Abstract

Atmospheric aerosol microstructural parameters retrieved from spectral measurements of aerosol optical depth in the summer period in Tomsk are considered. The results were obtained using two algorithms for solving the inverse problem, a basic one and its modification presented in the first part of the paper. In the basic algorithm, the method of integral distributions is implemented. Having advantages of the method of integral distributions, the modified algorithm makes it possible to increase the accuracy of the estimate for the contribution of microdispersed particles to the aerosol microstructure. Statistical data about the retrieved parameters obtained for a total ensemble of particles with separation into the submicron and coarse fractions are presented. It is found that applying the modified algorithm permits one to additionally take into account up to 47% of the volume of submicron particles on average. At the same time, correction of the solution in the microdisperse range of particle size leads to a decrease in their average radius from 0.16 to 0.1 μm.
