Abstract: This paper presents a comparison of modelled and measured annual mean NO₂ concentrations around Zurich airport. Modelled concentrations were derived from the LASAT Lagrangian model for the airport and from a Gaussian plume model for the Zurich canton. The measured annual mean NO₂ concentrations were monitored at stations within the airport. The modelled airport NO₂ concentrations fell below 1 µg/m³ beyond 3 km from the airport's sources. The correlation between measured and modelled concentrations depended on the dominating source. Concentrations for road vehicle dominated sources were underestimated by the model, whereas concentrations from aircraft dominated sources tended to be overestimated.
