Airborne lidar measurements of ca 4 squarekilometer (with the Weidenbrunnen FLUXNET site in the
northern quarter) for topography and a vegetation surface digital model, with resolution of 1 m,
accuracy of 0.15 m.
From the difference between topography and a vegetation surface digital model we derived tree heights
in the entire area (as input for large eddy model and ecosystem model simulations).
There are 30 forest inventory plots within the area, with ground based tree density, tree height, and PAI

measurements, so we derived e.g. regressions between height and PAI for PAI estimates for the entire
area.
