| Abstract: | An improvement of long-range air pollution transport and diffusion model which includes planetary boundary layer (PBL) dynamics and chemistry of SO2 and NOx, the processes of dry and wet deposition has been developed and used in the Southeast Europe. The transport and diffusion process are described on the basis of a combination of the Eulerian and Lagrangian approaches. A similarity theory is used for calculation of the PBL characteristics. A known linear chemistry module which includes 5 nitrogen and 2 sulphate species is incorporated. The model results for the region of Southeast Europe are in good agreement with the Meteorological Synthesizing Center West, Oslo information. |
