Ground-based measurements of direct and diffuse solar radiation are the most reliable source of information on aerosol optical and microphysical characteristics in the total atmospheric column. The algorithm integrating iterative retrieval of single scattering optical characteristics from photometric data and linear inverse problem solution on homogeneous aerosol particle microstructure and complex refractive index is presented. The software, developed with the aim to decrease labor expenditures during routine experiment processing, is described. Results of algorithm testing on the models of aerosol with one and more fractions are presented.
