The atmospheric dispersion models are used to calculate concentrations of air pollutants on different scales, from local to continental scale. To analyse the interacting effect of all scales a coupled model concept is applied.
The models are important and useful tools in many applications such as producing Air Quality forecasts, social planning and investigating the effects of emission scenarios regarding Air Quality, health effects and external costs.
MATCH is a transport and chemistry model operating on urban to global scale. The model surveys emissions of chemical components into the atmosphere along with meteorological data for calculating the transformation, transport and deposition of air pollution.
SIMAIR is a family of internet tools for the investigation of Air Quality in areas with road traffic and/or residential wood combustion. The model system calculates the interaction of air pollution on different spatial scales by a coupled model concept, using different models on regional, urban and local scale.
Development of the model system SIMAIR is currently being carried out with the aim of highlighting and visualising the differences and consequences of different emission scenarios.
