Report of the National Commission on wildfire disasters: presented recently to Secretaries Babbitt and Espy, its message is clear: without aggressive, proactive wildland management programs begun now, the worst is yet to come

Created through the Wildfire Disaster Recovery Act of 1989 (PL 101-286), in response to the destructive western fire season of 1987 and the Yellowstone fires of 1988, the Commission was asked to consider the environmental and economic effects of disastrous wildfires through…

Layer replacement in wildland fire

Large, free-burning fires do not burn steadily. As most experienced fire personnel know, fire behavior varies significantly with time. It frequently can be described as pulsating. This pulsing is caused by a process called layer-replacement. As the burning creates a zone of hot…

Prescriptions for biomass fire smoke reductions

Planning prescribed fires for optimal periods which results in emissions reduction is an extremely useful air quality management technique. New information suggests that one more useful tool in smoke management may involve using the capacity of the atmosphere to remove smoke…

Weather modeling for wildfire behavior and smoke management

A major problem with weather data in complex terrain is temporal and spatial interpolation. The British Columbia Forest Service, through the services of Atmospheric Dynamics Corporation, has adapted a meso-scale weather model to provide hourly predictions out to 4.5 days for a…

Quantification of major components emitted from smoldering combustion of wood

The major condensible products (-45ºC) from smoldering combustion of ponderosa pine sapwood have been identified and quantified. Methylene chloride extracts of the condensate, as well as nonextracted condensate, were analyzed by gas chromatography/mass spectrometry (GC/MC). Non-…

NOx pollution from biomass burning: a global study

We present estimates of nitrogen oxide (NOx) emission from worldwide biomass burning totaling ~13 Tg N yr-1 on a 1 degree longitude by 1 degree latitude grid. Roughly 80 percent of these emissions occur in the zone from 25N to 25 degrees S. The inventory presented here is…
