K aren Ozone seam The ozone mould is a layer in Earths melody which contains comparatively full(prenominal) concentrations of ozone (O3). This layer absorbs 9799% of the Suns high oftenness ultraviolet light, which is damaging to life on Earth.[1] It is in general laid in the lower portion of the stratosphere from approximately 13 to 40 kilometres (8.1 to 25 mi) above Earth, though the thickness varies seasonally and geographically.[2] The ozone layer was disc everyplaceed in 1913 by the French physicists Charles Fabry and Henri Buisson. Its properties were explored in token by the British meteorologist G. M. B. hellgrammiate, who developed a unprejudiced spectrophotometer (the Dobsonmeter) that could be used to measure stratospheric ozone from the ground. Between 1928 and 1958 Dobson ceremonious a worldwide network of ozone monitoring stations, which continue to snuff it to this day. The Dobson unit, a convenient measure of the columned immersion of ozone belt, is n amed in his honor. Distribution of ozone in the stratosphere The thickness of the ozone layerthat is, the check amount of ozone in a column overheadvaries by a large factor worldwide, world in usual smaller near the equator and larger towards the poles. It also varies with season, being in general thicker during the spring and thinner during the autumn in the Union hemisphere. The reasons for this latitude and seasonal dependence are complicated, involving atmospheric circulation patterns as well as solar intensity. Since stratospheric ozone is produced by solar UV radiation, one might expect to find the highest ozone levels over the tropical zone and the lowest over polar regions. The homogeneous argument would crest one to expect the highest ozone levels in the pass and the lowest in the winter. The observed behavior is very varied: most of the ozone is set in the mid-to-high latitudes of the northern and southern hemispheres, and the highest levels are found in the spring, not summer, and the lowest in the au! tumn, not...If you command to get a full essay, order it on our website: OrderCustomPaper.com
