Southeast Asia is one of the biggest regions of biomass burning with forest fires and slash-and-burn farming. From the
fire events, a large amount of air pollutants are emitted such as carbon monoxide (CO), nitrogen oxide (NOx) and aerosol (black carbon; BC). Biomass burning generally causes not only local, but also transboundary air pollution, and
influences the atmospheric environment in the world accordingly. However, impact of air pollutants’ emissions from
large-scale fire in Southeast Asia is not well investigated compared to other regions such as South America and Africa.
In this study, characteristics of the atmospheric environment were investigated with correlative analyses among several
satellite data (MOPITT, OMI, and MODIS) and emission inventory (GFEDv3) in Southeast Asia from October 2004 to
June 2008 on a monthly basis. As a result, it is suggested that the transboundary air pollution from the biomass burning
regions occurred over Southeast Asia, which caused specifically higher air pollutants’ concentration at Hanoi, Vietnam
in spring dry season.
