A simple, inexpensive, and relatively accurate photographic method for date collection is described. Objects of interest are triangulated from films taken simultaneously at two camera positions. Accumulated synchronization and measurement errors amounted to 0.2 - 0.5 meter. The…

The history of the Clean Air Act is reviewed from 1955 to 1980. The 1980 Visibility Regulation is cited as the first federal clean air policy which specifically addresses prescribed burning. Thirty-six states containing National Parks and Wilderness areas are now required to…

It is shown that similarity solutions in strong buoyant plumes (plant or axisymmetric) exist if a local characteristic turbulent diffusion coefficient varies inversely proportional to the square of the local gas density in the plume. The similarity formulation implies that the…

The Department of Interior is actively engaged in the smoke management business from two apparently opposite viewpoints. In one case we are trying to prevent or extinguish wildfires and minimize adverse effects on air quality as well as other resources. On the other hand we are…

Experimental, free-burning wood fires larger than 5 ha were similar in convection column volume after the initial buoyant, ring-vortex rose from the ground. The fire generated strong vorticity patterns which propagated upward into the convection column. The rotation suppressed…

Recent estimates of particulate production from forest fires in the United States have ranged from 500,000 to 54,000,000 tons annually. This has been due partly to disparities in estimates of fuel that is consumed during the combustion process, but more to the choice of emission…
