| Summary: | Chemically-induced total ozone column loss derived by comparing observations of total ozone with a chemical transport model calculation where ozone is treated as a chemically inert tracer. The observations are carried out with SAOZ UV-Visible spectrometers at high-latitude sites of the GAW-contributing Network for the Detection of Atmospheric Composition Change (NDACC). Although the 2005-06 Arctic stratospheric winter overall featured a weak vortex and was one of the mildest on record, low temperatures in December and January, combined with a displacement of the vortex towards sunlit latitudes resulted in significant ozone loss, although to a lesser extent than seen during cold Arctic winters. The plot is provided by Florence Goutail, Service d'A'éronomie, CNRS. |
