WebIt is estimated that one Chlorine atom can convert 100,000 molecules of Ozone into Oxygen before that chlorine becomes part of a less reactive compound, such as HCl, and eventually is precipitated out of the stratosphere by water vapor. For more information, see CFC-Ozone chemistry or Chlorofluorcarbons. Current Goverment regulations 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.
