用曙暮光时的天光光强反演平流层气溶胶散射系数廓线

Retrieval of the Profile of Stratospheric Aerosols from the Intensity of Skylight During Twilight Periods

本文基于对曙暮光问题的系列研究,提出一个用曙暮光时的光强观测资料反演平流层气溶胶垂直分布的方案.然后在用Monte-Carlo计算程序模拟分析Koomen等人1951年曙暮光观测资料的基础上,对此资料实施了反演试验,并给出了反演基本结果和误差分析.结果表明此法是有效的,能为平流层气溶胶过去几十年的长期变化提供反演方法.

Based on a serial study on twilight problems, this paper proposes a scheme for retrieving the vertical distribution of stratospheric aerosols using the intensity observations during twilight periods. After simulations and analyses of Koomen's twilight data by a Monte -Carlo code, a retrieval test was carried out using this data set and the retrieval results and errors were discussed. Results show that this method may provide an effective retrieval method for studying the long-term variation of stratospheric aerosols.
