This refinement originates from a better matching of the surface current estimated by the wind in Figure 10G and the surface current derived by the DCA in Figure 10B with respect to Figure 10H. Figure 6: Results related to the acquisition of 17/11/2004.The image is divided as follow: (**A**) is the \(o^{0}\), (**B**) is the estimated Doppler Anomaly maps of the marine area converted into the line-of-sight component of the sea surface velocity; (**C**) is the wind direction obtained from the CMOD model; (**D**) is the wind direction obtained from the WRF-ARW model; (**E**) is the wind speed relative to the CMOD model; (**F**) is the wind speed relative to the WRF-ARW model; (**G**) and (**H**) is the surface radial velocity due to the wind component, evaluated as descried in Section 4, for the CMOD model and for the WRF-ARW model, respectively.

In order to a comprehensive interpretation of the results with respect to the circulation currents, the surface current in the area has been investigated by using an oceanographic numerical model for the date of 22 September 2010. Specifically, a state-of-the-art ocean model (SHYFEM, [43]) was applied to compute the circulation patterns in the area during the whole of September 2010.
