Short summary
Reactive iodine species play a key role in the oxidation capacity of the polar troposphere, although sources and mechanisms are poorly understood. In this paper, the photolysis of frozen iodate salt has been studied, confirming that under near-UV–Vis radiation iodate is photolysed. Incorporating this result into an Antarctic atmospheric model, we have shown that it could increase the atmospheric IO levels and could constitute a pathway for the release of active iodine to the polar atmosphere
