✦ Synopsis

This paper deals with the analysis and simulation of air pollutant dispersion in the region of Berlin. Results from simulations of a winter smog episode are presented. A concept of a simulation package for summer smog consisting of a complex meteorological model, an air chemistry model, and a dynamic model of emissions for data input is described. It is pointed out that a system of such numerical models is very complex. Simulation runs and scenario analyses take hours of computing time, even on today's supercomputers.

Therefore a strategy for model decomposition and implementation on massively parallel computers is described. As an example this is carried out on one particular atmospheric model.
