Abstract

An advanced synergetic approach for analysis of SAR and optical scanner data focusing on study of meso- scale ocean dynamics and its surface signatures is presented. MODIS and ASAR WS data for Agulhas current area are chosen for this study. We discuss how “standard” MODIS-SST and SAR-wind products can be supplemented with additional data on quasi-geostrophic and ageostrophic currents fields and their manifestation on the sea surface in form of the mean square slope (MSS) contrasts and SAR “roughness”. It is shown that zones of the surface current convergence/divergence are coincided with current vorticity gradients and well “visible” on the sea surface as MSS and SAR roughness anomalies.
