A 1.3 hectare field containing hawthorn and alder was burned in April 1973. Post-burn analysis of 20 hawthorns and 20 alders determined the fire susceptibility of these species. Of those sampled, 80 percent of the trees less than 3 centimeters in basal diameter were killed. The…

Smoke particles absorb much of the thermal radiation from a large fire. This process affects the vertical velocity of the convection column. And it affects fire spread because of the effects of absorption on radiative heating of fuels ahead of the fire. The magnitude of these…

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…
