Abstract

The variability of the volume concentration and mean radius of particles of the fine and coarse fractions of surface aerosol in summer has been studied from the results of solution of the inverse problem for spectral measurements of the aerosol extinction coefficient. It has been shown that the main contribution (80%) to the total volume of near-surface aerosol is made by particles of the coarse fraction. The mean radius of fine particles varies from 0.08 to 0.25 μm. The variation range of the mean radius of coarse aerosol is 1.06–3 μm. The influence of atmosphere smokiness on variations in microstructure parameters is considered. The variability of retrieved microstructure parameters of near-surface aerosol is compared with similar results obtained from solar photometry data.

Keywords:
