Abstract To evaluate the quality of multi-source fusion precipitation products in Shanxi,the hourly precipitation data of 99 national observation stations in Shanxi after quality control are used to test and evaluate the hourly precipitation products of three-source fusion developed by the National Meteorological Information Center in 2018.The results show that the multi-source fusion precipitation product has a certain degree of underestimation,but it is generally well correlated with the measured precipitation.The precipitation hit rate is high,especially in autumn.The quality of multi-source fusion precipitation products has no significant correlation with altitude and slope,and the southeast slope of the selected area is better.Due to the influence of complex terrain,the quality of multi-source fusion precipitation products is better in the north of Yan'an and the southeast of Yulin.

Key words： multi-source fusion precipitation products test and evaluation Shanxi quality
