EUMAC: European Modelling of Atmospheric Constituents

Chapter
Part of the Transport and Chemical Transformation of Pollutants in the Troposphere book series (3373, volume 1)

Summary

The EUROTRAC subproject EUMAC (European Modelling of Atmospheric Constituents) continued its work on the development of an advanced model hierarchy for air pollution dispersion simulations. The applicability of the long-range transport model system EURAD (European Air Pollution Dispersion Model System) to episodic simulations has been demonstrated for a variety of cases. Evaluation studies focusing on the meteorological as well as chemical parts of the system were conducted. Methods for nesting smaller-scale three-dimensional transport models into larger-scale ones were further improved. Applications of the former model type, in particular the EUMAC Zooming Model (EZM), are published in volume 7 of this series (Ebel et al., 1997a).

The chemical transport simulations were accompanied by sensitivity and process studies also using box models. First results from large-eddy simulations reveal the importance of concentration perturbations for their chemical transformation in the atmosphere. The role of biogenic emissions, aerosols and fog for chemical transformations were topics of further process studies. A major issue of this branch of research in EUMAC was cloud effects on the budgets of atmospheric pollutants.

Co-operative work with other EUROTRAC subprojects and other projects and programmes was continued, for instance, by pursuing comprehensive comparisons of long-range transport models. An important field of collaboration continues to be the generation of reliable emission models and scenarios for three-dimensional chemical transport simulations.
