             abstract = "Past publications have shown that Synthetic Aperture Radar, used 
                         in combination with thermal images may overcome problems related 
                         with extensive cloud cover, allowing a proper representation of 
                         oceanic features, such as the Brazil Current (BC) front. However, 
                         some SAR images of the Southeastern Brazilian Coast show no signs 
                         of the surface signature of the BC front. In this work, 
                         simulations were conducted using the Ocean SAR Image Numerical 
                         Simulator Model - M4S, in order to understand the mechanisms which 
                         allow the visualization of the BC thermal front in SAR images 
                         depicting the offshore zone off Santos Basin. As a first step, an 
                         ASAR/ENVISAT image (C-band, VV polarization) depicting the BC 
                         thermal front at the area was acquired of the INPE base data. The 
                         wind velocity field, which was used as a mandatory input file of 
                         the M4S model, was generated based on a Cross-Calibrated 
                         Multi-Platform (CCMP) product. Analysis comprised two simulations: 
                         in the first one only the effects of the aerodynamic modulation on 
                         the sigma zero values at the thermal front region was considered; 
                         in the second the effects of both aerodynamic and hydrodynamic 
                         modulations were considered. Results showed a good agreement 
                         between real and simulated SAR image signatures when the 
                         hydrodynamic (via surface currents divergence of -5x10-4 s-1 and 
                         shear of -8x10-4 s-1) effects were considered, in combination with 
                         the aerodynamic modulation, and when the relaxation rate was 
                         reduced by 88%.",
