While the vast majority of carbon emitted by wildland fires is released as CO2, CO, and CH4, wildland fire smoke is nonetheless a rich and complex mixture of gases and aerosols. Primary emissions include significant amounts of CH4 and aerosol (organic...

Aerostat-lofted instrument and sampling method for determination of emissions from open area sources
An aerostat-borne instrument and sampling method was developed to characterize air samples from area sources, such as emissions from open burning. The 10 kg battery-powered instrument system, termed “the Flyer”, is lofted with a helium-filled aerostat...

This paper presents airborne measurements of multiple atmospheric trace constituents including greenhouse gases (such as CO2, CH4, O3) and biomass burning tracers (such as CO, CH3CN) downwind of an exceptionally large wildfire. In summer 2013, the Rim...

Frequent wildfires emit large amounts of black carbon (BC) into the atmosphere in the semiarid regions of the African continent. This atmospheric BC efficiently absorbs shortwave radiation and thus modifies the climate system on a regional scale....

Soil is an important reservoir of PCDD/PCDF, which can be released when environmental conditions change. Fire is an extreme event that can increase the surface temperatures of soil substantially, yet little is known of the role soil plays in the...

Emissions of trace gases and particulate matter from burning of biomass are generally factored into global climate models. Models for improving the estimates of the global annual release of emissions from biomass fires are presented. Estimates of total...

Emission factors for several trace gases were determined using airborne measurements from 13 biomass fires in North America. Emissions of methane (CH4), nonmethane hydrocarbons (NMHC), hydrogen (H2) and ammonia (NH3) were found to be positively...

Emissions of trace gases and C5-C10 volatile organic compounds (VOCs) from Mediterranean wildfires occurring in Portugal in summer 2010 were studied. Fire smoke was collected in Tedlar bags and analysed for CO, CO2, total hydrocarbons (THC) and VOCs....

Until recently, monitoring for emissions from open burning were limited principally to industrial pollutants, as governed by the National Ambient Air Quality Standards. Emission factors were determined by relating the quantity of effluent produced to...
