【 摘 要 】

With the advent of satellite rainfall products, it makes up the shortage of information in the area with no regional rainfall information. It plays an important role in understanding the spatial and temporal rainfall distribution. By verifying the accuracy of satellite rainfall data, it can provide reference for data providers. Based on the reason of errors of rainfall data, it can further improve the accuracy of the meteorological satellite rainfall data. The accuracy of meteorological satellite rainfall data in day scale is verified with the monitoring data of the stations in the Heihe River Basin by Contingency Table Approach (CTA), Fuzzy Comprehensive Evaluation method and Correlation Coefficient method. Based on the results by the methods above, the classified graded method is proposed, providing a new method for the assessment about the accuracy of the satellite rainfall products.
