Short summary

Ozone measurements onboard three Concordiasi balloons flown in the stratosphere in the Antarctic spring of 2010 are presented. These measurements are the first long-duration in situ measurements of Antarctic springtime stratospheric ozone. By matching air parcels, ozone loss rates where derived. Downwind of the Antarctic Peninsula, very large ozone losses of up to 230 ppb per day or 16 ppbv per sunlit hour were observed. These high rates are consistent with almost complete chlorine activation.
