摘要: 比较和分析了北京、拉萨和武汉等跟踪站2002年7月的天顶对流层延迟和大气综合水汽的变化趋势,提出了无需进行其他转换利用天顶对流层延迟直接推算水汽含量的新方法,并对实测数据的计算结果进行了验证,证明了该方法的可行性。

Abstract: This paper compares and analyzes the change trend of zenith tropospheric delay (ZTD) and integrated water vapor (IWV) at BJFS, LHAS and WUHN stations in July 2002, and puts forward a new method which can calculate directly IWV using GPS ZTD without other transformations. The IWV calculated by the method is validated with the IWV computed by traditional method. The results show that the method is feasible
