Sea surface emissivity observations at L-band: first preliminary results of the WInd and Salinity Experiment WISE-2000

This paper presents the first measurements processed from the data acquired with the L-band AUtomatic RAdiometer (LAURA) during the WInd and Salinity Experiment (WISE-2000). Experimental results are compared to a sea surface emissivity model developed by the Polytechnic University of Catalonia (UPC). The sensitivity of the brightness temperatures at vertical and horizontal polarizations to wind speed are discussed, as well as the weak azimuthal signature found.
