PROPAGATION OF IMPURITIES IN THE ATMOSPHE RE WITH CONSIDERATION FOR THEIR CONDENSATION

Propagation of impurities in the atmosphere is mathematically modeled, the kinetics of condensation of vaporous components of impurities on natural atmospheric aerosol being taken into account. The model is int ended to calculate the long-range transport of impurities, their conde nsation being taken into account. The information from the available d ata files on the fields of meteorological elements can be used for the input parameters in this model. The model is applied to calculate the fields of concentrations of sulfuric acid vapor and sulfur dioxide, a nd to calculate the size distribution of acid-containing aerosol parti cles produced in the atmosphere. The calculations are performed for th e three-dimensional mesh space stretching over the most part of Europe . The local atmospheric volumes characterized by the enhanced concentr ation of acid-containing aerosol are identified.
