Short summary

In east Asia, emissions of O3 precursors have gradually increased and O3 concentrations are expected to increase in the near future. Ieodo Ocean Research Station (IORS), located in the East China Sea, is a unique research tower suitable for observing continental outflows from east Asia. In this study, we present long-term measurements of O3 at IORS, describe their characteristic variations, and evaluate their continental influence on the regional background concentrations of O3.
