These mono-mission products contain calibrated (relative to buoys) along-track significant wave height (SWH), a validity flag and the applied bias correction.

They are processed by the Sentinel-3 L2P/L3 Marine Altimetry Service (CNES/CLS), in the frame of a EUMETSAT contract, part of the Copernicus Programme funded by the European Union.
