Abstract: First results of a dispersion modelling study in the city of Zurich are presented. Surface pollutant concentrations (yearly averages) at several monitoring stations were modelled using the Danish OML-Multi operational model and compared with observations. For this purpose a detailed SO₂ and NO_x emission inventory for the year 1990 was constructed. The results show an average overestimation of the observed NO_x concentrations of about 35% and an average overestimation of the observed SO₂ concentrations of almost 50% at 24 sites distributed all over the area of investigation.
