This report documents a prescribed fire emissions inventory developed using consistent methodology for each of the 50 states of the USA for calendar year 1989. Emissions of particulate matter, selected toxic compounds, and a few other carbon-containing compounds are estimated.…

We develop a simple analytical model to estimate the thickness of a smoke layer formed by a plume of a large area fire and to account for crosswinds. We take advantage of the dominant flow features in the upper part of the rising plume and in the smoke layer far from the plume…

Until the end of July 1977, the fires in the forested and brush-covered land of California had been fewer than expected. The summer fire season was well along, and with less than average acreage burned, protection agencies were encouraged. Then a series of events dramatically…
