“…Atmospheric aerosols significantly affect the Earth's radiation budget by scattering and absorbing solar and thermal radiation [1][2][3] , then impacting the environment and climate [2][3][4][5][6] . The aerosol optical properties depend not only on the size and shape 1,7,8 , chemical composition 9,10 , relative air humidity RH 11,12 , but also on the size distribution of the absorbing substance (Black Carbon, Braun Carbon) in different fractions [16][17][18] . Measurements of the aerosol optical and microphysical properties in situ are important for radiation and climate calculations [19][20][21][22][23][24][25][26] .…”

The aerosol optical characteristics in the wavelength range of 0.46-0.87 μm were calculated on the basis of an empirical model of the aerosol optical characteristics in the summer background haze of Western Siberia. The Monte Carlo method was used to estimate the sensitivity of the model to uncertainties in measuring the input parameters: angular light scattering coefficient at a wavelength of 0.53 μm at an angle of 45°, mass concentration of the absorbing substance, and parameters of its lognormal size distribution, relative humidity of air. The relative errors in the reconstructed scattering, extinction, and absorption coefficients, single-scattering albedo, asymmetry factor, and lidar ratio are analyzed.
