Abstract

The European air quality in 2010 was simulated by the regional air quality model CAMx in two different projects: Eurodelta-Trends (EDT) and PSI-Project. We used the same model version CAMx v6.50 and the same parameterization in both projects but with different domain resolution and input data. In this study, we investigated (i) how different are the results for ozone, PM2.5 and its components and (ii) which parameter/input is more critical for each pollutant. Our analyses suggested that the differences mainly originated from the boundary conditions, biogenic emissions and the vertical distribution of anthropogenic emissions. The most sensitive species to inputs were ozone and secondary organic aerosols (SOA). The difference in ozone concentrations was mainly due to the difference in boundary conditions. On the other hand, the difference in the annual PM2.5 concentrations originated mainly from SOA, due to different biogenic emissions used in the two projects. Concentrations of secondary inorganic aerosols (SIA) were comparable with small differences due to the different resolutions and vertical distribution of emissions. Although their generation was not the same, the meteorological data were similar in both projects and effects of small differences were not significant for the annual concentrations of pollutants.
