Retrieval of aerosol optical and microphysical characteristics according to data of ground-based spectral measurements of direct and scattered solar radiation. Part 1. Testing of algorithm

Abstract

The ground-based measurements of direct and scattered solar radiation to date serve as the most reliable source of information on the columnar optical and microphysical characteristics of atmospheric aerosols. We suggest an algorithm which combines the iteration retrieval of the optical single-scattering characteristics directly from the data of photometric measurements and the solution of the linear inverse problem which ensures the retrieval of the microstructure of homogeneous aerosol particles and complex refractive index of the aerosol material. Software, developed to make the routine experimental data processing more efficient, is described. Results of algorithm testing on different mono- and multi-component aerosol models are presented.
