Zasavje canyon regional online air pollution modelling system in highly complex terrain - description and validation
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.
