| 摘 要： | 基于GPS反演技术的理论与方法,利用IGS站开放的观测数据和精密星历数据,选取北京、武汉、上海3个IGS站观测数据,通过GAMIT软件解算处理,得出3个站天顶方向对流层延迟量。由对流层延迟量和区域的平均温度,根据经验模型反演得出其大气水汽含量,并与探空水汽含量进行了比较,得出两者具有较好的一致性。同时分析了上述3个区域水汽变化特征,反演出大气水汽含量能较好反映区域天气参数的差异。

| Abstract: | Data from three IGS observation stations（Beijing,Wuhan and Shanghai） is selected by the open observational data and precise ephemeris data of IGS stations.GAMIT software is used to calculate the zenith direction troposphere detention quantity based on GPS inverse technology.From the experience models,atmospheric water vapor content is obtained by tropospheric delay and regional mean temperature.Compared with radio sound data,the conclusion is that the two methods have good accordance.After analysis of the 3 variation characteristics of regional water,the inversion of atmospheric water vapor content can well reflect the regional difference of weather parameter. |

| Keywords: | IGS station atmospheric water vapor content（PWV） radiosonde data regional variation of water vapor |
