Measurements in the plumes from seven forest fires show that the concentrations of NH3 were considerably in excess of ambient values. Calculation of NH3 emissions from the fires, based on the ratio of NH3/CO in the plumes and emissions of CO from biomass burning, suggest that…

Smoke aerosol was collected on filters from a helicopter during a 400-acre (1.62 km2) prescribed chaparral burn in the San Dimas Experimental Forest on December 12, 1986. Hi-Vol samplers were used to collect particles on both Teflon and glass fiber filters. Scanning electron…

Gas samples were collected in smoke plumes over the San Dimas Experimental Forest during a 400-acre prescribed chaparral fire on December 12, 1986. A helicopter was used to collect gas samples over areas of vigorous flaming combustion and over areas of mixed stages (vigorous/…

Recent measurements indicate significantly enhanced biogenic soil emissions of both nitric oxide (NO) and nitrous oxide (N2O) following surface burning. These enhanced fluxes persisted for at least 6 months following the burn. Simultaneous measurements indicate enhanced levels…

Emission reduction is a central part of the regulatory strategy for prescribed forest burning in Washington and Oregon. This paper examines the success of that strategy and the information systems needed to plan and tract progress toward emission reduction goals specified in the…

Emission factors and the size distribution for smoke particles from prescribed fire are described from data collected by airborne sampling, surface sampling using towers, and combustion hood systems. Emission factors for particulate matter (g/kg) range from 4 to 16 for particles…

Smoke emitted from forest fires in northern California in September 1987 was trapped in a valley by an inversion for 3 weeks. Daily maximum temperatures on the valley floor were more than 15 degrees C below normal for 1 week and more than 5 degrees C below normal for 3 weeks.…

Greater needle packing (number of needles per unit stem length) among shoots of Picea engelmanii(Parry ex. Engelm.), Abies lasiocarpa ([Hook] Nutt.), and Pinus contorta (Engelm.) collected at sun-exposed locations resulted in leaf temperatures (T1) that were well above air…

[Annotation copied from Lynham et al. 2002(https://www.frames.gov/rcs/18000/18093.html)] Jack pine (Pinus banksiana) is an economically important Canadian tree species and its autecology is inextricably linked to fire. It would disappear as a natural component of the boreal…

Fire links the biosphere and the atmosphere. The linkage is, as yet, poorly quantified. Evidence suggests that a few percent of total C fixed by photosynthesis is oxidized by burning. Biomass burning seems to be globally significant in terms of associated: • Releases of trace…
