The ozone layer is a layer with high ozone concentration in the stratosphere of the atmosphere The most concentrated part is located at an altitude of 20 25 kilometers If the ozone of the ozone layer is calibrated to the standard case its thickness is only about 3 mm on average Ozone content varies with latitude season and weather

Ozone depletion consists of two related events observed since the late 1970s a steady lowering of about four percent in the total amount of ozone in Earth s atmosphere and a much larger springtime decrease in stratospheric ozone the ozone layer around Earth s polar regions The latter phenomenon is referred to as the ozone hole There are also springtime polar tropospheric ozone depletion

Also the ozone depleting substances existing in banks and equipment need special attention to prevent their release to the stratosphere Since many of the ozone depleting substances already in the atmosphere are long lived recovery cannot be immediate and present projections estimate a return to pre 1980 levels by 2024 to 2024
