As scientists attempt to assess the threat of global warming, accurate monitoring of Earth’s atmosphere becomes increasingly important. Even some pollutants that have minimal short-term impact on the climate, such as carbon monoxide, may control other major greenhouse gases, such as ozone. When Charles Chackerian examines compounds like carbon monoxide in the lab, he stresses the research’s “importance in evaluating the ‘health’ of the Earth’s atmosphere.” By conducting spectroscopic studies of critical compounds under well-controlled conditions, Chackerian provides a foundation for studying the same compounds high in the Earth’s atmosphere—and perhaps some day, in the atmospheres of planets circling other stars.
