Earth's ozone shield and its changes
Abstract
The current state of the ozone layer problem is presented in a systematic manner. The 'ozone hole' phenomenon observed in the Antarctic in spring and substantial decreases in the springtime ozone content observed during the period 1983-87 at middle latitudes in the Northern Hemisphere and in the Arctic are described. Possible explanations for these phenomena are proposed which are based on the main factors determining the formation of the earth's ozonosphere; possible effects of changes in the ozone layer on the humans and the biosphere are discussed. Methods for measuring changes in the contents of ozone and ozone-active impurities in different parts of the atmosphere are presented, as are measurement results. Future changes in ozone content are estimated for different scenarios of the effect of anthropogenic factors on the atmosphere.
