Title

Recent Arctic Ozone Depletion

Authors

Abstract

The Arctic stratospheric reductions in ozone in up to 38 percent were recorded in the winter of 2010-11. In the winter of 2015-16, there was yet another significant decline of 27 percent. The record low temperatures below TICE, a threshold of formation of the PSC polar stratosphere cloud persisted during the winter polar vortex for one month, an occurrence never seen before which caused the polar vortex to dehydrate/denitrify unprecedentedly. Chemistry-climate-modeling (CCMs) generally predict lower stratosphere cooling with an increase in greenhouse gas (GHG) atmospheric concentrations, although there are considerable variations between them which imply relative great uncertainty in predictions. A strong interpretation of the interaction in-between ozone depletion and stratospheric temperature is made of findings from (CTMs) chemical transport models. The great seasonal instability in the Arctic ensures, though, that major events of ozone loss like those of 2010-11 and 2015-16 will occur before the ozone-depleting material concentrations revert to their 1960s. It is possible, however, that the originally expected stratospheric ozone recovery in the mid-2030s will be postponed. The key cause of doubt in the existence of Arctic ozone was therefore the meteorological fluctuations and its possible development. To ensure that Arctic ozone recovers, high-quality soil-based measurements, including SAOZ (System of Study by Zénithale Observation) and satellite ozone column tests around the Arctic in winter and continuous modeling efforts, are necessary to evaluate and recognize trends in the coming decades.
