Extraction of surface wind and current patterns from sar imagery

The capacity of synthetic aperture radar (SAR) to observe the sea surface and its potential for evaluating the marine studies, interpretation of atmospheric and oceanic phenomena make it a very useful tool for monitoring this study. In this paper the CMOD-4 and CMODIFR2 models are applied in the ext...
