Emission of trace gases and aerosols from biomass burning

TLDR

A large body of information on emissions from various types of biomass burning has been accumulated over the past decade, largely from IGBP/IGAC research, but it has not been readily accessible because it is scattered across many publications and reported in different units and reference systems. We critically evaluated the available data and integrated them into a consistent format, presenting emission factors for many species from biomass fires and proposing estimates via extrapolation where data were missing. We derived global estimates of pyrogenic emissions for key species from different biomass burning types and compared them with inverse modeling results.

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.
