Abstract:

The atmospheric dispersion of the military obscurant smokes produced by the M3A4 fog oil smoke generator and 30-lb M5 HC smoke pots has been studied in a program of field trials carried out in a grassy meadow in south-central Indiana. The investigation focused on four areas. Measurements of the mass rate of release and exit temperature were performed to define the smoke sources. The smoke aerosol was 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 relative humidity at four levels on a 10-m instrument tower located on the test site. Measurements of the average smoke concentration over the period of release were carried out at 50 locations on 5 transects located 50, 100, 250, 450 and 675 m from the release point. At each location concentration measurements were performed at 1, 2, 3, 4, and 8 m above ground level except on the fifth transect where they were performed at 2 and 8 m.
