Abstract

The Aircraft Laser Infrared Absorption Spectrometer (ALIAS) instrument is a high-resolution (0.0003 cm−1) scanning tunable-diode-laser spectrometer designed, tested, and flown more than 30 times on the National Aeronautics and Space Administration’s high-altitude ER-2 aircraft in the Airborne Arctic Stratospheric Expedition of 1991–1992. Using long-path infrared laser absorption spectroscopy to detect optical absorptions as small as 10−5, ALIAS provides fast, continuous in-situ measurements of key atmospheric gases, with gas detection sensitivities of tens of parts in 1012. With four lasers and detectors in a single liquid-nitrogen Dewar, simultaneous measurements of HCl, NO2, HNO3, CH4, and NO2 are made using laser sources at 3.4–8 μm, injected into a 1-m-long, 80-pass Herriott cell.
