Severe 2011 ozone depletion assessed with 11 years of ozone, NO 2 , and OClO measurements at 80°N
International audience Unusually cold conditions in Arctic winter 2010/11 led to large stratospheric ozone loss. We investigate this with UV-visible measurements made at Eureka, Canada (80.05°N, 86.42°W) from 1999-2011. For 8-22 March 2011, OClO was enhanced, indicating chlorine activation above Eur...
