An estimation of the surface solar ultraviolet irradiance during an extreme total ozone minimum

A simple theoretical algorithm has been employed to estimate the solar ultr aviolet irradiance at Athens, Greece (38.7 degrees N, 23.4 degrees E) durin g, summertime 1993, a year of extreme total ozone minimum in the existing d ata record. This estimation has been performed by using total ozone measure ments as derived by both ground-based and satellite instrumentation. The ut ilization of the present investigation will assist to the various assesment s for the risk of human health from the biologically-effective doses of the solar ultraviolet radiation arrived at the earth's surface during that tim e period.
