This is a traditional topic in micrometeorology. It is valuable to continue to have one or more sessions at AMS 35th Conference on Agricultural and Forest Meteorology. Work using field observations and laboratory experiments, and modeling techniques (large-eddy simulation, direct numerical simulation, Reynolds averaging closure models, Largrangian stochastic diffusion and footprint models), to advance our studies of turbulent transport, dispersion and diffusion processes in and above both horizontally homogeneous and heterogeneous vegetation canopies, over flat or uneven topographies, in various stability conditions, are all worthy presentations. Modeling work that couple canopy-scale turbulence model into large-scale models such as WRF also fits in this session.
