Abstract:

The paper presents the generalized empirical model of the aerosol optical characteristics in the lower 5-km layer of the atmosphere of West Siberia. The model is based on the data of long-term airborne sensing of the vertical profiles of the angular scattering coefficient, aerosol disperse composition, as well as the content of absorbing particles. The model provides for retrieval of the aerosol optical characteristics in visible and near IR wavelength ranges (complex refractive index, scattering and absorption coefficients, optical depth). The input data are the values of the angular scattering coefficient μ(45º, 0.51 m), particle size distribution function, concentration of absorbing substance ("soot"), parameter of condensation activity, and relative humidity of air at different heights.
