摘要

In this study the variations in the surface ozone concentration, the solarultraviolet radiation and the meteorological parameters at the groundbefore, during and after the total solar eclipse of 29 March 2006 have beenexamined. This analysis is based on the measurements performed at fourstations located in the greater Athens basin in Greece. The experimentaldata demonstrated that the solar eclipse phenomenon affects the surfaceozone concentration as well as the temperature, the relative humidity andthe wind speed near the ground. The decrease in the surface ozoneconcentration that observed after the beginning of the eclipse event lastedalmost two hours, probably due to the decreased efficiency of thephotochemical ozone formation. The reduction of the solar ultravioletradiation at 312 and 365 nm reached 97% and 93% respectively, whilethe air temperature dropped, the relative humidity increased and the windspeed decreased.
