The role of black carbon (BC) soot in the Arctic as an agent of climate warming through forcing/feedback of sea ice/glacier albedo is an uncertainty in need of addressing. In-situ measurements of BC-aerosols and gas byproducts from the FROSTFIRE experiment burn, 8-11 July 1999,…

In Sept. 2003, a prescribed burn on the Uinta National Forest escaped, costing nearly $3 million to extinguish while choking Utah cities with smoke for a week. When the incident drew harsh criticism from local officials and news media, fire managers worried that prescribed…

Previous studies of the effects of heating on soil hydrophobicity have been conducted under free availability of oxygen. Under fire, however, soils may be deprived of oxygen due to its consumption at the heat source and inadequate replenishment in the soil. In the present study…

Above-ground biomass (live + dead), was estimated pre- and post-burn in eight types of savanna ecosystem in Roraima, in the extreme northern part of the Brazilian Amazon. The objective was to investigate the stock of pre-burn above-ground carbon and its fate after experimental…

The classification of savanna fires into headfire and backfire types can in theory help in assessing pollutant emissions to the atmosphere via relative apportionment of the amounts of smouldering and flaming combustion occurring, and is also important when assessing a fire's…

The production of residual white ash patches within wildfires represents near-complete combustion of the available fuel and releases a considerable quantity of gases to the atmosphere. These patches are generally produced from combustion of large downed woody debris (LDWD) such…

There were large interannual variations in burned area in the boreal region (ranging between 3.0 and 23.6x106 ha yr-1) for the period of 1992 and 1995-2003 which resulted in corresponding variations in total carbon and carbon monoxide emissions. We estimated a range of carbon…

From introduction: Wildfire is a majoar natural disaster in the United States. In 2002, for example, tens of thousands of wildfires occurred that consumed nearly seven million acres of forest and other land cover (NIFC, 2003). Wildfires contribute to increasing atmospheric CO2…
