Field Measurement and Model Evaluation Program for Assessment of the Environmental Effects of Military Smokes: Field Study of Fog-Oil Smokes
Abstract
The atmospheric dispersion of the military obscurant smoke produced from SGF-2 fog oil with the M3A3E3 prototype fog oil smoke generator has been studied in a program of field trials carried out at Dugway Proving Ground. The investigation focused on four areas. Measurements of the mass rate of release, exit velocity and exit temperature were performed to define the smoke source. The smoke aerosol was physically characterized in terms of the particle size distribution. A description of the prevailing meteorology was obtained from measurements of the wind speed, wind direction, temperature and dew point at five levels on each of two 32-m instrument towers located on the test site. Measurements of the average smoke concentration over the period of release were carried out at distances of 25 - 800 m from the release point. At each location measurements of average concentration were performed using adsorbent-filled sampling tubes positioned 1.5 m above ground level. Deposition measurements were also carried out at these locations using glass fibers filters as surrogate- surface collectors.
