Abstract

Biomass burning is now recognized as a major source of important trace gases, including CO2, NO2, CO and CH4, and of aerosol particles. It takes on many forms: burning of forested areas for land clearing, extensive burning of grasslands and savannas to sustain grazing lands, burning of harvest debris, and use of biomass fuel for heating. The emissions from biomass burning represent a large perturbation to global atmospheric chemistry, especially in the tropics. Here, satellite observations have shown high levels of 03 and CO over vast areas of Africa, South America, and the tropical Atlantic and Indian Oceans. Recent studies have linked this phenomenon to biomass burning plumes, and demonstrate that pyrogenic emissions affect regional ozone concentrations and the oxidative characteristics of the tropical atmosphere. The particulates affect regional global radiation budgets by their light-scattering effects and their influence on cloud microphysical processes.
