Surface Effects on Evaporation, Recirculation, and Dispersion in Light Winds.
Abstract
A joint U.S., UK, and Canadian Evaporation, Recirculation, and Dispersion in Light winds trials program was conducted at U.S. Army Dugway Proving Ground in July-August 1995. Program objectives were to: (1) obtain evaporation data from chemical agent simulants on sand, concrete, and aluminum surfaces; (2) document the effects of obstacle geometry and atmospheric stability on the accumulation and retention of material entrained into obstacle wakes; and (3) examine near-surface dispersion in low winds. The program produced data sets that can be used to validate evaporation and urban dispersion models, and provided detailed descriptions of dispersion in low winds. Based on an analysis of the data. new turbulence and stability indices are proposed to characterize surface layer dispersion.
