Insufficient knowledge of air pollution sources in South Asia hinders the development of pollution mitigation strategies to protect public health (Gurung and Bell, 2013) and model representation of air quality and climate on local to global scales (Adhikary et al., 2007; Bond et al., 2013). Prevalent but under-characterized combustion emission sources in South Asia include traffic, brick kilns, garbage burning, cooking stoves, and the open burning of biomass. To begin to address this gap, the Nepal Ambient Monitoring and Source Testing Experiment (NAMaSTE) was conducted to characterize the emissions of gas and particle species produced by the many important combustion sources in Nepal as a model for South Asia, develop emission factors and detailed emissions profiles for these sources to support revisions to regional emissions inventories, and apply knowledge of source emissions to improve source apportionment of ambient air pollution.
