Since representative measurements focused on heterogeneous effects are scarce numerical modelling can be used to interpret the measurements. Recently, the atmospheric boundary layer (ABL) model SCADIS (Sogachev et al., 2002, Tellus 54B, 784-819) has been successfully applied to analyze the mechanisms of CO2 flux formation near a forest edge for neutrally stratified conditions (Sogachev et al., 2008, Ecological. Appl. 18, 1454-1459). In the present work, we apply the SCADIS with enhanced turbulence closure including buoyancy for investigation of the spatial distribution of latent and sensible heat vertical fluxes over patchy forested terrain in Denmark during selected days in the summer period. A closer look at the result shows that though the meteorological mast is located in the middle of a forest patch by size about 1x2 km2, it is not free from uncertainties regarding energy balance closure. Comparing observed and SCADIS (1D and 3D) simulated data for the mast confirms that caution is needed when interpreting measured flux data. The approach used in this work can be utilized in interpretation of already existed experimental data and in the planning of future experiments.
