Elevation model

Including the orography

The distribution of air pollutants often shows a strong correlation to the terrain elevation. For example, ozone concentrations at night are occasionally higher at higher elevations than in the valleys.

In FLADIS, the terrain elevation may be taken into account explicitly by using a Digital Elevation Model for the area of interest.
