                         explicitly resolved by BRAMS model, done as part of the CHUVA 
                         project, where the resolved clouds and the ones present on real 
                         satellite images were compared. Radiances at infrared and 
                         microwave channels of GOES-Imager and SSMI-S were simulated using 
                         the radiative transfe rmodel RTTOV and then compared to its 
                         respective real images. The atmospheric profiles simulated by 
                         BRAMS were used as state vector to RTTOV. This comparison verified 
                         if the BRAMS was capable to reproduce the general behavior of the 
                         convection, despite erros in the geographic placement of 
                         individual clouds. For CHUVA project, seven field experiments over 
                         different locations of Brazil, dominated by distinct climate 
                         patterns, were done to study the various preciptation regimes over 
                         the country. The metodology presented here was applied only on the 
                         Vale do Paraiba experiment and the results shows that this 
                         metodology can be applied to the other field experiments of the 
                         CHUVA project.",
