Measurements of the solar ultraviolet radiation have been made in Argolida (location not influenced by air pollution), South–East Greece (37.5°N, 24°E), since July of 1993. The data presented here show the daily and monthly variability within the ultraviolet–B wave band and its relation to the total ozone amount during the summer – fall period, mainly characterized by the lowest total ozone values ever observed in Southern Europe since 1978.
