Airborne measurements of 13 trace gases from seven forest fires in North America are used to determine their average emission factors. The emission factors are then used to estimate the contributions of biomass ubrning to the worldwide fluxes of these...

[from the text] Outdoor recreation is continuing to increase in the United States. Hendee et al. (1977) estimated that public use of wilderness areas will increase, in the 40-year period from 1960 to 2000, by nearly tenfold. A report by the Heritage...

The Ontario Ministry of Environment (MOE) recently participated in a joint Canadian/U.S. program to monitor the behavior and environmental impact of prescribed fires. Air, soil and ash samples were collected at the burn sites and analyzed for...

To demonstrate the usefulness of active remote-sensing systems in observing forest fire plume behavior, we studied two fires, one using a 3.2-cm-wavelength Doppler radar, and one more extensively, using Doppler lidar. Both instruments observed the...

Biomass and hydrocarbon fuel fires are two common sources of obscuring smoke which present significant operational challenges over a broad range of possible viewing wavelengths. This is especially true of very large fires where the primary smoke...

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...
