摘要：Hydrological scale is the leading issue in hydrology research. Precipitation is one of the biggest uncertain factors in runoff simulation and the most important information in flood forecasting. It is necessary to study the influence of time scale on the precision of satellite rain measurement. On the basis of the study of the daily scale accuracy test of the meteorological satellite rain measurement, the precision of the annual and monthly scale was checked, and the variation law of the rainfall precision of the TRMM rainfall measurement data on the time scale was finally obtained.
