Controle de qualidade dos dados diários de chuva na Amazônia Legal brasileira (1998-2009)

Abstract : The reports of rainfall data can be altered for technical or human reasons. This study presents an approach to detect erroneous raingauges data in Legal Brazilian Amazon over the period (1998-2009). We examine the precipitation data from a target station with those of nearby stations belonging to a buffer. This buffer of 260 km is determined from the decorrelation of rainfall data versus the distance between the raingauges. Differences normalized of nine statistical criteria of a given station with the average of these criteria of nearby raingauges are calculated to build a risk index. This risk index shows a gloal quality of rainfall data used.
