Description

Provides L3 low resolution (LR) non-time critical (NTC; 60-day latency) altimetry from the Poseidon-4 SAR altimeter on the Sentinel-6A Michael Freilich spacecraft, which includes the unfiltered geophysical sea-state parameters that have been spatially and/or temporally resampled or corrected, including potential averaging over multiple orbits. The S6A NTC product is analogous to the Jason-3 GDR product.
