Sentinel-6A MF Jason-CS L1A P4 Altimeter High Resolution (HR) STC Intermediate Outputs with Instrument Calibrations

Published by NASA/JPL/PODAAC | National Aeronautics and Space Administration | Catalog Last Checked: September 23, 2026 at 12:58 AM | Dataset Last Updated: September 15, 2026
Provides L1A high resolution (HR) short time critical (STC; 36-hour latency) altimetry intermediate outputs from the Poseidon-4 SAR altimeter on the Sentinel-6A Michael Freilich spacecraft, which are geo-located bursts of Ku-band echoes (at ~140 Hz) with all instrument calibrations applied and full rate complex waveforms for delay/Doppler or HR processing. The S6A STC product is analogous to the Jason-3 IGDR product.
