Ozone layer From Wikipedia, the free encyclopedia Jump to: navigation search The ozone layer is a layer in Earth's atmosphere which contains relatively high concentrations of ozone (O ). This layer absorbs 97-99% of the sun 's high frequency ultraviolet light , which is potentially damaging to life on Earth. Over 90% of ozone in earth's atmosphere is present here. "Relatively high" means a few parts per million—much higher than the concentrations in the lower atmosphere but still small compared to the main components of the atmosphere. It is mainly located in the lower portion of the stratosphere from approximately 15 km to 35 km above Earth's surface, though the thickness varies seasonally and geographically. The ozone layer was discovered in 1913 by the French physicists Charles Fabry and Henri Buisson . Its properties were explored in detail by the British meteorologist G. M. B. Dobson , who developed a simple spectrophotometer that could be used to measure stratospheric ozone from the ground. Between 1928 and 1958 Dobson established a worldwide network of ozone monitoring stations which continues to operate today. The " Dobson unit ", a convenient measure of the total amount of ozone in a column overhead, is named in his honor.

Important legal notice document.write(''); document.write('English (en)'); document.write(' '); en EUROPA European Commission Environment Climate Change ... Resources ajaxinclude("scripts/menu.htm") Protection of the ozone layer The ozone layer Although ozone (O ) is present in small concentrations throughout the atmosphere, most ozone (about 90%) exists in the stratosphere, in a layer between 10 and 50km above the surface of the earth. This ozone layer performs the essential task of filtering out most of the sun's biologically harmful ultraviolet (UV-B) radiation. Concentrations of ozone in the atmosphere vary naturally according to temperature, weather, latitude and altitude. Furthermore, aerosols and other particles ejected by natural events such as volcanic eruptions can have measurable impacts on ozone levels. The Ozone Hole In 1985, scientists identified a thinning of the ozone layer over the Antarctic during the spring months which became known as the "ozone hole". The scientific evidence shows that human-made chemicals are responsible for the creation of the Antarctic ozone hole and are also likely to play a role in global ozone losses. Ozone Depleting Substances (ODS) have been used in many products which take advantage of their physical properties (e.g. chlorofluorocarbons (CFCs) have been used as aerosol propellants and refrigerants).

Mr. Ozone Layer do do I know all this you ask? Well, I'll tell you, I met them, yup was abducted and they told me the whole story and said if I helped them they would spare me and my family and friends and anyone wearing one of my Mr. Ozone T-Shirts. They liked the T-Shirts eh, took a whole whack of em back home to the Pod. They figured anyone saavy enough to understand the condition our condition was in deserved to be spared.They were really very nice folks, they just don't liked to frigged with and they figured they would be doing us a favour- sort of help clean things up a bit and give us a few more good years, but no cars, we can't have anymore cars. Besides they are taking all the nice cars with them, leaving the Ladas though. They have some kind of super weapon that only vaporizes specific people and things, the Mr. Ozone T-Shirts have been impinted with a special symbol that protects them. Cool eh? What's really cool though is that they said anyone starving to death because of all the inequality in the use of the earths resources and any indigenous peoples would also be spared, and they don't even have to have a T-Shirt! I don't know how they are going to do that but I liked it and guess thats why I really liked them so much. So if I were you I would be getting myself one of those T-Shirts! - Get A T-Shirt.

The Ozone Layer and CFCs How does the ozone layer normally work? At all times, the concentration of oxygen (O ) far exceeds that of ozone (O ) in the atmosphere. Ultraviolet (UV) light with wavelengths between 240 and 320 nm is absorbed by O , which then falls apart to give an O atom and an O molecule. The O atom soon encounters another O molecule, however, and recreates O as shown here: O + O O + O Thus ozone absorbs UV radiation without itself being consumed; the net result is to convert damaging UV light into heat. Indeed, this is what causes the temperature of the stratosphere to increase with altitude, giving rise to the inversion layer that traps molecules in the troposphere. The ozone layer isn't just in the stratosphere; the ozone layer actually determines the form of the stratosphere. Ozone is destroyed if an O atom and an O molecule meet; this is called recombination. O + O This reaction is slow, however, and if it were the only mechanism for ozone loss, the ozone layer would be about twice as thick as it is. Certain trace species, such as the oxides of Nitrogen (NO and NO ), Hydrogen (H, OH, and HO
