Short summary
Chemistry-transport models have predicted a change in secondary organic aerosols (SOA) in the future atmosphere with a large uncertainty. This study measures diacids, major water-soluble surrogates of SOA, on a sub-decadal scale in atmospheric aerosols in eastern Asia. Diacids are observed to increase by 3.9–47.4 % per year. The increases in the water-soluble organic acid fraction could modify the aerosol organic composition and its sensitivity to climate-relevant physical properties.
