AB: The Amazon is the world's largest, discharging more water to the ocean than any other river. Study of the world's fresh water sources becomes more significant with increasing awareness of global climate change and its potential affect on those resources. In this paper, we present a data reanalysis of the daily discharge and the respective gauge height for 87 active gauge stations throughout the Amazon River Basin. The data set was originally obtained from the ANEEL (Brazilian Electricity Regulatory Agency). The reanalysis consists of normalizing the decimal notation, filtering inconsistencies, and filling in missing data by an averaging procedure. These three problems proved to be nontrivial ones and prevented full benefit from the data. Having the reanalyzed data available will help improve understanding of the spatio-temporal variations of the water budget component of the Amazon basin, corresponding to the fundamental and difficult problem of modeling basin and continental scale hydrologic routing models.
