摘要
简单介绍了地基GPS遥感大气水汽含量的原理以及GPS反演水汽信息的种类,比较了两种GPS数据解算水汽策略,分析了在解算过程中影响GPS水汽精度的因子。最后简述了GPS水汽在气象上应用的进展,并提出了以后需努力的方向。
The paper provided an overview of the theory of remote sensing the atmospheric water vapor by ground-based GPS and the kinds of GPS water vapor information, then made a comparison between two of the strategies to obtain the GPS data solution for the GPS water vapor. The paper also analyzed those factors involved i＇n the GPS data processing which effect the precision of GPS water. Finally, the paper introduced the latest advance of GPS water vapor data＇s application on weather prediction , and put forward the future study obiective.
