The paper presents selected results of an urban scale analysis of air quality. Calculations are carried outfor the Warsaw area, basing on the emission and meteorological dataset for the year 2012. The regionalscale CALMET/CALPUFF modeling system has been used to link the emission data with the resultingconcentration maps of the selected polluting substances that characterize the urban atmospheric environment:PM10, PM2.5, NOx, SO2, CO, C6H6. The emission field encompasses the basic activities in an urbanarea: the energy sector, industry, traffic and the municipal sector. The basic simulation results present theannual mean concentrations of pollutants at the receptor points and indicate the areas where air qualitylimits are exceeded. The presentation is focused on the assessment of the model performance. Thecalculated annual mean concentrations are verified against the measurement data at 5 monitoringstations. Moreover, for selected modeling periods (January 2012), performance estimates are also presentedfor 1-h concentration results. The good performance of the model is shown for the annual meanpredictions, while the temporal agreement of the short-term, 1-h average concentrations is much lessaccurate, especially for the low-wind meteorological episodes
