%X The purpose of this work was to analyse the performance of the AIRS/AQUA sounding system (physical- statistical retrieval code) and of the MODIS/AQUA (statistical retrieval code) to recover atmospheric profiles of temperature and moisture over Natal (northeast region of Brasil) during the SHADOZ (Southern Hemisphere ADditional OZonesondes) campaign along 2004 and 2005. The atmospheric profiles retrieved by both inversion models were compared with the collocated radiossonde data ("ground truth") of the campaing, considering satellite retrievals within a 100 km radius around the sounding site. The bias and the root mean square error (RMS) of deviations were assessed for the whole avaible data of the campaing. The results showed that temperature profiles retrieved from AIRS/AQUA has a bias lower than 1k for pressure levels below 500 hPa, while the MODIS profiles has a bias about -2k, near the ground level. In the troposphere the AIRS soundings showed lower root mean square error (about 1.5k) compared with MODIS retrievals (until 3.5k near the ground level) for all pressure levels below 200 hPa. Concerning moisture profiles, the results showed that MODIS and AIRS/AMSU profiles have bias about -2 to -4 g/kg for pressure levels below 800 hPa, respectively. In addition, both of them had similar RMS in the troposphere reaching 2 g/kg near the ground level.
