Monomission altimeter product, available for several missions in Near-Real Time (NRT), Short Critical Time (SCT) and Non Time Critical Time (NTC)

Significant Wave Height (SWH) monomission along-track altimeter satellite product available for Sentinel-3A, Sentinel-3B and Sentinel-6 Michael Freilich missions in Near-Real-Time. SWH values are computed from the High Resolution Mode, also known as Synthetic Aperture Radar mode (SAR) and are calibrated relative to buoys. A validity flag and the applied correction are also provided. Since April 2021, a new variable is included in the files : wind speed, computed by Gourrion (2002) algorithm using Collard (2005) table with PLRM sigma0 and SWH. Moreover, the values are cross-calibrated with Jason-3 standard F wind speed.

Wave products from french SWIM instrument (height, direction, wavelength) and wind products from chinese SCAT scatterometer (wind speed and direction) on CFOSAT mission. Some meteorological variables sampled at the location of SWIM acquisitions are also distributed in dedicated files.
