Ozone total columns are regularly measured from the ground by SAOZ uv-visible spectrometers. Making use of a 3D transport model to remove the dynamical component in the ozone variations, total column chemical loss have been derived each winter since 1993. According to this evaluation, the total ozone reduction in 2000 started during the second week of January and extended until mid-March, reaching 22% at the end of the winter. Although significant, the cumulative loss during the winter of 2000 was smaller than the 30-32% of 1995 and 1996. This result is consistent with balloon (SAOZ) and satellite (POAM III) profile data indicating that the most important loss of 50-60% occurred around 17 km, but was also but restricted to a limited altitude range. This is in constrast to the record years of 1995 and 1996 when the ozone loss extended over a larger altitude range. In addition to ozone, NO2 and OClO have been also measured by the balloon-borne SAOZ. The time and altitude evolution of NO2, indicative of denoxification and denitrification, and OClO, indicative of chlorine activation, are found highly anti-correlated. Chlorine activation occurred only during periods and at altitudes (14-20 km) where the NO2 concentration dropped after denoxification on PSCs.
