We describe the four-laser airborne infrared (FLAIR) instrument, a tunable diode laser absorption spectrometer designed for simultaneous high-sensitivity in situ measurements of four atmospheric trace gases in the troposphere. The FLAIR spectrometer was employed during the large-scale airborne research campaign on tropospheric ozone (TROPOZ II) in 1991 and was used to measure CO, H(2) O(2), HCHO, and NO(2) in the free troposphere where detection limits below 100 parts in 10(12) by volume were achieved.
我们介绍了四激光机载红外（FLAIR）仪器，这是一种可调谐二极管激光吸收光谱仪，设计用于在对流层中同时对四种大气痕量气体进行高灵敏度原位测量。1991年，FLAIR光谱仪在对流层臭氧的大规模机载研究活动（TROPOZ II）中得到应用，用于测量自由对流层中的一氧化碳（CO）、过氧化氢（H₂O₂）、甲醛（HCHO）和二氧化氮（NO₂），在这些测量中实现了体积分数低于万亿分之100的检测限。
