1 I/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 I/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, 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

5 I/5 student presentations about WMO ozone assessment 2006 Summary of selected chapters/sections from WMO Scientific Assessment of Ozone Depletion minute presentations at the end of the semester

6 I/6 WMO ozone assessment and Montreal Protocol

7 I/7 WMO ozone assessment and Montreal Protocol

8 I/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?) Preface WMO O3 Assessment 2006:
