Abstract

The technique and results of calculation of spectral dependence of the single scattering albedo (SSA) of submicron aerosol in the visible spectral region with allowance for the lognormal size distribution of absorbing matter (black carbon) are presented. The ranges of albedo variations are estimated, and peculiarities of spectral behavior and variability of SSA are studied as functions of the median radius and the halfwidth of BC size distribution for dry and wet particles in the summer period. The generalized parameter of the coarseness of BC size distribution is proposed, which takes into account simultaneously the influence of the median radius and the halfwidth. It allows good approximation of the SSA dynamics as a function of the BC size distribution parameters for dry particles by a linear dependence.
