Short summary

We conducted the first field measurements of non-refractory fine aerosols (NR-PM_2.5) in a megacity of eastern China using a PM_2.5-ACSM along with a PM₁-ACSM measurement. Inter-comparisons demonstrated that the NR-PM_2.5 components can be characterized. Substantial mass fractions of aerosol species were observed in the size range of 1–2.5 μm, with sulfate and SOA being the two largest contributors. The impacts of aerosol water driven by secondary inorganic aerosols on SOA formation were explored.
