Where is found the ozone layer

Once inside an instrument, ozone can be measured by its absorption of ultraviolet UV light or by the electrical current produced in an ozone chemical reaction.

Ben Davis July 31, Where is the highest concentration of ozone? What two places is the ozone found? Which layer is rich in ozone? Is there ozone in the atmosphere? Why is ozone bad for you? How is ozone formed in higher level of atmosphere? How is ozone formed in the higher level of atmosphere damage to ozone layer is a cause of concern? How is ozone formed? How is the ozone layer doing ? Why is ozone layer important for us? What are the causes and effects of ozone layer?

What are the causes of ozone layer? What is ozone layer depletion and its effects? Ozone is destroyed when it reacts with molecules containing nitrogen, hydrogen, chlorine, or bromine.

Some of the molecules that destroy ozone occur naturally, but people have created others. The total mass of ozone in the atmosphere is about 3 billion metric tons. That may seem like a lot, but it is only 0. The peak concentration of ozone occurs at an altitude of roughly 32 kilometers 20 miles above the surface of the Earth. At that altitude, ozone concentration can be as high as 15 parts per million 0. The concentration of ozone varies with altitude. Peak concentrations, an average of 8 molecules of ozone per million molecules in the atmosphere, occur between an altitude of 30 and 35 kilometers.

Ozone in the stratosphere absorbs most of the ultraviolet radiation from the Sun. Ozone screens all of the most energetic, UV-c, radiation, and most of the UV-b radiation. Ozone only screens about half of the UV-a radiation. It is calculated from the area on the Earth that is enclosed by a line with a constant value of Dobson Units. The value of Dobson Units is chosen since total ozone values of less than Dobson Units were not found in the historic observations over Antarctica prior to Also, from direct measurements over Antarctica, a column ozone level of less than Dobson Units is a result of the ozone loss from chlorine and bromine compounds.

The graphs above show the progress of the ozone hole for The gray shading indicates the highest and lowest values measured since The red numbers are the maximum or minimum values.

The stratospheric temperature and the amount of sunlight reaching the south polar region control the depth and size of the Antarctic ozone hole. The data for the ozone hole area , the minimum ozone , and the minimum stratospheric temperature are available.

Also available is a table of values showing the maximum ozone hole area and the minimum ozone values for each year. Click on the image to get a table of values. The graphs above show the variations of ozone from year to year. The red bars indicate the largest area and the lowest minimum value.
