Abstract

The paper presents the results of long-range atmospheric model developed specifically for the Southern hemisphere conditions. The model utilizes a combined Eulerian-Lagrangian description of the transport and diffusion of pollutants, calculation of their chemical transformations, dry and wet deposition as well as the pH value of precipitation.
