ozone layer

ozone layer

n.

A region of the upper atmosphere, 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

A region of the upper atmosphere containing relatively high levels of ozone, located mostly within the stratosphere, with the greatest concentrations occurring from about 15 to 30 km (10 to 19 mi) above the Earth's surface. The ozone absorbs large amounts of solar ultraviolet radiation, preventing it from reaching the Earth's surface. The concentration of ozone in the ozone layer is usually under 10 parts per million. Also called ozonosphere. See Note at ozone.
