GOME Observations of Stratospheric Trace Gas Distributions during the Splitting Vortex Event in the Antarctic Winter of 2002. Part I: Measurements

摘要: Abstract Measurements from the Global Ozone Monitoring Experiment (GOME) are used to study chemical evolution of stratosphere during unusual 2002 winter in Southern Hemisphere. The results show that chlorine activation as indicated by OClO columns was similar previous years vortex until major warming on 26 September after which it decreased rapidly. Similarly, NO2 were only slightly larger than before warming, indicating strong denoxification and probably also denitrification. After very large observed for a few days, then again reestablished itself final warming. much any year onward, mainly result dynamical situation. Analysis global long-term time series GOME measurements since 1996 provides unique opportunity set austral into perspective. data reveal th...
