ozone layer

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.

o′zone lay`er

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).
