Air Pollution Chemistry

Global atmosphere as a chemical system emphasizing physical factors and chemical processes that give rise to elevated surface ozone, particulate matter, and air toxics; international issues of air pollution transport and changing tropospheric background composition; and regulatory control strategies and challenges. Aimed at science and engineering majors. Recommended: either ATM S 358 or CHEM 162, MATH 126, and PHYS 123. Offered: jointly with CHEM 458; A.

Class description

This course examines the atmosphere as a chemical reactor. We review basic physical chemical concepts to describe the factors which govern the sources, transformations, and removal of species in the atmosphere. We then apply these concepts to a wide array of atmospheric phenomena: stratospheric ozone depletion, tropospheric pollution, cloud chemistry (acid rain), atmosphere-biosphere exchange, and composition-climate interactions. Prerequisite can be waived with permission of instructor.

Student learning goals

Identify the similarities and differences in the chemical processes occuring in the various regions of the atmosphere

Be able to apply fundamental physical and chemical concepts to describe why and when atmospheric composition changes.

Quantitatively assess the role of human activities on atmospheric composition.

Analyze atmospheric observations to derive an understanding of the underlying chemical and physical mechanisms.

Describe the important couplings between the atmosphere and other Earth subsystems and their implications for feedbacks.

General method of instruction

A combination of lectures, group problem solving, and literature discussions are used.

Recommended preparation

Some general chemistry is helpful, but perhaps most useful is a strong foundation in algebra, simple calculus and first-year university physics.

Class assignments and grading

Problem sets will be solved in class in a group setting. There will be 4 in-class, graded exams. There is also a final project where students chose a problem to research in greater detail and submit a 10-15 pg paper at the end of the quarter.

Grades are assigned based on in-class exams, the quality of the problem sets, the final project, and to a small degree on participation and the discussion of assigned readings.


The information above is intended to be helpful in choosing courses. Because the instructor may further develop his/her plans for this course, its characteristics are subject to change without notice. In most cases, the official course syllabus will be distributed on the first day of class.
