JUNGLE CANOPY PENETRATION. VOLUME 1. DIFFUSION MEASUREMENTS

Abstract

An investigation was made of the ventilation processes of a tropical rainforest. A convenient and proven technique for such an investigation involves the release of an aerosol tracer above the forest. The ventilation of the forest is then measured in terms of the extent to which the tracer penetrates the canopy, and moves horizontally within the forest. Penetration of the canopy and lateral movement within the forest by an aerosol are influenced both by the forest and by meteorology. Since the forest is in a sense a parameter, a complete description of the vegetation is essential to extrapolating the results to other sites. The importance of meteorology in diffusion clearly requires the collection of meteorological data. Zinc cadmium sulfide, which fluoresces under ultraviolet light was selected as the tracer.
