Abstract
This paper presents a statistical microphysical model of atmospheric aerosols for the spring-summer-autumn period for the territory of Belarus and Poland developed at the base of long-term measurements at AERONET stations, carried out in Minsk and in Belsk (Poland). This model can be used for atmospheric correction of the Earth satellite monitoring data. Under this model aerosol consists of two fractions (fine and coarse), each of them having a lognormal particle size distribution, a fixed average size and rms, and fixed values of the real and imaginary parts of the refractive index. An aerosol coarse fraction consists of two components, containing spherical and non-spherical (spheroidal) particles. The only variable parameter of this model is the ratio of volume concentrations of fine and coarse fractions. It is shown that the parameters of the developed Belarus and Poland aerosol model are very close to those for the moderately absorbing aerosol model used for West Europe.
