Atmospheric ozone variability in the context of global change

A survey has been made of the role and place of atmospheric ozone dynamics in both the stratosphere and troposphere in the context of global change. Impacts on the ozone layer from solar activity (extraterrestrial solar ultraviolet irradiance variations), volcanic eruptions and high-flying aircraft have been discussed. Tropospheric ozone and surface ultraviolet irradiance changes have been considered, including relevant biological implications. Influences of the stratospheric ozone depletion on climate change have been discussed with emphasis on a coupled nature of ozone-climate interrelations. A necessity has been substantiated to develop a complex ozone studies programme in the context of the World Climate Research Programme and the International Geosphere-Biosphere Programme.
