CHARACTERIZATION OF FOREST VEGETATION ANALOGS

Abstract

Significant features of diffusion have been delineated which are influenced by forest characterization and associated met conditions. This study outlines the vertical transport of material or momentum through the canopy and in the boundary layer above the forest and its significance. This study involved an investigation of gross forest influences that may be involved in diffusion and met measurements in a variety of forests. Data from diffusion and munition tests in forest environments were analyzed to delineate differences between forests of different physical characteristics. Above-canopy wind speeds for various forests were plotted as a function of the below-canopy wind speeds and an Environmental Index developed. The study developed techniques for characterizing the significant properties of a forest (aerosol diffusion) on the basis of relatively simple physical forest measurements, followed by a trial application of statistical approaches, using a section of forest in Thailand.
