Air quality dispersion modelling for regulatory purpose: A European overview

Research output: Contribution to journalArticle


Air quality simulation models play an important role as a complement of air quality monitoring networks, and are essential tools the elaboration and implementation of Air Quality Management Plans and in performing Environmental Impact Assessment studies. The new Council Directive on Ambient Air Quality Assessment and Management presently under discussion in the Europea Council makes explicit mention of modelling techniques. In particular, in the article 4, paragraph 3 of the draft Council Directive, is expressed the need of establishing criteria and techniques for the use of tools other than measurement for assessing ambient a quality, particularly modelling. Models are called for as a supplement to measurements where these are mandatory (i.e. cities having more than 250,000 inhabitants and other zones where levels exceed limit values), and are the sole tool to be used in those situation where concentrations are below a given threshold. The paper addresses some topics emerged in the debate which is taking place in Europe about the role of regulatory models in the management of air quality. It appears that an effective use of dispersion and transformation models cannot take place unless some 'external' (i.e. prejudices against models) as well as 'internal' (i.e. improvements in model evaluation and use) issues are no overcome.
