# Advanced Course in Atmospheric Physics and Chemistry 2 Credits
Instructors: F. Hasebe, J. Hirokawa
Key Words: stratosphere, troposphere, ozone layer, meridional circulation, general circulation, potential vorticity, polar vortex, ozone hole, transport process, radiative process, photochemical process, free radicals, catalytic ozone destruction, polar stratospheric cloud, heterogeneous reaction, air quality, air pollution
Course Objectives: Stratospheric environment is controlled by the interactions between atmospheric dynamics, chemistry and radiation. Tropospheric environment is changing due to the regional air pollution. This lecture will cover the dynamical and chemical processes of atmospheric trace gases that play an important role in the stratosphere and the troposphere. The subject to be discussed includes the stratospheric transport processes, the formation of the ozone layer, anthropogenic ozone depletion, the mechanism of the ozone hole, and the production of photochemical oxidants
Course Goals: To understand the basic concepts on the atmospheric dynamics, chemistry, and radiation that drive the variabilities in stratospheric ozone and tropospheric air quality.
Course Schedule:

1. Introduction	8. Chemical reactions in the atmosphere 1 (photodissociation)
2. Dynamical processes in the atmosphere 1 (atmospheric motion)	9. Chemical reactions in the atmosphere 2 (bimolecular and three-body reactions)
3. Dynamical processes in the atmosphere 2 (vorticity and waves)	10. Chemistry in the stratosphere 1 (Chapman mechanism)
4. Dynamical processes in the atmosphere 3 (Rossby waves)	11. Chemistry in the stratosphere 2 (chlorine and bromine chemistry)
5. Dynamical processes in the atmosphere 4 (mean meridional circulation)	12. Chemistry in the stratosphere 3 (chemistry of the ozone hole)
6. Dynamics in the stratosphere (general circulation)	13. Chemistry in the troposphere 1 (chemistry of the photochemical oxidants)
7. Dynamics in the troposphere (atmospheric boundary layer)	14. Chemistry in the troposphere 2 (chemistry of atmospheric aerosols)	home
