Short summary
Organic aerosol (OA) components account for 20–90 % of sub-micrometer aerosol mass and have a broad distribution of hygroscopicity. For the first time, the diurnal variation and size dependence of the hygroscopicity of OA were characterized for a forest in East Asia. The observed variation and dependence were assessed from the viewpoint of biogenic secondary organic aerosol formation, and they strongly affected the contribution of OA to the CCN number concentration.
