Variations of UV irradiance at Antarctic station Concordia during the springs of 2008 and 2009
Abstract The features of solar UV irradiance measured at the Italian-French Antarctic Plateau station, Concordia, during the springs of 2008 and 2009 are presented and discussed. In order to study the impact of the large springtime variations in total ozone column on the fraction of ultraviolet B (U...
