EAS 6430 / CEE 8823: EXPERIMENTAL METHODS IN AIR QUALITY

Instructors: Rodney Weber and Prof. Jennifer Kaiser

Description: Introduction to experimental and field methods with a focus on measurements of atmospheric gases and particulates associated with poor air quality.

Educational Objectives: Upon completion of this course, the student should have knowledge of the theory behind commonly used and research-grade atmospheric instrumentation. as well as practical lab/field skills and data analysis.

Grades: 6 Lab experiments all of equal grade (i.e., 100/6 = 16.7%).

Lecture: There will be 1 lecture per week.

Labs:  Lab experiments will take place mainly in the ES&T penthouse lab.  Sign up for labs will be arranged by TA.  Lab reports due dates are shown below.  Ideally 2 students per lab group, where each student is expected to submit their own lab report. Note, below is a typical lab schedule, but changes may be made depending on availability of instruments during a particular semester.

CEE / EAS 6790: AIR POLLUTION PHYSICS AND CHEMISTRY

Instructors: Rodney Weber, A.G. (Ted) Russell

Objective.  This course is a graduate level introduction to air pollutants, and in particular their atmospheric dynamics and impacts.  The student, upon completion of this course should have a knowledge of which air pollutants are of concern, their source, fate, atmospheric transport and transformation and policies developed to help manage the problem.  Topics include: air pollutants of interest, air pollution impacts, sources of air pollutants, atmospheric transport (including dispersion and deposition), atmospheric chemistry, aerosol dynamics, control strategy development and air pollution management.

Textbooks: Atmospheric Chemistry and Physics: from Air Pollution to Climate Change, J.H. Seinfeld and S. Pandis (S&P), Wiley Interscience, (most recent edition) D.J. Jacob (PU Press) Introduction to Atmospheric Chemistry.

(note the order of topics can change year-to-year)
