Regional Air Quality Modelling: A Few Examples of Recent Progresses and Remaining Questions

摘要

The rising concern of health impacts of atmospheric pollution necessitates an increasing need of acute understanding, accurate description and prediction of air quality. Major progresses in knowledge and techniques over several fronts have been achieved in the last decade or so (Monks et al., 2009). More chemical species have been characterized, with increased accuracy, and over larger and finer spatial scales. These progresses have been obtained through observations made during intensive campaigns and routine monitoring. Many progresses have also been obtained through regional-scale modelling, taking into account intercontinental transport and global-scale atmospheric composition changes. The objective of this paper is to give an overview of the contribution of regional-scale modelling to these progresses. It focuses on a selected sample of results obtained at the Institute Pierre-Simon Laplace (IPSL) in collaborative projects with INERIS, Meteo-France and the TNO in the Netherlands, among others.
