There were four radiosonde stations: ABRACOS, Rancho Grande, Rolim deMoura and Rebio Jaru, where the first two ones launched VIZ radiosondes and the otherslaunched Väisälä radiosondes. The quality control method was based on visual inspection,plausibility and spatial and physical consistency. The visual inspection corrected date andhour in files and name files, while plausibility checked surface measurements and its units.A statistical plausibility method based on temporal site series and its consistence with eachradiosonde at a 95% interval of confidence.was also applied. Finally the mass divergenceintegrated in the atmospheric column in a triangle which vertices were the radiosondestations were computed to verify the horizontal consistency of wind vector data. It wasverified that the substitution or elimination of suspected data improves the reliability ofthermodynamical parameters, for instance, CAPE. Consequently, it is stronglyrecommendable to use the corrected data series.
