The problems are discussed on the dynamical modelling of vertical variations in the aerosol optical and microphysical properties as well as the methodology of constructing the information and modelling systems dealing with the aerosol light scattering properties. The question of the influence of gravitational sedimentation on the structure of aerosol anomalies under turbulent diffusion at different heights is considered in detail. A reduced approach to modelling of the coagulation transformation of particle size spectra is justified within the context of forecasting possible variations in the optical properties of hazes.
