Intense arctic ozone depletion in the spring of 2011
Observations of record-breaking ozone depletion during the Arctic spring of 2011 were made at 76° N in Thule, Greenland. The ozone total column amount of 290 DU measured on 18 March 2011 is the lowest value from the 12-year observation record and represents an ozone depletion of up to 48% of a typic...
