                         water obtained from thermodynamic profiles generated by the 
                         GOES-10 satellite retrieval algorithm for South America. The 
                         validation is performed using the original covariance matrix, made 
                         by CIMSS, and with a new covariance matrix adapted to the weather 
                         conditions of South America tropical region. The dataset used was 
                         a total of 1095 radiosonde observations located in the South 
                         America tropical region at 00 and 12 UTC, as well as thermodynamic 
                         profiles from 12h forecasts of the Global Weather Forecast Model 
                         T213L42, used as firstguess, and upwelling radiances of 18 
                         infrared channels from the GOES-10 satellite for the period from 
                         July to November 2007. The results obtained with the new 
                         covariance matrix were better than with the old one. RMSE (Root 
                         Mean Square Error) and Bias reduced reasonably from 5.7 and 1.2 to 
                         4.1 and -0.3 mm respectively. On the other hand correlation 
                         coefficient between the precipitable water values from the GOES-10 
                         and radiosonde increased considerable from 0.75 to 0.88. This 
                         study shows that the GOES-10 soundings are able to provide support 
                         for many meteorological fields, mainly supplying the lack of data 
                         from upper air observations in good time and space scales.",
