We have analyzed the soluble portion of impurities trapped in solid precipitation that accumulated at Summit (central Greenland) from 1193 A.D. to the present. Seventy-three ice layers show elevated concentrations of ammonium and formate, caused by high-latitude biomass burning…

We assessed the exposure of rural residents in the small community of Theobroma, Brazil, to the smoke generated from widespread agricultural and forest burning during August and September, 1995. Samples were collected for an 8-day period by using five battery powered personal…

Investigations of the ecological, atmospheric chemical, and climatic impacts of contemporary fires in tropical vegetation have received increasing attention during the last 10 years. Little is known, however, about the impacts of climate changes on tropical vegetation and…

Within the Proteaceae, 353 species confined to 7 genera in the Grevilleoideae have woody fruits. The majority (> 70%) occur in fire-prone vegetation on nutrient-poor, summer-dry soils of south-western Australia. These species are characterised by large, winged seeds contained…

Smoke from forest fires in southern Mexico was advected into the U.S. southern plains from April to June 1998. Cloud-to-ground lightning (CG) flash data from the National Lightning Detection Network matched against satellite-mapped aerosol plumes imply that thunderstorms forming…

Burning of slashed tropical forests and pastures is among the most significant global sources of atmospheric emissions, yet the composition of the fuels and fires that creates these emissions is not well characterized. As part of the Smoke, Clouds, and Radiation-Brazil (SCAR-B)…

Boreal peatlands occupy about 1.14 x 106 km2 in North America. Fires can spread into peatlands, burning the biomass, and if moisture conditions permit, burning into the surface peat. Charred layers in peat sections reveal that historically bogs in the subhumid continental…

Boreal forests and woodlands comprise about 29% of the world's forest cover. About 70% of this forest is in Eurasia, mostly in the Russian Federation. Boreal forests contain about 45% of the world's growing stock and are an increasingly important part of global timber production…

A large forest fire occurred about 300 km to the northeast of the Edmonton area in early summer 1995. The forest fire produced nitrogen oxides, hydrocarbons and ozone which were transported down-wind. Continuous monitoring of O3, NO and NO2 and integrated measurements of…

Despite increasing temperatures since the end of the Little Ice Age (ca. 1850), wildfire frequency has decreased as shown in many field studies from North America and Europe. We believe that global warming since 1850 may have triggered decreases in fire frequency in some regions…

Fires in tropical savannas are a principal source of emissions to the atmosphere, but there are few studies of retention in ash and residual plant mass following natural fires. Estimates of carbon and nitrogen emissions to the atmosphere from biomass burning have relied largely…
