This paper describes an automatic procedure to download and process SAR images in the coastal areas, in order to get the wind field. The images processed are the Erivisat ASARWide Swath. The methodology to retrieve b the wind fields is based on the 2-D Continuous Wavelet Transform, developed in Zecchetto and De Biasio {[}2002] and applied in Zecchetto and De Biasio {[}2008]. About three images per day are processed since May 2008. Co-location of the SAR derived winds with those provided by QulkSCAT and Metop will permit to validate the methodology over a large variety of atmospheric regimes. Once validation will be accomplished, the procedure described in this paper will be used to derive the wind fields for coastal meteorology applications.

About three images per day are processed since May 2008.
