Short summary

We have undertaken atmospheric iodine monoxide (IO) observations in the global marine boundary layer with a wide latitudinal coverage and sea surface temperature (SST) range. We conclude that atmospheric iodine is abundant over the Western Pacific warm pool, appearing as an iodine fountain, where ozone (O₃) minima occur. Our study also found negative correlations between IO and O₃ concentrations over IO maxima, which requires reconsideration of the initiation process of halogen activation.
