Taschenbuch. Etat : Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - High Quality Content by WIKIPEDIA articles! The ozone layer is a layer in Earth's atmosphere which contains relatively high concentrations of ozone (O3). This layer absorbs 93-99% of the sun's high frequency ultraviolet light, which is potentially damaging to life on earth. Over 91% of the ozone in Earth's atmosphere is present here. It is mainly located in the lower portion of the stratosphere from approximately 10 km to 50 km above Earth, 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 (the Dobsonmeter) 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 columnar density of ozone overhead, is named in his honor.…

Taschenbuch. Etat : Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Please note that the content of this book primarily consists of articlesavailable from Wikipedia or other free sources online.The Dobson unit(DU) is a unit of measurement of atmospheric ozone columnar densityspecifically ozone in the stratospheric ozone layer. One Dobson unitrefers to a layer of ozone that would be 10µm thick under standardtemperature and pressure.For example, 300DU of ozone brought down tothe surface of the Earth at 0°C would occupy a layer only 3mm thick.One DU is 2.69×1016 ozone molecules per square centimetre, or 2.69×1020per square metre. This is 0.4462 millimoles of ozone per square metre.…
