7. Scope of the course in credits

5 cr

8. Teacher coordinating the course

Prof. Alexey Karpechko (Finnish Meteorological Institute)

9. Course learning outcomes

After the course, the students will understand basics of stratospheric chemistry and dynamics as well as the role of the stratosphere in Earth's climate system.

10. Course completion methods

The course will consist of lectures, exercises, and a final examination. 70% lecture attendance is required.

11. Prerequisites

Basic knowledge of atmospheric dynamics, physics, and general circulation is assumed. However, the course may be useful also with a more general physical sciences background, for instance, for aerosol physics graduate and doctoral students.

12. Recommended optional studies

ATM306 Basics of atmospheric chemistry

ATM357 Atmospheric Radiation

13. Course content

The course familiarizes the students with the chemistry and dynamics of the stratosphere. The topics covered are as follows:

  • Important chemical reaction chains in the stratosphere
  • Radiative transfer and radiative heating in the stratosphere
  • Theory of stratospheric ozone depletion
  • Linear theory of planetary wave propagation
  • General circulation of the stratosphere
  • Interaction between waves and the mean flow
  • Transport in the stratosphere
  • Ozone and UV radiation

14. Recommended and required literature

The lectures are based on the material from the following books, as well as from selected scientific articles:

  • Andrews, D G, J R Holton and C B Leovy (1987) Middle Atmosphere Dynamics. Academic Press, 489 pp.
  • Brasseur, G and S Solomon (2005) Aeronomy of the Middle Atmosphere: Chemistry and Physics of the Stratosphere and Mesosphere. Springer, Dordrecht, The Netherlands, 3rd edition (revised and enlarged).
  • Holton, J  (2004) An Introduction to Dynamic Meteorology. Academic Press, pp. 535.

15. Activities and teaching methods in support of learning

There are weekly lectures and exercises.

16. Assessment practices and criteria, grading scale

The grading is based on the exercises (30%) and the final exam (70%).
