Abstract Unlike bromine, the effect of iodine chemistry on Arctic surface ozone budget is poorly constrained. We present ship-based measurements halogen oxides in high boundary layer from sunlit period March to October 2020 and show that enhances springtime tropospheric depletion. find chemical reactions between are second highest contributor loss over study period, after photolysis-initiated ahead bromine.
