Climate change and its consequences are one of the most important issues humanity will have to face in the coming decades. Reliable modeling can only come from an accurate knowledge of the composition of the atmosphere. This program is aimed at the development of a powerful in-situ instrument to detect pollutants in the atmosphere using a variant of tunable diode laser absorption spectroscopy. The miniature dimension of the instrument will allow an easy deployment on small balloon payloads or aircrafts for atmospheric measurement campaigns. Additionally, this new instrument will find many applications in industry (e.g., leak detection, process control systems, etc), in agriculture (e.g., emission from soils, livestock, etc) and in forensic science (e.g., detection of explosives, narcotics and other chemical substances, etc).
