| 摘 要： | 详述了使用太阳光度计反演大气水汽柱总量的反演方法—单通道法和双通道法，其中双通道法又可采用不同
的非水汽通道来实现。考虑到气溶胶光学厚度及瑞利散射的影响，分析了不同方法反演所得水汽总量相对探空数据的
误差。结果表明，这些方法的反演结果非常接近。在实际应用中，可使用任一种方法来反演水汽。

| Abstract: | In this paper, methods of retrieving total column water vapor by using sun photometer are described in detail, which
include single-channel method and double-channel method, and the latter can be achieved by using different non-water channel.
The infl uence of aerosol optic depth and Rayleigh are considered, and the data acquired by radiosonde are used as true value of
total column water vapor. Analysis on errors shows the retrieved results are very close by using varied methods. In practice, each
method can be equally used to retrieve columnar water vapor content. |
