Abstract

The time variation of microstructure of the near-surface aerosol in the summer period has been studied based on solving the inverse problem for spectral measurements of aerosol extinction coefficient. Experimental data were obtained in Tomsk on a horizontal path using the measurer of spectral transmittance of the atmosphere at 11 wavelengths in the range from 0.45 to 3.9 μm. The numerical algorithm, based on the method of integral distributions, was used to solve the inverse problem. The volume concentration and the mean radius of aerosol particles with separation into a submicron and coarse fraction are considered. Specific features of the aerosol microstructure during the smoke haze in the atmosphere are determined.
