Short summary
Size-segregated aerosols in nine size bins were collected in spring 2008 at Cape Hedo, Okinawa, in the western North Pacific Rim, and measured for diacids and related polar compounds. Oxalic acid, glyoxylic acid, and glyoxal peaked at 0.65–1.1 µm in fine mode, suggesting their secondary formation possibly in aerosol aqueous phase. Their strong correlations with liquid water content in fine mode further suggest an importance of the aqueous-phase production in Okinawa aerosols.
