The Atmospheric Ozone Layer

A complete report regariding the source, causes and impact of the atmospheric ozone floor on the environment A complete and clearly compose repoty. comminuted effort. The stratospheric ozone layer exists at altitudes between about 10 and 40km depending on latitude, just above the tropopause. Its existence is crucial for liveliness on earth as we know it, because the ozone layer controls the absorption of a portion of the deadly ultraviolet (UV) rays from the sun. UV-A rays, including wavelengths between 320 and 400nm, are non unnatural by ozone. UV-C rays between 200 and 280nm, are jai lead by the other atmospheric constituents besides ozone. It is the UV-B rays, between 280 and 320nm, oblivious unaccompanied by ozone, that are of the greatest concern. Any press dethaw or destruction of the stratospheric ozone layer could mean greater liveliness and soul of UV-B radiation would reach the earth, creating among other problems, an increase in peel cancer (melanoma) in hum ans. As UV-B rays increase, the hatchway of interferences with the chemical formula life cycles of animals and plants would become more of a reality, with the eventual possibility of death. Stratospheric ozone has been use for several decades as a tracer for stratospheric circulation. initial appraisements were make by ozonesondes attached to high altitude balloons, by chemical-sondes or optical devices, which measured ozone concentrations through the depletion of UV light. However, the learn to measure ozone concentrations from the surface at regular intervals, led to the maturement of the dobson fly spectrophotometer in the 1960s. The British Antarctic batch has the responsibility to routinely monitor stratospheric ozone levels over the Antarctic send at Halley alcove (76°S 27°W) and at Argentinian Islands (65°S 64°W). Analysis of ozone measurements in 1984 by a team led by John Farnam, made the floor discovery that bounds values of total ozone during the...
