A field investigation was initiated in the summer 1978 to quantify the influence of meteorological factors, ignition method, and fuel conditions on the behaviour of smoke plumes from open field burning. Measurements of air quality and meteorological conditions were performed…

The motion of a strong line thermal in an unstratified atmosphere is modeled to estimate a bound for its capability to life firebrand particles. It is found that the maximum height of a viable firebrand is roughly proportional to the square root of thermal strength. The…

The high variablility of burning conditions and fuels, found in Alaskan forest fires, produces an associated complex emission of particulate matter. Histological evidence of some large particles has been found in the forest fire plumes as well as aerosols resulting apparently…

We have used the high optical absorptivity of urban and source particulates to trace their ‘graphitic” component. The optical absorptivity and the particu late carbon loading show a strong correlation. Analyses of the data indicate that primary soot emissions compose a major…

'Two studies were undertaken. An initial study in 1974 produced results that indicated significant losses of nitrogen and some other elements. The study was repeated 1981 as a check on the results of the 1974 burn, and to provide an assessment of the methods used in the first…
