Spatial Variability of Turbulent Fluxes in the canopy Sub layer of a Uniform Pine Stand


The Objective of this study is to examine whether single tower turbulence statistics measurements represent the flow properties of RSL (roughness sub layer) turbulence above a uniform, even-aged forest as a best-case scenario for natural forested ecosystems, many of which are not even-aged and are often populated by multiple dominant species. Specifically, the Spatial Variability of turbulence statistics, the spatial homogeneity of scales similarity relations, and the influence of local canopy morphology on characteristic length/time scales are analyzed. These objectives address whether single-tower measurements represent horizontally averaged flow statistics, canonical similarity structure of turbulent transport, and the influence of canopy morphology on basic characteristic length and time scales governing vertical transport of mass heat and the momentum.
