大气中水汽造成的路径延迟的测量误差是目前卫星高度计存在误差的重要原因 ,这种误差对高度计数据的分析应用产生很大的影响。介绍了高度计大气湿度校正的 2种方法 ,并对它们的结果做了比较。最后分析了大气湿度校正对高度计数据应用的影响。
The measurement error of path delay caused by water vapor in the atmosphere is an important reason for the current satellite altimeter error, which has a great impact on the analysis and application of the altimeter data. Two methods of altimeter atmospheric humidity correction are introduced, and their results are compared. Finally, the effect of atmospheric humidity correction on the application of altimeter data is analyzed.
