Smoke produced by vegetation fires consists of a complex mixture of gaseous, liquid, and solid phases. Many particulates are generated during vegetation fires. Crutzen and Andreae (1990) have estimated that global emissions of pyrogenic smoke particles (50-150 Tg yr-l) may…

A large forest fire occurred about 300 km to the northeast of the Edmonton area in early summer 1995. The forest fire produced nitrogen oxides, hydrocarbons and ozone which were transported down-wind. Continuous monitoring of O3, NO and NO2 and integrated measurements of…

Despite increasing temperatures since the end of the Little Ice Age (ca. 1850), wildfire frequency has decreased as shown in many field studies from North America and Europe. We believe that global warming since 1850 may have triggered decreases in fire frequency in some regions…

An overview is given of recent research on forest fires, particularly climate change and its implications for forest fire and vegetation zoning in Russian and Canadian boreal forests, fire emissions and their impact on the atmosphere, the predicted catastrophic effects on global…

Carbon emissions in fires in the boreal forests of Russia were calculated from data on the area burned, fire intensity, post-fire mortality and decomposition of fuels, and change in vegetation structure after fires. The actual area of boreal forests burned in Russia appears to…

1 Smoke-stimulated germination in the post-fire flora of California chaparral does not appear to be triggered by nitrate. Application of freshly prepared unbuffered KNO³ solutions (pH c. 6.2) failed to enhance germination of five populations of Emmenanthe penduliflora or one…

Global annual NO emissions from soil are of the order of 10 Tg NO-N. This is about half the amount fossil fuel combustion processes contribute to the annual global NOx budget. Reducing the emissions of soil derived NOx requires an understanding of the source of the flux and the…

Fires in tropical savannas are a principal source of emissions to the atmosphere, but there are few studies of retention in ash and residual plant mass following natural fires. Estimates of carbon and nitrogen emissions to the atmosphere from biomass burning have relied largely…
