EURAD: Europaeisches Ausbreitungs- und Depositionsmodell. Fortschritte bei seiner Entwicklung und Anwendung Abschlussbericht

Abstract

The European Air Pollution Dispersion Model System (EURAD), its further development and application is described. EURAD has been designed for regional episodic simulations of the transformation and transport of reactive species of anthropogenic and natural origin. The system consists of a meteorological, chemistry/transport and emission model. It is completed by a hierarchy of simplified versions, e.g. a box- and vertical one-dimensional chemical model, and process models, e.g. for the study of aerosol and fog effects. Several processes and sensitivity studies were conducted. In particular, simulations with different emission scenarios were carried out to investigate the effect of possible air pollution abatement strategies. Emphasis was put on the treatment of photo-smog episodes to gain a better understanding of the processes controlling them. Results from model evaluation and comparison studies are presented. The work was a contribution to the European environmental project EUROTRAC and was carried out in the framework of its subproject EUMAC (European Modelling of Atmospheric Constituents).
