%X Surface winds are crucial for accurately modeling,the surface circulation in the coastal ocean. In,the present work, high-frequency radar surface currents,are assimilated using an ensemble scheme which aims,to obtain improved surface winds taking into account,European Centre for Medium-Range Weather Forecasts,winds as a first guess and surface current measurements.,The objective of this study is to show that,wind forcing can be improved using an approach similar,to parameter estimation in ensemble data assimilation.,Like variational assimilation schemes, the method provides,an improved wind field based on surface current,measurements. However, the technique does not require,an adjoint, and it is thus easier to implement.,In addition, it does not rely on a linearization of the,model dynamics. The method is validated directly by,comparing the analyzed wind speed to independent,in situ measurements and indirectly by assessing the,impact of the corrected winds on model sea surface,temperature (SST) relative to satellite SST.
