Daily broad-band measurements of solar ultraviolet radiation reaching the ground at Athens, Greece (38¿N, 24¿E) during 1989--1991 in conjunction with daily total ozone measurements deduced from satellite and ground-based instrumentation were used to investigate their association. Furthermore, employing a parametric model, the spectral and broad-band solar ultraviolet radiation for the period 1979--1991 were calculated considering the total ozone values, derived from the satellite Nimbus-7.

Total ozone reductions of 2.5% during summertime and 7% during wintertime per decade, cause an increase in erythemally active UV-B irradiance of 5% and 14% respectively. ¿ American Geophysical Union 1994
