Daily total ozone observations made during 1985-1993 by both the Total Ozone Mapping Spectrometer (TOMS) flown on the Satellite Nimbus-7 and the Dobson Spectrophotemeter have been used in order to investigate the fluctuation of the daily broad-band and spectral solar ultraviolet radiation reaching the ground. This investigation has been performed by employing a recently developed parametric algorithm for the estimation of the spectral and broad-band solar ultraviolet radiation which takes the total ozone variations into consideration. Total ozone reduction during the summertime from 1985 to 1993 over Athens, Greece (37.6° N, 23,4° E), cause an increase in the ultraviolet irradiance which reaches the ground of 0.54%, 0.98%, 2.60% and 0.79% per decade for the months of July at 300 nm, 312 nm, 320 nm and UVB (280-320 nm), respectively.
