在无雨量资料地区，估计降雨量是很困难的。远程控制是近年来解决这一问题的重要途径。研究了TRMM降水资料在天山山区的适用性。将TRMM数据与2000 - 2010年21个气象台站的观测数据进行对比，发现两者在不同时间尺度和空间尺度上具有较好的一致性。结果表明，不同时间尺度下的相关系数（R2）均大于0.7。在不同空间尺度下，相对误差在-40%~40%之间。这也表明TRMM数据可以在研究区使用。这一分析对无资料地区的水资源研究具有一定的意义。
Estimation of the rainfall in the ungauged areas is very difficult. Remote is an important approach for resolving this problem in re-cent years. The applicability of TRMM precipitation data in Tianshan Mountains was studied in this paper. By comparing the TRMM data with observed data of the 21 meteorology stations from 2000 to 2010, we found there was a good consistency between them in different time scales and spatial scales. The results show that the correlation coefficient(R2) is greater than 0.7 in different temporal scales. The relative errors are between-40% and 40% in different spatial scales. It also indicates that the TRMM data could be used in the study area. This analysis is mean-ingful for the water resource study in ungauged areas.
