Short summary
Field measurements for trace-level chemical species in the gas and particulate phases were conducted at a rural site in westernmost Japan to better understand formation of secondary pollutants in transboundary air. A comparison of photochemical ages estimated by chemical clock with ozone concentrations or fractions of carboxylate in organic aerosol showed proportional relationships, and their slopes were 3.48 × 10−7 ppbv molecule−1 cm3 h−1 and 1.05 × 10−9 molecule−1 cm3 h−1, respectively.
