Summary, in English

The contribution of the understorey vegetation to the spectral reflectance from the top of a forest canopy was investigated by the use of a forest canopy reflectance model. Detailed field data, i.e. forest leaf area index (LAI), tree structural parameters like the height, diameter and crown length of the trees, and the composition, distribution and reflectance of the forest floor, was collected for some common forest types in southern Sweden and used as input data to the model. Results verify that the impact of the understorey to LAI estimates is of major importance and varies with both the understorey distribution and the forest properties.
