Main navigation Navigation within the topic Content Ozone Layer Atmospheric Ozone Monitoring The ozone layer is well known for its protective effect of life on earth's surface by screening the damaging solar UV radiation. It is therefore important to regularly monitor the amount of ozone around the globe. MeteoSwiss is regularily measuring the ozone present in the upper atmosphere above Switzerland with different instruments. MeteoSwiss ozone monitoring Updated on 03.04.2008, 18.00 large.gif, 10 KB Total ozone amount above Arosa The transparency of the atmosphere to the UV radiation from the sun is measured with spectrophotometers. From these measurements, the total amount of ozone contained in the column of atmosphere above the Arosa Observatory is calculated. In the figure to the left, the daily mean ozone is reported for the last 14 days.

The ozone is measured in situ and the data are transmitted to the Payerne station during the ascent. Such profiles are measured three times per week on Monday, Wednesday and Friday noon. In the figure on the left, the last valid ozone profile is presented.

Index A to Z You are here: home sciences International Day for the Preservation of the Ozone Layer September 16 A Nobel-worthy discovery In 1974, U.S. chemists Sherwood Rowland and Mario Molina were the first to sound the alarm. That year, they published the first scientific article predicting the near disappearance of the ozone layer in 75 years. They were remarkably prescient; in the early 1980s, a hole in the ozone layer was observed for the first time at the Earth's poles. And the numbers were frightening. Over the Antarctic, 70% of the protective gas had disappeared, while 30% had been depleted over the Arctic. Rowland and Sherwood won the Nobel Prize in chemistry in 1995 for their work in atmospheric chemistry. The illustration shows some layers of the atmosphere. The ozone layer, which protects us from harmful radiation, is part of the stratosphere. Ozone is highly corrosive and toxic and is used as a disinfectant. It can be found in small concentrations in the troposphere where it is considered a pollutant. Since then, a number of other countries have come on board, bringing the total number of signatory countries to 175.

Ozone Layer Key Facts Challenges Make A Difference Imagine that the Earth has a shade around it, protecting it from the heat of the sun. This is called the ozone layer. This layer has holes in it through which harmful rays get through. You have probably heard people talk about a "hole" in the ozone layer. Damage to our Earth's giant protective umbrella is more severe at the South Pole, but even there, no actual "hole" exists. Over the rest of the world this "umbrella" is becoming worn out, fragile and thin. But no matter where you stand, you won't find a true "hole". If you have ever noticed the "sharp" clean smell after a thunderstorm or the "electric" smell of a subway train, then you've smelled a bit of ozone gas. In large quantities, ozone is unpleasant. It has a strong odour that irritates the eyes and affects the lungs.

Get informed Ozone layer Fact Sheets The ozone layer and the greenhouse effect More information Atmospheric science Is the hole in the ozone layer something to do with the greenhouse effect? No, but people have had an effect just the same. Thinning of the ozone layer and global warming due to the greenhouse effect are sometimes thought to be one and the same problem. They are actually two entirely different, and serious, environmental problems. So, why is there a hole? In the past, people invented products that were very useful to humans, but not so useful to the ozone layer. These products, like aerosol cans for paint and hair spray, contained gases including CFCs that chewed up ozone and left people and animals exposed to unsafe levels of ultraviolet light, which can cause cancer and eye cataracts. Nowadays, controls are in place to stop these substances from eating up the ozone layer, so hopefully our ozone layer will be steadily restored. Since the Industrial Revolution about 200 years ago, fossil fuels like oil, coal and natural gas have been burnt to create energy, producing greenhouse gases well beyond the amount nature would normally produce.

Ozone Layer The ozone layer is found high up in the atmosphere, in a region called the stratosphere, between 19 and 30 kilometres (km) above the ground. Ozone here is made when energy from the Sun causes oxygen atoms to split apart. Most of the ozone in the stratosphere is formed over the equator, where the strength of the sunshine is greatest. It is then transported by winds towards the North and South Poles. Hence, the highest amounts of ozone in the ozone layer usually occur at high latitudes, over Northern Europe, Russia and Canada. In the 1970s, scientists discovered that CFCs could destroy ozone in the ozone layer. CFCs had been used in refrigeration, aerosols and fire extinguishers since the 1930s, so this posed a major problem.

See also: Zoology Ozone Holes Atmosphere Environmental Issues "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. Although the concentration of ozone in the ozone layer is very small, it is vitally important to life because it absorbs biologically harmful ultraviolet (UV) radiation from the Sun. The "thickness" of the ozone layer - that is, the total amount of ozone in a column overhead - varies by a large factor worldwide, being in general smaller near the equator and larger as one moves towards the poles. It also varies with season, being in general thicker during the spring and thinner during the autumn..

The Ozone Layer is an interactive hands-on exhibit showing how ozone in the stratosphere protects life on Earth - i.e. people, animals and plants - against dangerous UV radiation from the sun. About the exhibit The exhibit has the shape of a regular dodecahedron, a geometric structure with twelve planes. It is painted in unsaturated blue colours with wide cloud bands to resemble the Earth as seen from space. When the visitor approaches the exhibit, he stands at the border of the atmosphere and a window allows him to look down to the Earth through the atmosphere. When he puts his head near to the window a complete large globe is literally created due to the view box is made from a kaleidoscope with slightly tilted mirrors. On the other side of the exhibit, opposite to the view box, 3 large windows allows the visitor to look into the " Ozone factory " consisting of an Oxygen pressurised bottle, an Ozone generator, exhaust pump and filter. Also here a poster shows a graphical presentation of the action of Ozone in the Stratosphere to the radiation spectre from the Sun.

Heimlich Much attention is given by the media to an issue called ozone depletion and the impacts of this depletion on human health. But what is ozone and how is this depletion occurring? Ozone is a form of oxygen. The oxygen we breathe is composed of molecules of two atoms of oxygen (O ). Ozone is three atoms of oxygen bonded together. Ozone is found between six and 30 miles above the earth in the stratosphere and is more unstable and uncommon than the oxygen we breathe. Although ozone is found in only about one molecule out of every 100,000 air molecules, it provides a valuable protective screen for the earth. This fact sheet will explain how ozone interacts with ultraviolet rays and chlorine molecules, discuss causes and effects of ozone depletion and offer suggestions for citizen action. How Ozone Works Ozone, which is found in the stratosphere, filters the ultraviolet (UV) rays of the sun. The physical reaction is represented by O

@import "/css/main.css"; E-mail to a friend E-newsletter Contact us Overview ... Science The ozone layer Children often get the greenhouse effect and ozone depletion muddled. The two are not actually linked. Here is what is known about the causes and results of ozone depletion. What is the hole in the ozone layer? In 1984, it was found that the amount of ozone in the atmosphere above Antarctica was much less than expected. Since then, ozone 'holes' have been found over other parts of the world, including Europe. This general loss of ozone in the stratosphere, which is found 15 - 50km above the Earth's surface, is called ozone depletion and is not concentrated in 'holes'. Why does it matter? The ozone layer absorbs most of the ultraviolet light coming from the sun. This far ultraviolet light, called UV-B, is harmful to plants and animals. It causes cancers and eye damage in animals, and reduces the growth rate of some plants, including the microscopic plants called plankton living in the oceans, which are an important source of food for animals. How is it caused?
