Description

Provides L1B low resolution (LR) short time critical (STC; 36-hour latency) altimetry data from the Poseidon-4 SAR altimeter on the Sentinel-6B spacecraft which include the geolocated, fully-calibrated pulse-limited LR power echoes. The S6B STC product is analogous to the Jason-3 IGDR product.
