This paper describes the airborne tunable laser absorption spectrometer, a tunable diode laser instrument designed for in situ trace-gas measurement in the lower stratosphere from an ER-2 high-altitude research aircraft. Laser-wavelength modulation and second-harmonic detection are employed to achieve the required constituent detection sensitivity. The airborne tunable laser absorption spectrometer was used in two polar ozone campaigns, the Airborne Antarctic Ozone Experiment and the Airborne Arctic Stratospheric Expedition, and measured nitrous oxide with a response time of Is and an accuracy ≤ 10%.
本文介绍了机载可调谐激光吸收光谱仪，这是一种可调谐二极管激光仪器，设计用于从ER - 2型高空研究飞机上对平流层下部进行原位痕量气体测量。采用激光波长调制和二次谐波检测来实现所需的成分检测灵敏度。该机载可调谐激光吸收光谱仪用于两次极地臭氧探测活动，即机载南极臭氧实验和机载北极平流层探险，并测量了一氧化二氮，其响应时间为1秒，准确度≤10%。
