INTERMEDIATE-SCALE AEROSOL CLOUD TRAVEL AND DIFFUSION FROM LOW-LEVEL AERIAL LINE RELEASES

Abstract

A series of low-aerial line releases of fluorescent particles under a variety of atmospheric stability conditions is being conducted at Dugway Proving Ground, Utah. Aerosol samples are obtained at ground level to 15 miles and aloft to 700 feet from tower and balloon mounted samplers. The first nine of these trials have been analyzed in terms of a diffusion model based on estimates of the vertical eddy heat flux obtained from mean temperature profiles and their change with time. Satisfactory agreement was obtained between calculated and observed dosages when the winds at release altitude were reasonably uniform and nearly parallel to the downwind sampling line.
