利用地基GPS的手段对北极黄河站可降水量进行了研究，分析了影响可降水量计算的三个因素：天顶总延迟、天顶干延迟和大气加权平均温度，验证了天顶总延迟和天顶干延迟的可靠性，得到了适合北极黄河站区的大气加权平均温度模型，并且将GPS可降水量与无线电探空的结果进行了比较，得到两者差值的标准差优于2 mm。

A ground-based GPS method was used to measure precipitable water vapor ( PWV) at Arctic Yellow River Station.Three factors that affect PWV were analyzed:Zenith Total Delay, Zenith Hydrostatic Delay, and weighed mean temperature.The reliability of Zenith Total Delay and Zenith Hydrostatic Delay was proven, and the model of weighed mean temperature was applicable for Yellow River Station in the Arctic.In a comparison of GPS-measured PWV and radiosonde data, the root mean square was less than 2 mm.
