摘要： 利用地基GPS的手段对北极黄河站的可降水量进行了研究。对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进行分析，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比较，得到两者差值的均方根误差优于2个mm。

关键词: 黄河站, 对流层天顶延迟, 可降水量, 加权平均温度, 无线电探空

Abstract: This paper mainly discusses the method of calculating Precipitable Water Vapor at Arctic Yellow River Station by using ground-based GPS technique. Three factors Zenith Total Delay, Zenith Hydrostatic Delay and weighed mean temperature which effect PWV are analyzed, the reliability of Zenith Total Delay and Zenith Hydrostatic Delay is proved, we also get the model of weighed mean temperature fits for Yellow River Station region located in Arctic. With the comparison of GPS Precipitable Water Vapor and the result of radiosonde, the root mean square is less than 2 mm.

Key words: Arctic Yellow River Station, Troposphere Zenith Delay, precipitable water vapor, weighed mean temperature, radiosonde
