Lagrangian-particle air pollution model is required by Slovenian legislation for industrial air pollution control because it is the most efficient for small domains over complex topography. To determine its performance and efficiency for regulatory purpose a research is made. In this research a general purpose modelling system designed for local scale areas is used. The main goal of the research is to define an enhanced statistical analysis used to evaluate an air pollution model of this kind where an operational configuration of both input data and model parameters are used and a testing period with very complex dispersion conditions is used. This enhanced evaluation can help to better understand the general quality that a model can achieve in these conditions. It gives some idea on how to better evaluate and use some results that seem to be very negative simply looking to some statistical parameter. Keywords: air pollution, model evaluation, Lagrangian particle model, field data set. 1 Introduction In accordance with the European Council Directive of 28 June 1984 on combating air pollution from industrial plants (84/360/EEC) a Slovenian Government decree on the emission of substances into the atmosphere from stationary sources of pollution came into force in April 2007. The decree defines that the performance of the air pollution model used to reconstruct air pollution
