The paper presents an algorithm for the prediction of regional scale sulfur deposition. The method is based on a dynamic, single-layer model of air pollution dispersion. The set of two transport equations, for the primary (S02) and secondary (S04) sulfur species is solved. Finally, the model generates spatial characteristics of the cumulated sulfur deposition due to transport and deposition processes, taking into account aerodynamical parameters of the terrain and chemical transformations. The model is aimed at evaluation of sulfur deposition originating from the major emission sources, representing the sector of energy generation. The emission intensity of each source and the time sequence of meteorological parameters within the period of simulation constitute the main input data. The model computes the contribution of each source to sulfur deposition over the prescribed time interval. The resulting total deposition map is a sum of individual contributions. The land-cover characteristics is an important factor in this calculation. Test computations were performed for the set of major power plants in Poland. The presented results refer to seasonal winter and summer depositions as well as the total annual value.
