Sea surface current retrievals using ASAR WVW acquisitions

In this paper, we present an algorithm aimed at extracting ocean surface current information from SAR acquisitions based on wind information. The acquisitions used to test this algorithm are the Wave Mode Ocean Wave Spectra products, called WVW acquisitions, from ASAR, the C-Band SAR onboard ENVISAT. Parts of this method have already been tested with monthly means. We show here using buoy measurements that this method is able to yield the radial component of sea surface currents. These results will be used as a complement to sea surface current data gathering.
