Meteorological Observatory Lindenberg – Richard Aßmann Observatory CONCLUSIONS Measurement-driven stand-alone simulations are a useful tool to study the model behaviour of the soil module TERRA in detail. Our validation activities focussed to soil moisture processes as a key factor in near -surface boundary layer modelling. By introducing some minor modifications the Bowen ratio could be improved in our one-month test data set at the measurement sites Falkenberg (grass) and Kehrigk (coniferous forest). The studies should be extended to several months in the annual cycle. In order to further improve the turbulent heat fluxes above forested areas the parameterisation of interception should be revised. In particular its quantitative effect on the latent heat flux should be more precisely derived from the measurements. Gerd Vogel (DWD FELG)
