- List important measurable trace components of air.
- Explain why it is important to monitor the key trace gases present in the air.
- Define the different units used to describe the amount of trace gases in the atmosphere, including dry air mole fraction, mixing ratio, number density, and partial pressure.
- Characterize the primary types of measurements used to measure different trace gas components in the air (including optical and molecular spectrometry, chromatographic, and chemical conversion methods).
- Identify key instruments that are associated with each measurement technique.
- Describe common issues in the measurement of trace gases, including inlet losses, sample contamination, transformations prior to analysis, and sensor drift.
- Categorize the factors required to be sure that a particular instrument will have adequate uncertainty specifications and will provide measurements representative of the atmospheric phenomenon to be studied.
- Explain the types of calibration methods used to quantify gas composition of the atmosphere.
