| Abstract: | Summary The modification of the flow structure arising from the removal of large patches of trees in a managed forest plantation near
Gainesville, Florida is described. Using wavelet analysis of turbulence measurements taken above a forest canopy hundreds
of meters downwind from the forest gap and well outside the footprint, the present paper examines changes in flow characteristics
and demonstrates that the presence of the nearby clearcut introduces extraneous coherent events passing by the eddy-covariance
flux measurement system. |
