                         CPTEC, we are implement the System Assimilation for the Global 
                         Model CPTEC/INPE called Physical-space Statistical Analysis System 
                         (PSAS) development by Data Assimilation Office DAO at NASA. The 
                         PSAS is ready to assimilate conventional data and non-conventional 
                         data; for the South Hemisphere the conventional data is poor, then 
                         the non-conventional data coming from satellite is a alternative 
                         to improve the analysis, This paper shows some results about the 
                         inclusion of the data satellite in the PSAS to obtain the initial 
                         conditions for the Global Model CPTEC/INPE at CPTEC. We compare 
                         first, the number of observations for each 6 hours when is 
                         obtained the initial conditions, the number of observations 
                         including data satellite, TOVS is almost three times the number of 
                         conventional data. The fields analysis of virtual temperature, 
                         specific humidity and winds for all the levels in the vertical 
                         atmosphere, shows differences between analysis fields with TOVS 
                         and without TOVS, mostly in the virtual temperature fields, this 
                         difference is because the PSAS assimilate the data satellite like 
                         virtual temperature. Finally, the fields analysis including TOVS 
                         is more close than the fields analysis without TOVS to fields 
                         analysis of NCEP.",
