摘要

本文将已发表的不同地理区域大气尘埃气溶胶复折射率数据与美苏联合观测期间收集的尘埃气溶胶样本数据进行了比较。1989年在塔吉克斯坦的实验。讨论了用于估计折射率虚部的各种方法的缺点。粉尘气溶胶的e值有相当大的范围，这对光学特性模拟是至关重要的。现有的差异可能是由于所使用方法的不确定性以及来自不同地理位置的粉尘气溶胶的特定化学成分。

Complex refractive index of atmospheric dust aerosols

This paper compares published data on the complex refractive index of atmospheric dust aerosols, for different geographical regions, with data obtained for dust aerosol samples collected during the joint U.S.S.R.—U.S. experiment in Tadzhikistan, 1989. The disadvantages of methods used for estimation of the imaginary part, æ, of the refractive index are discussed. There is a considerable range of values of æ for dust aerosols, which is crucial for optical characteristic simulation. The existing discrepancy in æ can be due to uncertainties in methods used as well as due to the specific chemical composition of dust aerosols from various geographic locations.
