C‐band High and Extreme‐Force Speeds (CHEFS) ‐ Final Report

EUMETSAT supported the CHEFS study, which provided resources to KNMI, ICM and IFREMER to lead and progress on the ocean winds community issue of an in‐situ reference for satellite and model calibration of extreme winds. Such study is only possible with access to uniformly reprocessed wind data sets which were obtained from NOAA/NESDIS/STAR OSWT dropsondes and SFMR, ICOADS buoys, ECMWF buoy archive and ERA5 winds, ESA Sentinel‐1 SAR and RadarSat SAR VV and VH data
