CMORPH daily rainfall estimations were integrated with rain gauge measurements in Brazil between 2000 and 2015, in order to reduce daily rainfall estimation errors by means of the statistical objective analysis scheme (SOAS). Early comparisons indicated high discrepancies between daily rain gauge rainfall measurements and respective CMORPH areal rainfall accumulation estimates that tended to be reduced with accumulation time span (e.g., yearly accumulation). Current results show CMORPH systematically underestimates daily rainfall accumulation along the coastal areas. The normalized error variance (NEXERVA) is higher in sparsely gauged areas at Brazilian North and Central-West regions. Monthly areal rainfall averages and standard deviation were obtained for eleven Brazilian watersheds. While an overall negative tendency (3 mm·h^-1）估计，亚马逊流域表现出长期的积极趋势。每月的平均降水量和各自的空间标准偏差紧随数据丰富的流域的幂律关系，即与密度较差的雨量计网络。每天的SOAS降雨积累也用于计算3天降雨发作的频率的空间分布大于100 mm。秘鲁安第斯山脉，玻利维亚亚马逊盆地和拉普拉塔盆地以及沿巴西海岸的频率大于3％的频率被确定为下风，在那里，降水反复触发了滑坡。SN -1687-9309 UR -https：//doi.org/10.1155/2018/2095304 DO -10.1155/2018/2095304 JF-气象学PB -Hindawi KW -er -er- ER-
