| 摘 要： | 提出了从宽谱太阳漫射辐射信息反演大气气溶胶折射率虚部的新方法。通过敏感性分析发现：宽谱太阳漫射辐射对大气气溶胶折射率虚部的变化非常敏感，而对粒子谱分布、气溶胶折射率实部、地表反射率、大气中水汽和臭氧含量的变化不很敏感或弱敏感，因此可以从中较好地提取大气气溶胶折射率虚部。数值试验表明该方法具有较高的精度。

| Abstract: | This paper puts forward a new method to retrieve the imaginary part of complex refractive index of atmospheric aerosols from wide-band solar radiation By the analysis of sensitivity,we found that:wide-band solar radiation is very sensitive to the imaginary part,at the same time,it is not sensitive or weakly sensitive to size distribution,real part,surface albedo and the amount of water vapor and ozone So it is very possible to retrieve the imaginary part from wide-band radiation The numerical experiments showed that this method has good precision |
