Abstract: Zasavje is an industrial region in Slovenia located along the Sava River's steep canyon where PM10 air pollution is a major problem. In the paper a national project with the title 'Prognostic and diagnostic integrated regional air pollution modelling system' is described where it is shown that such a project can significantly contribute to the proper understanding of air pollution in smaller regions with a very complex topography. To achieve online efficiency some new methods to obtain high resolution short-range meteorological fields derived from meso-scale models have been developed and the implementation of the advanced Lagrangian model's acceleration techniques and novel approaches for the whole system integration is presented. The project's test-bed was established as a novel approach to the overall treatment of the scientific-applicative project goal.
