  1. Overview: Atmospheric transport and ozone chemistry SS2008 • Learning more about variability of atmospheric ozone related to transport and chemistry • How is chemistry and transport changing in a future climate?

  2. Atmospheric transport and ozone chemistry SS2008 Special topics Thursday, 14:15h (sharp)-15:45h, Room NW1/S3032 Lecturer: Mark Weber Contact: Room NW1/S4350, Tel. –2362, weber@uni-bremen.de Topics • atmospheric dynamics (circulation and transport) • radiative transfer, heating, and vertical transport • middle atmospheric chemistry • ozone chemistry and catalytic cycles • heterogeneous chemistry and the ozone hole • the tropical tropopause • solar (decadal) variability and dynamical coupling • greenhouse gasses and climate-chemistry interaction

  8. Important issues in the assessment ozone recovery expected from leveling off of stratospheric chlorine (Montreal Protocol and ammendments), but role of stratospheric bromine/shortlived substances may become more important How does climate change affect the ozone layer (Antarctic ozone hole anomaly in 2002? changes in atmpospheric transport and chemistry?)
