Abstract
A scheme of the new stage of the development of a generalized empirical model of optical characteristics of tropospheric aerosol in Western Siberia is described. An algorithm is suggested for accounting the particle size distribution function of absorbing matter and the condensation activity of aerosols. Optical characteristics have been calculated with the complex refractive index of particles of different sizes variable with the relative air humidity. Using the “haze” type of the “aerosol weather” as an example, the results of model calculation are compared with the average experimental data on the angular scattering coefficient in a small-angle range and the spectral behavior of the aerosol extinction coefficients.
