SYLLABUS
METO 634: Air Sampling and
Analysis
Spring 2006
SUMMARY: Theory and application of analytical techniques for the analysis of meteorological variables, and atmospheric gases and particles including priority pollutants. Hands on experience with traditional and state-of-the-art instruments will be provided. Discussion of the combined chemical and meteorological considerations in designing field experiments. One hour of lecture and four hours of laboratory per week. Prerequisites: METO 434, or METO 637, or consent of the instructor.
