Aarhus University produces 3-day forecasts for air pollution over Denmark, using the so-called Thor system.
The forecasts are published on a set of web pages in Danish. The pages include maps and graphs, showing the development of several air pollution components.
There are predictions for selected streets and urban areas, as well as general predictions for rural areas.
There is also a comprehensive set of pages in English, demonstrating the capabilities of the system for prognoses throughout Europe.
