Abstract
Measurements of column ozone were carried out at Athens, Greece, using a Dobson spectrophotometer during the solar eclipse of 11 August 1999. Taking into account the performance of the Dobson spectrophotometer during an eclipse event, the observation analysis showed positive and negative fluctuations of the column ozone of ca 2% within a period of two hours, approximately. Furthermore, observations of the surface ozone concentration and solar ultraviolet radiation reaching the ground during the eclipse event are presented.
