GLOBAL VALIDATION OF SENTINEL-3 WIND WAVE PRODUCTS

摘要

Wind and wave data from the radar altimeter instruments are of considerable importance for numerical weather prediction and in particular for the ocean waves. SRAL, which is the altimeter on-board the newly launched Copernicus Sentinel-3 satellite, implements the Doppler shift (or SAR) altimetry to provide this type of data with a superior quality compared to conventional altimeters. The results obtained from the limited SRAL data set that was made available a couple of weeks ago proved the very high quality of such data. The wave height data will be assimilated in the ECMWF IFS model after they become operationally available.
