Abstract
A technique is proposed for statistical estimation of the complex refractive index of absorbing aerosol using the data of field measurements of the optical characteristics of near-ground aerosol. The initial sub-array (165 realizations) of the refractive n(0.52) and absorption κ(0.52) indices of particulate matter is obtained from solution of the inverse problem for the wavelength of 0.52 μm. correlations of the obtained values n(0.52) and κ(0.52) with the optical parameters measured at the long atmospheric path and in the local volume are revealed. Iterative algorithm for estimation of the foregoing values separately for submicrometer and coarse aerosol is proposed. The errors in retrieval of the values n(0.52) and κ(0.52) are determined, they are δn=0,035 and δκ=0,016, respectively.
