Abstract
The results of comparisons of synchronous aerosol optical depth measurements made using sun photometers SP–6 and CE–318 and microstructure parameters recovered by solution of the inverse problem are presented. Measurements were carried out in Tomsk during a year. The volume concentration integrated over the whole depth of the atmosphere, and mean particle radius are considered as microstructure parameters. These parameters are evaluated for the total ensemble of particles and for fine and coarse aerosol fractions separately. We have shown satisfactory agreement between the compared parameters. Possible reasons for discovered discrepancies are discussed.
