Ozone gas is continuously formed by the action of UV rays on elementary oxygen and also degraded into molecular oxygen in the stratosphere.

The thickness of the ozone in a column of air from the ground to the top of the atmosphere is measured in terms of Dobson units.

Cl degrades ozone releasing molecular oxygen, with these atoms acting merely as catalysts.

Although ozone depletion is occurring widely in the stratosphere, the depletion is particularly marked over the Antarctic region.
