Abstract:

We consider in this paper a single–parameter model for atmospheric variability of a scattering phase function of a near-ground haze. The domain of applicability of this model is considered as well. A role of random and regular geophysical factors in formation of the single–parameter model is analyzed based on model estimates. The analyzed model of correlation between aerosol light scattering characteristics is shown to correspond to the really observed wide variety of dispersion composition of the near-ground atmospheric haze, provided that optical constants of aerosol particles vary widely and the aerosol particle size spectrum changes characteristically with changing relative humidity of the atmosphere. Application of the single–parameter model is more justified for atmospheric situations, in which significant dynamics of the relative humidity is observed.
