The discovery of the ozone hole over Antarctica in 1985 was a surprise for science. For a few years the reasons of the ozone hole was speculated about. Soon it was obvious that predominant meteorological conditions led to a specific situation developing in this part of the atmosphere: Very ...
This stalemate was finally resolved only after the discovery of the ozone hole over Antarctica and the irrefutable evidence linking the ozone hole to CFCs. Only then did the major manufacturers of CFCs begin to get on board. In the end, an international agreement was signed to control CFC ...
The British Antarctic Survey (BAS) research station has been gathering atmospheric data since 1956 – measurements from Halley led to the discovery of the hole in the ozone layer in 1985. It is located on the Brunt ice shelf, a floating slab of ice some 150 to 250 metres thick atta...
There were new developments in building research stations on the ice shelf, and the discovery of the ozone hole that gripped the world. Then followed the transition from research scientist to policy maker and diplomat when he became Deputy Director of BAS and advisor to the British delegation at...
More than three decades after the discovery of the ozone hole, the processes involved in its formation are believed to be understood in great detail. Current state-of-the-art models are able to reproduce the observed chemical composition in the springtime polar stratosphere, especially regarding the...
Ever since the discovery of the ozone hole over the Antarctic and the recognition of the damaging effects of acid rain, the role of atmospheric aerosol particles in determining the chemical balance of the atmosphere has received much attention. Aerosol particles produced in combustion can also have...
After a brief introduction to atmospheric chemistry and the history of CFCs, the first part of this paper narrates the history of that prediction, its experimental verification, including the discovery of the Ozone Hole, and the international political consequences. The second part investigates if ...
After the discovery of the Antarctic ozone hole in the 1980s1,2, numerous studies have focused on the future evolution of stratospheric ozone layer depletion given its relevance for life on Earth3. The Montreal Protocol, signed in 1987 with later amendments and adjustments, limits the production ...
Since the discovery of the ozone hole in the early 1980s, spatial ozone measurements have been widely used to evaluate and quantify the spatial extension of polar ozone depletion and global ozone decreasing trends as a function of latitude and height. Validation and evaluation of satellite ozone ...
What has been done about the production of chlorofluorocarbons (CFCs) since the discovery in 1987 of a hole in the ozone over Antarctica; How the problem if far graver than anyone thought; EPA's plans to intensify its efforts. INSET: Danger: ...
