ABSTRACT
Open biomass-burning (BB) occurs particularly during the dry season in the northern peninsular Southeast Asia (PSEA; here defined as Myanmar, Laos, Thailand, Vietnam, and Cambodia) due to slash-and-burn agricultural activities almost every year with varying intensities and emits huge amounts of trace gases and finer aerosols into the atmosphere. Several recent studies emphasized the BB emissions from the northern region of PSEA and explained their impacts on regional air quality, atmospheric radiation, and regional climate by using in situ ground-based measurements, satellite observations, remote-sensing datasets, and modeling studies within the Seven South East Asian Studies (7-SEAS) framework. This chapter presents an overview of BB emissions and their impacts on surface chemistry, aerosol optical properties, radiation budget, and public health over northern PSEA and downwind regions.
