Full latitudinal marine atmospheric measurements of iodine monoxide

31 March 2022

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