SYLLABUS

METO 634 Air Sampling and Analysis

Fall 1998

SUMMARY: Theory and application of analytical techniques for the analysis of 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 to five hours of laboratory per week. Prerequisites: METO 434, or METO 637, or consent of the instructor.
