      abstract     = {The impact of biogenic trace gases on tropospheric
                      chemistry, air quality, and the formation of secondary
                      products affecting our climate on a regional and global
                      scale are far from being understood. A considerable lack of
                      knowledge exists concerning a typical forest stand as a net
                      source of reactive trace compounds into the troposphere. The
                      concept of this study was to combine field experiments,
                      laboratory experiments investigating emission and uptake of
                      trace compounds by the plants, and modelling experiments
                      simulating the chemistry of biogenic trace gases and the
                      dynamics of a forest stand under well-defined conditions.
                      The chosen site was the forest area surrounding the
                      Forschungszentrum Juelich (Juelich Research Centre,
                      Germany). In order to simulate the dynamical properties, the
                      forest area was modelled to a scale of 1:300 and studied in
                      the large boundary layer wind tunnel at the Meteorological
                      Institute of Hamburg University. An area 3150 m long and
                      1200 m wide was replicated, including the upwind edges of
                      the forest. The model of the forest must reproduce the
                      resistance to the wind generated by this porous environment.
                      Rings of metallic mesh were used to represent the trees
                      following preliminary tests to find an arrangement of these
                      rings that provided the appropriate aerodynamic
                      characteristics for a forest. The turbulence properties of
                      the flow were measured in the wind tunnel within and above
                      the canopy. Subsequently, they were compared with field data
                      obtained at the Juelich Research Centre, in order to test
                      the quality of the modelling concept. The comparison showed
                      a good agreement and results with previous studies.
                      Tracer-gas experiments were carried out in the field within
                      the canopy, which were then in the wind tunnel. The order of
                      magnitude of the dimensionless concentration downwind of the
                      point source was in agreement. (c) 2005 Elsevier B.V. All
