This work shows the analysis of the convection 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.
