In the study of global warming, obtaining good data demands widely deployed, accurate, and reliable sensors for identifying and understanding the origins, sources, and fates of greenhouse gases. Sensing technologies based on tunable diode laser absorption spectroscopy are starting to provide some of this critical data.
