Aerosol Dynamics Modelling in the Regional Chemistry Transport Model System Eurad
The particulate matter suspended in the atmosphere is strongly linked to numerous air pollution problems. These include the -direct and indirect- influences on the radiative budget of the atmosphere, the potential for adverse health effects, the influence of particles on the long-range transport of air pollutants and the interaction of aerosol particles with clouds. Therefore air quality models have to take into account particle formation, transport and deposition with respect to aerosol chemistry as well as aerosol dynamics. Due to the strong interactions between the gas phase and the aerosol phase, the aerosol model has to be fully coupled to a gas phase model. The Modal Aerosol Dynamics modelling technique as a time and memory efficient method provides a suitable approach to realise that purpose even in complex three-dimensional Eulerian models.
