Recently there have been significant improvements with respect to aerosol modelling. Models with 1-atmosphere approach are able to simulate both gaseous and particulate pollutants and suitable for episodic and annual calculations (Ackermann et al., 1998; Schell et al., 2001). There are also more complete models including full-science algorithms for aerosol modelling (Griffin et al., 2003; Bessagnet et al., 2004; Zhang et al., 2004). However, such models are more complex and demanding. A model intercomparison study showed that a more complex model approach to the aerosol problem does not automatically lead to better results in a 3-dimensional application (Hass et al., 2003). As long as speciated aerosol measurements with high time resolution are limited, the necessity of using so called full-science aerosol models is questionable. In this study, two air quality models with different approaches were applied to two domains, northern Italy and Switzerland, to investigate the capabilities, strengths and weaknesses.
