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

Estimating the open biomass burning emissions in central and eastern China from 2003 to 2015 based on satellite observation
Jian Wu,Shaofei Kong,Fangqi Wu,Yi Cheng,Shurui Zheng,Qin Yan,Huang Zheng,Guowei Yang,Mingming Zheng,Dantong Liu,Delong Zhao,Shihua Qi +11 more
TL;DR: In this article, the authors provided a state-of-the-art estimation of the pollutant emissions from open biomass burning (OBB) in Central and Eastern China (CEC) from 2003 to 2015, by adopting the satellite observation dataset and local biomass data.

Diagnosing spatial biases and uncertainties in global fire emissions inventories: Indonesia as regional case study
Tianjia Liu,Loretta J. Mickley,Miriam E. Marlier,Ruth DeFries,Firoz Khan,Mohd Talib Latif,Alexandra Karambelas +6 more
TL;DR: In this paper, the authors used Google Earth Engine to leverage 15 years of MODIS observations and 6 years of observations from the higher spatial resolution Visible Imaging Infrared Radiometer Suite (VIIRS) sensor to develop metrics to quantify five major sources of spatial bias or uncertainty in the inventories: (1) primary reliance on active fires versus burned area, (2) cloud/haze burden on the ability of satellites to “see” fires, (3) fragmentation of burned areas, (4) roughness in topography, and (5) small

Characterization and source identification of a fine particle episode in Finland
Jarkko V. Niemi,Heikki Tervahattu,Hanna Vehkamäki,Markku Kulmala,Tarja Koskentalo,Markus Sillanpää,Minna Rantamäki +6 more
TL;DR: A strong long-range transported (LRT) fine particle (PM 2.5 ) episode occurred from March 17-22, 2002 over large areas of Finland as discussed by the authors, where the proportion of sulphur-rich particles rose strongly during the episode and the relative weight percentage of potassium was unusually high in these particles.

Improved rice residue burning emissions estimates: Accounting for practice-specific emission factors in air pollution assessments of Vietnam.
TL;DR: This study synthesized field and laboratory studies from the literature on rice residue burning emission factors for PM2.5 in Vietnam to highlight locations where emission mitigation efforts could be focused and suggest measures for pollutant mitigation.

Evaluating spectral indices for burned area discrimination using MODIS/ASTER (MASTER) airborne simulator data
TL;DR: In this article, high spatial and spectral resolution MODIS/ASTER (MASTER) airborne simulator data acquired over three 2007 southern California burns were used to evaluate the sensitivity of different spectral indices at discriminating burned land shortly after a 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.
