Conference proceedings 1997 renowned experts from paleoecology, fire ecology, atmospheric chemistry, and organic chemistry, the volume elucidates the role of fire during global changes of the past and future. Topics covered include: the characterization of combustion products that occur in sediments, including char, soot/fly

The Sedimentary Record of Fire in Montane Meadows, Sierra Nevada, California, USA: a Preliminary Ass modeled data suggest that the early Holocene was xerothermic in the Sierra Nevada. Pollen evidence suggests forests were more open than today, thus producing less tree biomass for fuel. Intensification of El Ni?o during the middle Holocene may have been important in changing the character of the Sierran forests as well.

An Introduction to Sediment Records of Biomass Burninged on biomass burning (Crutzen and Goldammer 1993). That workshop together with subsequent discussions identified key challenges that require multidisciplinary efforts i) to better characterize combustion products that occur in sediments, including char, soot/fly ash, and polycyclic aromatic hydroca

Polycyclic Aromatic Hydrocarbons in Sedimentary Records of Biomass Burningn during long-range environmental transport. During the past century there has been a large increase in sedimentary PAH derived from fossil fuel combustion. The latter qualitatively produces PAH distributions similar to biomass burning. The use of new techniques, such as compound-specific isotope an

Biomass Burning Emissions and the Atmosphereids and aldehydes to waxes and tars. Results from biomass fires in the Canadian boreal system indicate average ratios of OC/EC of about 16:1 (Mazurek et al. 1991), from Africa of about 10:1 (Cachier et al. 1991), and from Brazil about 12:1 (Ward et al. 1992). Vegetation fires also produce charcoal c

Atmospheric Transports of Particulate and Gaseous Products by Fires; the synoptic or storm scales typical of a frontal cyclone with space scales between 100 – 1000 km and time scales of tens of minutes to less than 24 hours, and finally, the turbulent and smaller scales of motion which operate on space scales of much less than 1 km and time scales of minutes to mic
