Abstract:

On the basis of statistical model of the atmospheric aerosol the regression equations between values of aerosol extinction and backscatter coefficients at wavelengths of 355, 532, and 1064 nm are obtained. These equations were tested on calculated and measured data of AERONET. By means of numerical experiments the effectiveness of application of the obtained equations in algorithms of retrieval of profiles of b_pa(l) from three-wavelength lidar sounding of atmosphere is evaluated. A method for determination of volume concentrations H_2,5 and H₁₀ of atmospheric aerosol particles, corresponding to mass concentration standards PM_2,5 and PM₁₀, is proposed, which is based on multiple correlation between concentrations and b_pa(l).
