Short summary

The research apportions size-resolved aerosol contributions from the South China Sea during the Vasco research cruise in September 2011. As aerosols can affect precipitation rates and cloud formation, identifying sources is key to characterizing the region and developing our understanding of aerosol–cloud behavior. A strong biomass burning signal was identified using elemental particulate matter in the fine and ultrafine size ranges. Oil combustion, soil dust, and sea spray were also identified.
