		<abstract>At Centro de Previsão do Tempo e Estudos Climáticos 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.</abstract>
