Modeling capabilities of the FARSITE fire area simulator have been expanded to include post-frontal combustion and smoke production. FARSITE previously simulated only fire growth, with the focus on the fire perimeter. The BURNUP model was adapted to account for smoldering and…

Biomass burning is a major source of many atmospheric trace gases and aerosol particles (Crutzen and Andreae 1990). These compounds and particulates affect public health, regional air quality, air chemistry, and global climate. It is difficult to assess quantitatively the impact…

The emission of mercury from biomass burning was investigated in laboratory experiments and the results confirmed in airborne measurements on a wildfire near Hearst, Ont. Mercury contained in vegetation (live, dead, coniferous, deciduous) was essentially completely released in…

We measured stable and reactive trace gases with an airborne Fourier transform infrared spectrometer (AFTIR) on the University of Washington Convair-580 research aircraft in August/September 2000 during the SAFARI 2000 dry season campaign in Southern Africa. The measurements…

Many areas of the boreal forest of Alaska contain deep layers of moss, duff, and peat, resulting in a large pool of biomass that can potentially can burn and smolder for long periods of time creating hazardous smoke episode for local residents and communities and causing…

We adopt a working definition of residual smoldering combustion (RSC) as biomass combustion that produces emissions that are not lofted by strong fire-induced convection. RSC emissions can be produced for up to several weeks after the passage of a flame front and they are mostly…

Domestic biomass fuels (biofuels) were recently estimated to be the second largest source of carbon emissions from global biomass burning. Wood and charcoal provide approximately 90% and 10% of domestic energy in tropical Africa. In September 2000, we used open-path Fourier…

Smoke from wildland fires releases dramatic amounts of PM, CO, SO2, NOx, VOC and other chemical species. Meanwhile, high level of O3 can build up as a result of the emissions. These air pollutants can cause serious consequence to regional and local air quality by reducing…
