ATMS 558 Atmospheric Chemistry:
Class Meeting Times and Location: Tuesdays and Thursdays 9:00-10:20 am in Room 310 in the Atmospheric Sciences Building.
Course Description: Graduate course providing an introduction to the physical and chemical processes determining the composition of the atmosphere and its implications for climate, ecosystems, and human welfare. We will look at the role of atmospheric chemistry behind several important global environmental problems: Stratospheric ozone depletion, tropospheric ozone and photochemical smog, oxidizing capacity of the atmosphere, acid rain, mercury biogeochemical cycling, global warming.
Instructor: Lyatt Jaeglé (email@example.com; 685-2679; Office: ATG 302)
Office hours: After class or e-mail me to set up a time.
Prerequisites: ATM S 501 or permission of instructor.
Grading policy: Homework, 60%; Project paper and presentation, 30%; Class participation, 10%.
- Introduction to Atmospheric Chemistry, by D.J. Jacob, Princeton University Press, 1999. The lectures will largely follow this textbook. Each week the students will be required to read material of direct relevance to the class. Textbook + Errata available online: http://acmg.seas.harvard.edu/people/faculty/djj/book/index.html
- Atmospheric Chemistry and Physics: from Air pollution to Climate change, by J.H. Seinfeld and S.N. Pandis, Wiley, 2016 (3rd edition). This book is available online via the UW libraries: https://uwashington.on.worldcat.org/oclc/929985467
1) Introduction and Fundamentals. Photochemistry; Theory of gas-phase reaction rates; Multiphase chemistry; Analysis of reaction mechanisms; Timescales; Box models.
2) Stratospheric chemistry. Stratospheric ozone and the Chapman mechanism; Catalytic loss cycles (HOx, NOy and halogen chemistry); Polar and mid-latitude ozone depletion; Role of aerosol chemistry in the stratosphere.
3) Tropospheric Chemistry. Oxidizing capacity of the atmosphere; Tropospheric ozone; Tropospheric NOx and hydrocarbons; Air pollution and ozone smog; Tropospheric Sulfur and tropospheric aerosols.
4) Atmospheric Chemistry and Climate. Global warming and atmospheric chemistry: direct and indirect effects. Chemistry-climate feedbacks.

Students will write a paper and give a 10-minute presentation during the last week of class. A list of possible topics is included below, or students can pick a topic of their own choosing. The paper should be at least 5 pages long (but no more than 10 pages) using ~1.5 line spacing and include at least 10 references in the peer-reviewed literature, as well as figures to illustrate your points. To find relevant papers, a search on the Web of Science is an excellent starting point.
