Abstract
In the paper, a national project with the title \“Prognostic and diagnostic
integrated regional air pollution modelling system” is described. It shows that
such a project can significantly contribute to the proper understanding of the air
pollution in smaller regions with a very complex topography. It also describes
how foreseen scientific problems were solved and the necessary testing,
improvements and validation were made. The development of a Lagrangian
particle model-based air pollution modelling system that works in an on-line
diagnostic mode and covers air pollution from several industrial and other
sources in the region over a highly complex terrain, is described. To achieve online
efficiency some new methods of obtaining high resolution short-range
meteorological fields derived from mesoscale models were developed and the
implementation of advanced Lagrangian models, acceleration techniques and
novel approaches for whole system integration are presented. The project’s test
bed was established as a novel approach to the overall treatment of the scientific
– applicative project goal.

1 Introduction
In some areas of Slovenia, local inhabitants or environmental associations are
strongly against the operation of some industrial plants due to the air pollution
they cause. These problems are regulated by the European directive of Integrated
Pollution Prevention and Control (IPPC) which requires among others that the
industrial source’s influence on the ambient air is modelled once to obtain the
