Short summary
The main sources of PM2.5 during the 2013–2014 winter period in Beijing were identified as soil dust, traffic emission, biomass combustion, industrial emission, and coal combustion. A red-alert haze was almost equally contributed by local traffic and transported coal combustion emissions from Beijing vicinities. This study emphasizes the role of weather condition in haze formation by building up stagnant condition that facilitates the transport of emissions from Beijing's neighboring cities.
