TLDR
In this article, the authors present a set of emission factors for a large variety of species emitted from biomass fires, where data were not available, they have proposed estimates based on appropriate extrapolation techniques.Abstract:
A large body of information on emissions from the various types of biomass burning has been accumulated over the past decade, to a large extent as a result of International Geosphere-Biosphere Programme/International Global Atmospheric Chemistry research activities. Yet this information has not been readily accessible to the atmospheric chemistry community because it was scattered over a large number of publications and reported in numerous different units and reference systems. We have critically evaluated the presently available data and integrated these into a consistent format. On the basis of this analysis we present a set of emission factors for a large variety of species emitted from biomass fires. Where data were not available, we have proposed estimates based on appropriate extrapolation techniques. We have derived global estimates of pyrogenic emissions for important species emitted by the various types of biomass burning and compared our estimates with results from inverse modeling studies.read more

Chemical characteristics and source apportionment of PM2.5 during the harvest season in eastern China's agricultural regions
TL;DR: In this article, the contribution of the open burning of wheat straw residues to local PM2.5 was determined, including two types of wheat residue burning sources, which showed a significant difference in Cl− content.

TL;DR: It is found that the most distinctive markers of PM sources in Warsaw are SOC, Cl- and As for residential combustion, NH4+, Sb and POC for road transport, Ca and Mg for construction works and SO42- for long-range transport of PM.

Mapping burn severity and burning efficiency in California using simulation models and Landsat imagery
TL;DR: In this article, a burn severity map of two large fires in California was obtained by inverting a simulation model constrained by post-fire observations from Landsat TM imagery, which was then used to adjust BE reference values per vegetation type found in the area before the fire.

Biomass Burning in the Tropics: Impact on Atmospheric Chemistry and Biogeochemical Cycles
TL;DR: Widespread burning of biomass serves to clear land for shifting cultivation, to convert forests to agricultural and pastoral lands, and to remove dry vegetation in order to promote agricultural productivity and the growth of higher yield grasses, but it may also disturb biogeochemical cycles, especially that of nitrogen.

Estimates of gross and net fluxes of carbon between the biosphere and the atmosphere from biomass burning
Wolfgang Seiler,Paul J. Crutzen +1 more
TL;DR: In this paper, the authors estimated the global amounts of biomass which are affected by fires, and estimated an overall effect lof the biosphere on the atmospheric carbon dioxide budget which may range between the possibilities of a net uptake or a net release of about 2 Pg C/yr.

Biomass burning as a source of atmospheric gases CO, H 2 , N 2 O, NO, CH 3 Cl and COS
Paul J. Crutzen,Leroy E. Heidt,Joseph P. Krasnec,W. H. Pollock,Wolfgang Seiler,Wolfgang Seiler +5 more
TL;DR: In this article, it was shown that most biomass burning takes place in the tropics in the dry season and is caused by man's activities, which can contribute extensively to the budgets of several gases which are important in atmospheric chemistry.

Soot Carbon and Excess Fine Potassium: Long-Range Transport of Combustion-Derived Aerosols
TL;DR: During a cruise from Hamburg to Montevideo, aerosol samples representing air masses from Europe, the Sahara, tropical Africa, South America, and open oceanic regions were collected and the ratio of soot carbon to fine carbon suggests that most of the particulate organic carbon over the Atlantic is of continental origin.
Global biomass burning: atmospheric, climatic, and biospheric implications.
TL;DR: The 1990 American Geophysical Union's Conference on Biochemical burning as discussed by the authors was attended by more than 175 participants representing 19 countries and discussed remote sensing data concerning biomass burning, gaseous and particle emissions resulting from BB in the tropics, BB in temperate and boreal ecosystems, the historic and prehistoric perspectives on BB, BB and global budgets for carbon, nitrogen, and oxygen, and the BB and the greenhouse effect.
