获取精确的面降水量是祁连山生态屏障建设以及河西及青海湖水系等水资源估算及合理利用的重要依据，但由于山地地形复杂、高山区监测稀缺等问题，目前相关结果之间差异较大且精度有待证实。为此，在祁连山中、高山区架设了23套T-200BM3、6套TRwS204称重式雨雪量计，两个降水观测误差对比观测场（海拔2 980 m和4 651 m）、1个不同类型雨量筒对比观测场（海拔2 980 m）及其配套观测设施，并结合祁连山及其周边27个国家气象站的中国标准雨量筒和GPM降水数据，估算了祁连山2019年、2020年面降水量。结果表明：各类雨量筒观测误差校正值比实测值平均增加约10%，在高山区降雪观测偏少约30%、总降水量偏...
