The earth's ozone layer ozone layerthe region of the stratosphere containing the bulk of atmospheric ozone the ozone layer lies approximately 15-40 kilometers (10-25 miles) above the earth's surface, in the stratosphere. The standard way to express total ozone levels (the amount of ozone in a given vertical column) in the atmosphere is by using dobson units point measurements are reported as mole fractions in nmol/mol (parts per billion, ppb) or as concentrations in μg/m 3. Ozone has hundreds of industrial uses, as well as being used as a disinfectant, but far and away the greatest effect o3 has on our lives is the ozone layer, a portion of the upper stratosphere where ozone tends to collect, which absorbs a large portion of the sun’s deadly uv output. Ozone is mainly found in two regions of the earth's atmosphere most ozone (about 90%) resides in a layer that begins between 6 and 10 miles (10 and 17 kilometers) above the earth's surface and extends up to about 30 miles (50 kilometers. The highest levels of ozone in the atmosphere are in the stratosphere, in a region also known as the ozone layer between about 10 km and 50 km above the surface (or between about 6 and 31 miles) however, even in this layer, the ozone concentrations are only two to eight parts per million, so most of the oxygen there is dioxygen, o 2 , at about 210,000 parts per million by volume.
However, the atmospheric levels of nearly all these substances have declined substantially in the past two decades additional information nasa provides daily images, data, and information from satellite instruments that monitor the ozone layer and the ozone hole, a thinning break in the stratospheric ozone layer. Ozone layer, also called ozonosphere, region of the upper atmosphere, between roughly 15 and 35 km (9 and 22 miles) above earth’s surface, containing relatively high concentrations of ozone molecules (o 3. Variations in temperature and pressure divide the earths atmosphere into layers, shown below, and mixing of gases between the layers happens very slowly the ozone layer absorbs 97-99% of the sun's high frequency ultraviolet light, light which is potentially damaging to life on earth every 1.
In addition, atmospheric measurements show that the depletion of the ozone layer increased the amount of uv radiation reaching earth’s surface ozonesonde researchers launching a balloon carrying an ozonesonde, an instrument that measures ozone in the atmosphere, at amundsen-scott south pole station in antarctica. Ozone layer protection the stratospheric ozone layer is earth’s “sunscreen” – protecting living things from too much ultraviolet radiation the emission of ozone depleting substances has been damaging the ozone layer.
The ozone layer absorbs 97-99% of the sun's high frequency ultraviolet light, light which is potentially damaging to life on earth every 1% decrease in the earths ozone shield is projected to increases the amount of uv light exposure to the lower atmosphere by 2.
Earth's atmospheric layers diagram of the layers within earth's atmosphere the ozone layer, which absorbs and scatters the solar ultraviolet radiation, is in this layer mesosphere the mesosphere starts just above the stratosphere and extends to 85 kilometers (53 miles) high meteors burn up in this layer. Ozone depletion: ozone depletion, gradual thinning of earth’s ozone layer caused by the release of chemical compounds containing gaseous chlorine or bromine from industry and other human activities the thinning is most pronounced in the polar regions, especially over antarctica. When the ozone in this layer absorbs uv light from the sun, it increases in temperature in the mesosphere , ozone concentration decreases this means there is less absorption of uv light in this layer of atmosphere.
The ozone in this region is commonly known as the ozone layer the remaining ozone is in the lower region of the atmosphere, which is commonly called the troposphere the figure (above) shows an example of how ozone is distributed in the atmosphere. The ozone layer the ozone layer is a layer in earth's atmosphere which contains relatively high concentrations of ozone (o3) this layer absorbs 97-99% of the sun's high frequency ultraviolet light, which is potentially damaging to life on earth.
The stratospheric ozone layer absorbs ultraviolet light (uv) emitted by the sun if the solar uv light were able to penetrate the stratosphere and troposphere and reach the earth’s surface, it would seriously damage our ecosystem for example, ult.
