Abstract :
ERS-1 SAR image expressions of mesoscale coastal ocean circulation features are examined. The dominating geophysical quantities and processes that are participating in the formation of the image expression are discussed. An attempt to characterise dynamics of the current features is carried out employing a SAR simulation model. Preliminary results suggest that systematic combination of simulation models and SAR images can lead to better quantitative interpretation of SAR images
