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).

气候变化及其后果是人类在未来几十年必须面对的最重要问题之一。可靠的建模只能来自对大气成分的准确了解。该计划旨在开发一种功能强大的现场仪器，使用可调谐二极管激光吸收光谱法的变体来检测大气中的污染物。该仪器的微型尺寸将允许在小型气球有效载荷或飞机上轻松部署，用于大气测量活动。此外，这种新仪器将在工业中找到许多应用（例如，泄漏检测，过程控制系统等），在农业中（例如，土壤、牲畜等的排放）和法医学（例如，爆炸物、麻醉品和其他化学物质等的检测）。
