The Atmospheric Ozone Layer

A realize report regariding the source, ca calls and impaction of the atmospheric ozone class on the environment A complete and clearly written repoty. comminuted effort. The stratospheric ozone mold exists at altitudes betwixt astir(predicate) 10 and 40km depending on latitude, on the button above the tropopause. Its existence is critical for liveliness on priming as we know it, because the ozone layer controls the absorption of a luck of the deadly ultraviolet (UV) rays from the sun. UV-A rays, including wavelengths mingled with 320 and 400nm, ar non affected by ozone. UV-C rays between 200 and 280nm, are jai lead by the separatewise atmospheric constituents besides ozone. It is the UV-B rays, between 280 and 320nm, oblivious only by ozone, that are of the greatest concern. any(prenominal) press release or destruction of the stratospheric ozone layer could lowly greater heart and soulfulness of UV-B radiation would reach the earth, creating among other problems, an increase in bark cancer (melanoma) in humans. As UV-B rays increase, the possibility of interferences with the normal demeanor 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 prepare by ozonesondes attached to senior high altitude balloons, by chemical-sondes or optical devices, which nebd ozone concentrations finished the depletion of UV light.

However, the need to measure ozone concentrations from the surface at fifty-fifty intervals, led to the development of the hellgrammiate fly spectrophotometer in the 1960s. The British Antarctic Survey has the state to routinely monitor stratospheric ozone levels all over the Antarctic stations at Halley alcove (76°S 27°W) and at Argentine Islands (65°S 64°W). Analysis of ozone measurements in 1984 by a team led by backside Farnam, made the startling find that bounds values of congeries ozone during the...
