Delay in recovery of the Antarctic ozone hole from unexpected CFC-11 emissions [PDF]

open access: yesNature Communications, 2019
The Antarctic ozone hole is decreasing in size due to policies implemented following the Montreal Protocol. Here, model simulations show that if recently discovered increase in unreported CFC-11 emissions continue, they could delay the recovery of the ...

The Antarctic ozone hole and the pattern effect on climate sensitivity. [PDF]

open access: yesProc Natl Acad Sci U S A, 2022
Significance We provide a perspective on recent scientific literature that argues the reduction in climate sensitivity identified with relative cooling in the eastern tropical Pacific Ocean could be caused by the onset of the Antarctic ozone hole ...

The influence of iodine on the Antarctic stratospheric ozone hole. [PDF]

open access: yesProc Natl Acad Sci U S A, 2022
Significance The role of chlorine and bromine in Antarctic stratospheric ozone depletion is well known. However, the contribution of iodine to the ozone hole chemistry has not been assessed, mainly due to the negligible amounts of iodine previously ...

Australian wildfires cause the largest stratospheric warming since Pinatubo and extends the lifetime of the Antarctic ozone hole. [PDF]

open access: yesSci Rep, 2022
Global mean lower stratosphere temperatures rose abruptly in January 2020 reaching values not experienced since the early 1990s. Anomalously high lower stratospheric temperatures were recorded for 4 months at highly statistically significant levels. Here,

Antarctic ozone hole modifies iodine geochemistry on the Antarctic Plateau. [PDF]

open access: yesNat Commun, 2021
Polar stratospheric ozone has decreased since the 1970s due to anthropogenic emissions of chlorofluorocarbons and halons, resulting in the formation of an ozone hole over Antarctica.

Fingerprints of the cosmic ray driven mechanism of the ozone hole [PDF]

open access: yesAIP Advances, 2021
There is long research interest in electron-induced reactions of halogenated molecules. It has been two decades since the cosmic-ray (CR) driven electron-induced reaction (CRE) mechanism for the ozone hole formation was proposed. The derived CRE equation

Brief communication "Stratospheric winds, transport barriers and the 2011 Arctic ozone hole" [PDF]

open access: yesNonlinear Processes in Geophysics, 2012
The Arctic stratosphere throughout the late winter and early spring of 2011 was characterized by an unusually severe ozone loss, resulting in what has been described as an ozone hole.

An Arctic ozone hole in 2020 if not for the Montreal Protocol [PDF]

open access: yesAtmospheric Chemistry and Physics, 2021
Without the Montreal Protocol, the already extreme Arctic ozone losses in the boreal spring of 2020 would be expected to have produced an Antarctic-like ozone hole, based upon simulations performed using the specified dynamics version of the Whole ...

The Antarctic ozone hole during 2015 and 2016 [PDF]

open access: yesJournal of Southern Hemisphere Earth Systems Science, 2019
We reviewed the 2015 and 2016 Antarctic ozone holes, making use of a variety of ground-based and spacebased measurements of ozone and ultraviolet radiation, supplemented by meteorological reanalyses.

The signs of Antarctic ozone hole recovery. [PDF]

open access: yesSci Rep, 2017
Absorption of solar radiation by stratospheric ozone affects atmospheric dynamics and chemistry, and sustains life on Earth by preventing harmful radiation from reaching the surface.
