Abstract: On 16 September 1987, the main chlorofluorocarbon-producing and -consuming countries signed the Montreal Protocol, despite the absence of a scientific consensus on the mechanisms of ozone depletion over Antarctica. We argue in this article that… read more here.

Abstract: In the 1980s, British Antarctic scientists (Farman et al. 1985) discovered the hole in the ozone layer over Antarctica, and we are now familiar with images of springtime ozone depletion extending beyond the continental margins… read more here.

DOI: 10.1038/s41467-021-26109-x
Abstract: 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. The effects of the ozone hole and the associated… read more here.

DOI: 10.1073/pnas.2110864119
Abstract: 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… read more here.

DOI: 10.5194/acp-2020-1297
Abstract: Abstract. Without the Montreal Protocol the already extreme Arctic ozone losses in boreal spring of 2020 would be expected to have produced an Antarctic-like ozone hole, with an area of total ozone below 220 DU of… read more here.

DOI: 10.5194/angeo-2019-104
Abstract: Abstract. The purpose of this paper is to show how atmospheric dynamics behave during the occurrence of ozone-hole inflow events in Antarctica, especially in mid-latitude regions, such as southern Brazil, for 12 years of observation.… read more here.
