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).

Certainly, everyone wants to breathe cleaner air and to protect the ozone layer.
Yet another warned that unless something was done to fix the ozone layer.
HFCs have become popular substitutes for ozone-depleting substances, but while they are far better for the ozone layer they are also potent greenhouse gases, which means they contribute to global climate change.
Observations show that the hole -- formed as a result of depletion of the crucial, radiation-shielding ozone layer -- was spread across an area of 10.
In 1994, the UN General Assembly proclaimed 16 September the International Day for the Preservation of the Ozone Layer, commemorating the date of the signing, in 1987, of the Montreal Protocol on Substances that Deplete the Ozone Layer (resolution 49/114).
Marking the International Day for the Preservation of the Ozone Layer, which is celebrated on September 16 every year, he commended global efforts to protect the ozone layer from depletion and work out a mechanism to ensure an environmentally sustainable industrial growth.
The ozone layer - part of Earth's atmosphere which absorbs most of the sun's harmful ultraviolet radiation - is not made of ozone entirely.
One year after they reached a landmark agreement (the Kigali Amendment) to phase down climate-warming hydrofluorocarbons (HFCs), the 197 developed and developing country parties to the Montreal Protocol on Substances that Deplete the Ozone Layer and the Vienna Convention for the Protection of the Ozone Layer met in Montreal, Canada, to enhance their efforts to protect the ozone layer and to mitigate climate change.
The Montreal Protocol, considered to be the most successful global environmental agreement setting out commitments by every country in the world to eliminate production and use of chemicals which damage the ozone layer.
In the stratosphere, roughly 7 to 25 miles above Earth's surface, the ozone layer acts like sunscreen, shielding the planet from potentially harmful ultraviolet radiation that can cause skin cancer and cataracts, suppress immune systems and also damage plants.
The event, observed on September 16, coincides this year with the 30th anniversary of the Montreal Protocol on Substances that Deplete the Ozone Layer and is held under the theme "We Are All Ozone Heroes".
