Field Measurement and Model Evaluation Program for Assessment of the Environmental Effects of Military Smokes: Evaluation of Atmospheric Dispersion Models for Fog-Oil Smoke Dispersion
Abstract
This report provides an evaluation of four of the most promising mathematical models for the prediction of the dispersion of fog-oil smoke discharged from M3A3E3 or M3A4 smoke generators. The data base used for model testing consists of seven data sets: three field trials conducted at Dugway Proving Ground, Utah during March/April 1985 and four field trials conducted at Camp Atterbury, Indiana in November 1987. The results show that the four Gaussian puff models can predict within a factor of 2-3 under the convective and neutral conditions tested to distances of about 250 m. Beyond that distance, the plume tends to rise leading the models to significantly overpredict average concentrations at ground level. The model verification work shows that the particulate phase of a fog-oil plume acts like a tracer in its dispersion in the atmosphere -- for the short distances and stability classes tested with the Dugway and Camp Atterbury data. Keywords: Smoke deposition; Mathematical modeling; Fog oil.
