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

Emission of Air Pollutants from Crop Residue Burning in India
TL;DR: In this article, a state-wise inventory of crop residue burnt in India and the air pollutants emitted was prepared using the Inter-Governmental Panel on Climate Change (IPCC) national inventory preparation guidelines for the year 2008-09.
Journal ArticleDOI
Assessing Methane Emissions from Global Space-Borne Observations
TL;DR: This work retrieved the global methane distribution by using spaceborne near-infrared absorption spectroscopy and observed unexpectedly high methane concentrations over tropical rainforests, revealing that emission inventories considerably underestimated methane sources in these regions during the time period of investigation.

Quantifying the uncertainties of a bottom-up emission inventory of anthropogenic atmospheric pollutants in China
TL;DR: In this paper, the uncertainties of Chinese emissions of anthropogenic SO2, NOx, and particulate matter (PM) of different size classes and carbonaceous species are comprehensively quantified, for the first time, using Monte Carlo simulation.

Individual aerosol particles from biomass burning in southern Africa: 1. Compositions and size distributions of carbonaceous particles
TL;DR: In this article, individual aerosol particles in smoke plumes from biomass fires and in regional hazes in southern Africa were studied using analytical transmission electron microscopy (TEM), which allowed detailed characterization of carbonaceous particle types in smoke and determination of changes in particle properties and concentrations during smoke aging.

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.
