WebDefinition and methodology. Ozone (O 3) is a naturally occurring gas found in the stratosphere, 20–25 kilometres above Earth, in what is known as the ozone layer. The ozone hole is an area of reduced ozone (below 220 Dobson units (DU)) that forms over Antarctica. In winter, low temperatures over Antarctica form polar stratospheric clouds. Web4 jan. 2024 · The study was published Jan. 4 in the journal Geophysical Research Letters. The Antarctic ozone hole forms during September in the Southern Hemisphere’s winter as the returning sun’s rays catalyze ozone destruction cycles involving chlorine and bromine that come primarily from CFCs. Web10 nov. 2024 · Satellites showed that the ozone hole extended over a vast region of 20 million square kilometres. Researchers quickly agreed that compounds called CFCs, often used in aerosol cans and cooling devices such as fridges, must be responsible. The ozone layer above the Antarctic is especially sensitive to CFCs because of its unique geography. established 1962 dresses for women
