| 摘 要： | 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。

| 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. |
