Abstract: This paper quantifies the ability of the emission and dispersion modelling system to reproduce observed pollutant concentrations in the vicinity of a European airport. For the validation, one receptor point was selected at Liszt Ferenc International Airport, terminal building 2, where an air quality monitoring station operates. Modelling results superimposed upon background concentrations generated from a suburban monitoring station in the vicinity were compared with hourly measured concentrations using statistical indicators for three compounds (CO, NO_X and PM₁₀). Acceptable correlation coefficients (0.53-0.76) were obtained, although in the case of PM₁₀ modelled values show slight but significant underestimation for the entire studied period. Also, an obvious overestimate of NO_X concentration was found for certain days. Pollution roses were generated that highlighted the spatial distribution of the pollution sources that affect the air quality at the receptor point. Sensitivity of model to input data, especially to the emission inventory is discussed. The contribution of aircraft ground movement and apron area emission was found to be well characterised, but in the case of CO and NO_X a small (15 ± 5%) deficiency was found for ground vehicles emission of parking area, and a much higher (65 ± 5%) difference was obtained for PM₁₀.
