摘要
介绍用GPS测量提取水汽的原理和过程,讨论如何提高其精度和实时性,并提出构造三维水汽分布的方法。通过用GPS观测量反演大气的影响,从而提取大气中水汽的含量,这对气象研究和天气预报有很好的作用。
This paper introduces the principle and process of withdrawing vapor by GPS observations, discusses how to improve its precision and real-time Characteristic. and offers the method of constitute 3-dimisions vapor distribution, we can withdraw the content of vapor in atmosphere by effect of inversing atmosphere with GPS observations, which has perfect effect to the weather study and weather Forecast.
