As a result, there are now many national emission databases and model systems that, at least partially, suit the environmental management needs of national and international authorities. The level of aggregation of these data and systems tends, however, to be too high f

When looking at pollutant dispersion and air quality modelling it is necessary to have an accurate and high quality description of the emission sources in terms of quantity and dynamic behaviour. This requires an emission in

However, experimental data for model validation are particularly scarce for some specific conditions such as a stable atmosphere with calm or light

The complexity of the overall problem calls for the use of mathematical modelling tools, of so-called air pollution models. Analysing the potential for the practical use of air pollution models implie

But the definition of model quality is not a simple task and there is no universal approach. Within EUROTRAC-2 it has been recognized that m

Application can be read here as contribution to the solution of environmental problems. More specifically, the results of environmental science can be expected to play — directl
