Ocean wave spectrum and radar cross-section analysis from coincident ENVISAT ASAR observations and airborne polarimetric radar measurements performed during the VALPARESO experiment

We present results obtained from the Valpareso campaign dedicated to the validation of the ASAR ENVISAT ocean wave products. Data from the ASAR image mode are analyzed in terms of wave spectra, radar cross-section and wind speed and compared to ocean wave spectra and radar-crosssection profiles obtained from the airborne polarimetric radar STORM, to in situ measurements from a buoy and to data from the wave prediction model WAM.
