Ozone loss in the polar regions is driven by halogen catalytic loss cycles. Central to the large ozone losses experienced every polar spring is the ClO dimer cycle. The recent ClOOCl photolysis cross-section measured by Pope et al. questions the role of this ClOOCl cycle in these large ozone losses.
