摘　　要：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 uncertainty in path delay measurements has become the major error source of altimeter data and has significant effects on its application to oceanographic studies Two methods for atmospheric water range correction are introduced and the comparison between their results are made The effects of water range corrections on application of altimeter data have been discussed as well
