Firstly, the GPS data in Naqu, Gaize, Deqn, Tengchong, Mengzi and Simao are processed, the change of remote sensing water vapor using six ground GPS receivers in Tibet Plateau and Yunan province are analyzed, the results based on GPS with those based on the radiosonde data are compared, and the relationships between the amount of atmospheric water vapor and the ground vapor pressure, ground temperature and precipitation are studied. It shows that the annual amount of atmospheric water vapor is about 0.2~2.0cm over Tibet Plateau and 0.5~4.5cm in Yunan province.

首先通过解算青藏高原那曲、改则和德钦以及云南腾冲、蒙自和思茅共6个站的地基GPS大气水汽探测资料，获得了这些站的大气总水汽量；分析了这些站的大气总水汽量的变化特征；通过比较那曲、腾冲、蒙自和思茅地基GPS遥感与探空结果，分析了地基GPS遥感结果的精度；同时还分析了大气总水汽量与地面气象要素之间的关系。
