The dynamics of forest-boundary-layer interactions over a forest edge have been an interesting research topic in recent years. A better understanding of edge flow has implications for the siting and interpretation of flux measurements near a forest edge. In the present study, we use large-eddy simulations with the newly developed multi-layer canopy model MCANOPY to investigate canopy flows, or more specifically scalar transfer, over a forest edge. Two important impact factors for edge flows are considered: the vertical distribution of foliage and the scalar source/sink distribution. The simulations show that both factors have non-ignored impacts on the scalar transfer over …
