at 12:41 AM | Dataset Last Updated: March 31, 2025
These Sea Surface Height Anomalies (SSHA) are derived from the Jason-1 Geophysical Data Record (GDR) Geodetic Mission. 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.
