摘　　要：为评估多源融合降水产品在陕西区域质量,文章利用陕西省99个国家级自动气象站质控后逐小时累计实测降水数据,对2018年国家气象信息中心研发的三源融合逐小时降水产品进行检验评估。结果表明:1)多源融合降水产品存在一定程度低估现象,但总体上与实测降水相关性较好,降水命中率较高,尤其在秋季质量较好;2)多源融合降水产品质量与海拔、坡度无显著相关性,在所选区域东南坡表现较好;3)受复杂地形影响,多源融合降水产品在延安北部和榆林东南部地区质量较好。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.
