Abstract:

A two-parameter model is presented in this paper, which allows retrieving the aerosol extinction coefficients in the visible and IR wavelength ranges on a horizontal near-ground path using a small number of parameters obtained in a local volume of air. The input parameters of the model are the aerosol angular scattering coefficient at an angle of 45° at a wavelength of 0.52μm and the mass concentration of crystal carbon in aerosol particles. The spectral dependence of the single scattering albedo in the wavelength range 0.4-3.9μm is estimated.

Keywords:

spectral dependence, aerosol extinction coefficients, absorption and scattering of optical radiation
