We review the 2012 Antarctic ozone hole, making use of various meteorological reanalyses, remotely sensed ozone measurements and ground-based measurements of ultra-violet radiation. Based on analysis of 33 years of satellite records, we find that the ozone hole of 2012 was one of the least severe since the late 1980s in terms of maximum area, minimum ozone level and total ozone deficit. In particular, the estimated integrated ozone mass effectively depleted within the ozone hole of 2012 was approximately 720 Mt, which is the 12th smallest deficit on record and 28 per cent of the peak deficit observed in 2006. The key factor in limiting the extent of Antarctic ozone loss in 2012 was the relat..View full abstract
