Comparison of measured and modelled N02 values at Zurich airport, sensitivity of aircraft NOx emissions inventory and N02 dispersion parameters

摘要

This paper presents a comparison of modelled and measured annual mean N02 concentrations around Zurich airport. Modelled concentrations were derived from the LASA T Lagrangian model for the airport and from a Gaussian plume model for the Zurich canton. The measured annual mean N02 concentrations were monitored at stations within the airport. The modelled airport N02 concentrations fell below 1 ug/rrr' 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.
