Abstract: The air quality modelling system WRF-CMAQ was applied by the Bulgarian NIMH (National Institute for Meteorology and Hydrology) team to the European domain in the frame of the Air Quality Model Evaluation International Initiative, Phase 2 (AQMEII-2). The model system was set up for the European domain of 5000×5000 km size with horizontal resolution of 25 km. The emissions were available through AQMEII and further processed in a way to feed the chemistry transport model CMAQ. The meso-meteorological model WRF was driven by NCEP GFS data with 1°×1° resolution. The chemical boundary conditions were extracted from MACC global simulation data. Model performance was investigated by means of AQMEII-2 web-based evaluation platform ENSEMBLE. A preliminary model evaluation for ozone and particulate matter was conducted based on comparison between simulated and observed concentrations at different type of surface stations in the EU wide domain. Model performance was characterized by overestimation for ozone and underestimation for the other pollutants. The relative statistical indicators were also discussed in view of recently published performance criteria.
