The Atmospheric Ozone Layer

A breeze through and through report regariding the source, ca ingestions and concern of the atmospheric ozone spirit level on the environment A complete and clearly written repoty. comminuted effort. The stratospheric ozone floor exists at altitudes amidst some 10 and 40km depending on latitude, clean above the tropopause. Its existence is all-important(a) for liveliness on body politic as we know it, because the ozone layer controls the absorption of a per centum of the deadly ultraviolet (UV) rays from the sun. UV-A rays, including wavelengths between 320 and 400nm, argon non affected by ozone. UV-C rays between 200 and 280nm, are jai lead by the former(a) 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 remember greater heart and soul of UV-B radiation would reach the earth, creating among early(a) problems, an increase in whittle cancer (melanoma) in humans. As UV-B rays increase, the possibility of interferences with the normal animation 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 take away by ozonesondes attached to spicy altitude balloons, by chemical-sondes or optical devices, which rhythmd ozone concentrations through the depletion of UV light.

However, the need to measure ozone concentrations from the surface at fixity intervals, led to the development of the dobsonfly fly spectrophotometer in the 1960s. The British Antarctic Survey has the state to routinely monitor stratospheric ozone levels 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 group led by potty Farnam, made the startling breakthrough that bounds values of complete ozone during the...
