摘　　要：概述了利用地基ＧＰＳ接收机遥感大气水汽总量的一般方案，分析了各种因素导致的误差以及相应的消除或降低办法，总结了由湿项延迟计算水汽总量的方法．介绍了ＧＰＳ／ＳＴＯＲＭ试验和两种解算方案．最后提出试验研究方案和在我国进行业务应用要解决的问题．The general scheme of remote sensing of atmospheric precipitable water (PW) using ground based GPS receiver is reviewed. The errors caused by different factors and the corresponding ways to avoid or reduce the errors are elaborated,and then the ste pping of estimating water vapor from zenith wet delay is summarized. The GPS/STORM experiment and two methods to resolve PW are recommended. Finally,a set of solution to experiment and research is provided,and the problems on operational application in China are discussed.
