Jason-1 GDR version E NetCDF Geodetic

Published by NASA/JPL/PODAAC;NASA/JPL/TPJOT | National Aeronautics and Space Administration | Catalog Last Checked: November 11, 2026 at 12:24 AM | Dataset Last Updated: November 05, 2026
The Jason-1 Geophysical Data Records (GDR) Geodetic Mission contain full accuracy altimeter data, with a high precision orbit, provided approximately 35 days after data collection. The data are sorted into cycles that are approximately 11 days long and contain 280 pass files. The instruments on Jason-1 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, mean sea surface, and position relative to the GPS satellite constellation. The GDR contain all relevant corrections needed to calculate the sea surface height.
