C. Varotsos et al., ON THE RELATIONSHIP BETWEEN TOTAL OZONE AND SOLAR ULTRAVIOLET-RADIATION AT ST-PETERSBURG, RUSSIA, Geophysical research letters, 22(24), 1995, pp. 3481-3484
Daily total ozone observations made with the Total Ozone Mapping Spect
rometer (TOMS) flown on the satellite Nimbus-7 during 1978-1992, have
been used in order to investigate the increase in the daily broad-band
and spectral solar ultraviolet radiation reaching the ground through
a recently developed parametric model. Total ozone reductions of 3.0%
during summer time and 11% during winter time per decade, at St. Peter
sburg (60 degrees N, 30 degrees E), Russia, cause an increase in eryth
ematically active ultraviolet irradiance of at least 7% and 22%, respe
ctively.
