摘要: The ozone hole over Antarctica reflects the as yet largest observed perturbation of stratospheric layer. During this event layer in an altitude range 14–22 km is significantly depleted with local losses up to 90% and changes total column 60%. antarctic appears annually during months September/October. Although it was first discovered 1985, its appearance dates back mid-1970s. Since time, has grown both depth size. In October 1991 amounts were low 110 DU; area covered approximately 7% southern hemisphere.
