| Abstract: | 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 Spectrophotometer have been used in order to investigate the fluctuations 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 reductions 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. |
