Short summary

Surface ozone, the most abundant atmospheric oxidant, has been measured since 2004 at the coastal East Antarctic site of Dumont d’Urville, and since 2007 at the Concordia station located on the high East Antarctic plateau. Long-term changes, seasonal and diurnal cycles, as well as inter-annual summer variability observed at these two East Antarctic sites are discussed. Influences like sea ice extent and outflow from inland Antarctica are discussed.
