Analysis of sensitivity of the optical characteristics reconstructed by the model of tropospheric aerosol of western siberia to uncertainties in the initial data

Abstract

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.
