Special issue}, month = {Jul}, note = {P(論文), Man-made CFCs have been banned largely because of fears that increasing amounts of these chemicals in the atmosphere would lead to elevated levels of ultraviolet flux on the earth with resulting adverse biological effects. The link between ozone depletion and elevated levels of UV is clearly demonstrated with data from the National Science Foundation's UV Monitoring Network for Polar Regions. This network of six sites (recently expanded with a seventh, affiliated site), ranging from the South Pole to Barrow, Alaska, has routinely made high spectral resolution measurements of UV irradiance since 1988. These data allow researchers to conduct field experiments on organisms, evaluate laboratory experiments, test models, and predict the impact of ozone depletion on the environment. The network of instruments is described, and data from the 1996 "Ozone Hole, " showing the impact of ozone depletion on incident spectral irradiance, is presented along with estimates of its biological impact.}, pages = {111--121}, title = {Polar UV measurements-Ozone depletion and biological significance}, volume = {52}, year = {1998} }
