摘要热带降雨测量使命（TRMM）多卫星降水分析实时产品3B 42 RT（TMPA-RT）数据用于径流预测的潜在效用，既通过直接比较TMPA-RT估计与网格化的测量产品，也通过评估南美拉普拉塔流域（LPB）四条支流的径流模拟，使用两种降水产品，进行了研究。评估表明，TMPA-RT为基础的径流模拟的相对精度和水文性能普遍提高后，2005年2月。2005年以来TMPA-RT的改进与2005年2月初TMPA-RT算法的升级密切相关，其中包括使用额外的微波传感器[地球观测系统高级微波扫描辐射计（AMSR-E）和高级微波探测单元-B（AMSU-B）]和实施不同的校准方案。这项研究表明，水文预测具有相当大的潜力...
AbstractThe potential utility of the real-time Tropical Rainfall Measuring Mission (TRMM) Multisatellite Precipitation Analysis real-time product 3B42RT (TMPA-RT) data for streamflow prediction, both through direct comparisons of TMPA-RT estimates with a gridded gauge product and through evaluation of streamflow simulations over four tributaries of La Plata basin (LPB) in South America using the two precipitation products, is investigated. Assessments indicate that the relative accuracy and the hydrologic performance of TMPA-RT-based streamflow simulations generally improved after February 2005. The improvements in TMPA-RT since 2005 are closely related to upgrades in the TMPA-RT algorithm in early February 2005, which include use of additional microwave sensors [Advanced Microwave Scanning Radiometer for Earth Observing System (AMSR-E) and Advanced Microwave Sounding Unit-B (AMSU-B)] and implementation of different calibration schemes. This study suggests considerable potential for hydrologic prediction ...
