After rain comes sunshine: canopy and forest floor interception

We found that canopy interception has a clear seasonal trend ranging from 15% of rainfall in summer to 7% in winter for the beech forest. On the other hand, forest floor interception appears to be constant over the year and evaporates on average 22% of throughfall.
Spatial throughfall patterns were also investigated, and showed the persistence of hotspots (locations with concentrated throughfall) and the importance of tree structure for throughfall patterns. By use of a 'virtual experiment' the effect of these throughfall patterns on soil moisture was analysed with a developed statistical tool.
In this presentation I will elaborate on the measuring techniques, the results, and the analysis of the data with different model approaches.
