| 摘 要： | 干延迟的精确确定对GPS气象中解算可降水分含量有很重要的作用。根据武汉和探空站Kingspark的探空资料，计算了这两地的实际干延迟量。在这些资料的基础上，用回归分析的方法对这两地的干延迟算式进行了建模和分析，发现该算式的精度优于其他模型。

| Abstract: | In order to separate water vapor content from GPS meteorology,the dry delay must be calculated firstly.This paper collected radio sounding data of Wuhan and Kingspark and computed dry zenith delay of these two places.In this paper,regression analysis is made use of modeling based on these data,and our algorithm is better than other empiric formula in these two places. |

| Keywords: | Dry zenith delay radio sounding data the model of atmospheric dry air correction |
