Fine-Grid Resolution in Danish Eulerian Model and an Implementation on SGI Origin 2000 Computer

The transboundary transport of air pollutants and the chemical transformations during the transport (including here the photochemical reactions) are still causing great problems in the modern society. It is expected that this problem will become even more important in the near future. Therefore, the possibility to know in advance some typical situations with at least the most dangerous air pollutants (e.g. ozone) is of great interest of the environmental specialists and decision makers. In order to estimate the situation and take efforts to reduce the air pollution to some acceptable levels the output results of the air pollution models have to be obtained in real time (operational), over an appropriate scale and be as reliable as possible.
