Severe 2011 ozone depletion assessed with 11 years of ozone, NO2, and OClO measurements at 80°N
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 Eureka. Ozone columns were...

| description | 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 Eureka. Ozone columns were lower than in any other year in the record, reaching minima of 237 DU and 247 DU in two datasets. The average NO2 column inside the vortex, measured at visible and UV wavelengths, was 46 ± 30% and 45 ± 27% lower in 2011 than the average NO2column from previous years. Ozone column loss was estimated from two ozone datasets, using a modeled passive ozone tracer. For 12–20 March 2011, the average ozone loss was 27% and 29% (99 DU and 108 DU). The largest percent ozone loss in the 11‐year record of 47% (250 DU and 251 DU) was observed on 5 April 2011.
Key Points
Unprecedented low ozone and NO2 columns were observed in 2011
Low ozone and NO2 columns are attributed to dynamics as well as chemistry
47% maximum column ozone loss observed, the largest loss in the 11‐year record |
