ozone layer

n.
A region of the atmosphere lying mostly in the stratosphere, between about 15 and 30 kilometers (10 and 20 miles) in altitude, containing a relatively high concentration of ozone that absorbs solar ultraviolet radiation in a wavelength range not screened by other atmospheric components. Also called ozonosphere.

ozone layer

n
(Physical Geography) the region of the stratosphere with the highest concentration of ozone molecules, which by absorbing high-energy solar ultraviolet radiation protects organisms on earth. Also called: ozonosphere

o′zone lay`er


n.
the layer of the upper atmosphere where most atmospheric ozone is concentrated, from about 8 to 30 mi. (12 to 48 km) above the earth.

ozone layer

A belt of ozone gas in the upper atmosphere. This ozone filters out incoming ultraviolet radiation liable to damage the chemicals all living things are made of. Holes appearing in the ozone layer above polar regions have been blamed on chlorofluorocarbons (CFCs).

The ultraviolet radiation spectrum has been divided into three types as a function of their wavelength range: (i) UVC, with a spectral range from 100 to 280 nm, which is completely absorbed by the stratospheric ozone layer, (ii) UVB, with a spectral range from 280 to 320 nm, which is mostly absorbed by the stratospheric ozone layer and virtually no solar radiation below 295 nm is incident on the earth's surface, (iii) UVA, with a spectral range from 320 to 400 nm, where stratospheric ozone layer absorption is minimal.
While stratospheric ozone provides vital protection against harmful solar radiation, the same gas in the lower troposphere is a man-made pollutant and harmful to health.
