Because ozone in the upper atmosphere absorbs heat radiating from below, stratospheric ozone depletion actually allows additional heat to escape into space.
This was rectified in 1963 by the Australian physicist Stuart Thomas Butler and his student K.A. Small who showed that stratospheric ozone absorbs an even greater part of the solar insolation.
Firstly, the ozone absorbs solar ultraviolet radiation in the UV-B or 280-320 nm wavelengths, thus warming the stratosphere and producing a steep temperature inversion between 15 and 50 km.
The Dobson unit is a measure of how ozone absorbs several different wavelengths of sunlight.
The ozone then absorbs dangerous ultraviolet radiation.
In the stratosphere, ozone, a form of oxygen, absorbs most of the ultraviolet radiation from the sun, which can cause sunburn and skin cancer and which can be lethal to many life forms.
The largest-amplitude atmospheric tides are mostly generated in the troposphere and stratosphere when the atmosphere is periodically heated, as water vapour and ozone absorb solar radiation during the day.
Because ozone in the stratosphere strongly absorbs energy in the UV-B portion of the solar spectrum (280 to 320 nm), any changes in the total amount of ozone affect the levels of UV-B radiation reaching the ground.
Atmospheric ozone absorbs the sun's ultraviolet rays, which are believed to cause gene mutations, skin cancer, and cataracts in humans.
The ozone in this layer absorbs ultraviolet radiation from the sun, preventing a portion of the radiation from reaching the earth's surface where it can be harmful to plants and animals.
