三峡区间TMPA和IMERG卫星降水产品精度评估
Assessing Accuracy of TMPA and IMERG Satellite Precipitation Products in the Three Gorges Region
摘要
Abstract
In an attempt to verify the feasibility of substituting ground observation data with satellite precipitation da-ta, the accuracies of TMPA 3B43V7 and GPM IMERG satellite precipitation products in the Three Gorges Basin were evaluated by statistical analysis based on the observation data from ground sites. The results reflected that TM-PA and IMERG showed good consistency. In the upper flat area of the Three Gorges Region with low latitude, the accuracies of satellite precipitation products were poor, whereas in the alpine-gorge area in the lower reach of the Region, the latitude was higher, and the accuracies were better. Satellite precipitation products have the potential of replacing ground site precipitation data, and are applicable in the study basin.关键词
