Review Articles

A review has been made recently studying global total ozone changes (including stratospheric and tropospheric components), as well as biologically active surface solar ultraviolet (UV-B) radiation variations on the basis of satellite and conventional surface observations (Kondratyev and Varotsos, Part I). In the aforementioned review, relevant impact on terrestrial and aquatic ecosystems, as well as on biochemical cycles and man, have been discussed. Special attention has bee paid to the analysis of observed and potential impacts of enhanced UV-B radiation on biogeochemical cycles and the chemical composition of the atmosphere. In this context, possibilities remote sensing techniques applications aimed at obtaining more complete information on atmospheric concentrations of various trace gases determining the ozone content have been considered in the present paper.
