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

Satellite detection of a continental-scale plume of nitrogen oxides from boreal forest fires.
TL;DR: This paper used dispersion model calculations, Total Ozone Mapping Spectrometer (TOMS) aerosol index data, and tropospheric NO 2 columns derived from Global Ozone Monitoring Experiment (GOME) data to track a NO x plume from forest fire hot spots, via the Atlantic Ocean, to the west coast of Europe.

Airborne measurements indicate large methane emissions from the eastern Amazon basin
John B. Miller,John B. Miller,Luciana V. Gatti,M. T. S. D’Amelio,A. M. Crotwell,A. M. Crotwell,Edward J. Dlugokencky,Peter S. Bakwin,Paulo Artaxo,Pieter P. Tans +9 more
TL;DR: Miller et al. as mentioned in this paper presented regionally integrative, direct trace gas observations from two sites that confirm the presence of large fluxes of methane in eastern Amazonia, and calculated emissions averaging 27 mg CH4/m 2 /day from upwind sources.

Influence of biomass burning during recent fluctuations in the slow growth of global tropospheric methane
TL;DR: In this paper, a complementary measurement of other compounds (ethane, tetrachloroethene) was used to confirm the influence of biomass burning on large global CH4 pulses in 1998 and 2002-2003.

Contribution of garbage burning to chloride and PM 2.5 in Mexico City
TL;DR: The contribution of garbage burning (GB) emissions to chloride and PM2.5 in the Mexico City metropolitan area (MCMA) has been investigated for the period of 24 to 29 March during the MILAGRO-2006 campaign using the WRF-CHEM model as discussed by the authors.

New Analytical Method for the Determination of Levoglucosan, Polyhydroxy Compounds, and 2-Methylerythritol and Its Application to Smoke and Rainwater Samples
TL;DR: A new chromatographic method for the determination of levoglucosan (a specific tracer for biomass burning particles), related polyhydroxy compounds, and 2-methylerythritol (recently identified as isoprene oxidation product in fine aerosols in the Amazon) in smoke and in rainwater samples is developed.

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.
