Sentinel-6A MF Jason-CS L2P P4 Altimeter Low Resolution (LR) NTC Ocean Surface Topography F08

Published by NASA/JPL/PODAAC | National Aeronautics and Space Administration | Catalog Last Checked: June 25, 2026 at 01:54 PM | Dataset Last Updated: June 23, 2026
Provides L2P low resolution (LR) non-time critical (NTC; 60-day latency) altimetry from the Poseidon-4 SAR altimeter on the Sentinel-6A Michael Freilich spacecraft, and contains L2-equivalent geophysical sea-state data at a slightly different latency than the other L2 NRT products. The sea-state data were derived from L1B altimetry, and include range, orbital altitude, time, and water vapour. Environmental and geophysical corrections, significant wave height, and wind-speed information are supplied by the AMR-C. The S6A NTC product is analogous to the Jason-3 GDR product.
