These questions arise not as a local phenomenon but on a world scale which is seldom appreciated. Fire regimes prevail not only over huge areas in south-central Africa and Brazil, but also extend through North Africa--in the Sudan Zone especially--and no doubt also occur in the…

Biomass burning effects the African continent all year round. In the dry season there are widespread savannah fires, and there are always some domestic and agricultural fires. Here we present measurement of particulate black carbon, which is an unambiguous indicator of…

Wild and prescribed fires currently burn about 20,100 ha per year in Washington west of the Cascade Crest: prehistoric wildfires burned an estimated 19,200 ha per year. Modern burning consumes 38 g/m²/yr of fuel; the estimated prehistoric rate was 35 g/m²/yr over a 50-percent…

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…

The NOAA 12 advanced very high resolution radiometer detected extensive forest fires in boreal Siberia and northern Mongolia during April through October 1998, a year of extremely dry weather, in particular, in the Russian Far East. Analysis of the satellite data has been…

We used NOAA-AVHRR satellite imagery, biomass density maps, fuel consumption estimates, and a carbon emission factor to estimate the total carbon (C) emissions from the spring 1998 fires in tropical Mexico. All eight states in southeast Mexico were affected by the wildfires,…

In Florida, natural communities require periodic fires for maintenance of their ecological integrity. Because of public concerns, wildfires can no longer be allowed to perform this mandatory function so prescribed burning is essential to manage these plant and animal communities…
