Spectroscopic measurements using tunable laser heterodyne spectrometers in the 3–30 micron range of the spectrum have the potential to measure the vertical profiles of tenuous gas molecules in the atmosphere with ultra high spectral resolution (∆υ ≤ 0.001 cm-1) and high sensitivity [1]. At the NASA Langley Research Center (LaRC), the technology and system level development for demonstrating the “technology readiness” of this technique has been pursued for some time, and a major activity has included technology development of reliable tunable semiconductor lasers [2], laboratory research in the fundamental noise sources of the heterodyne system [3], laboratory measurements of spectroscopic parameters with ultra high spectral resolution [4, 5], sensitivity analyses for potential applications [6] from space and balloon platforms, and development of a Laser Heterodyne Spectrometer (LHS) experiment to measure trace species in the atmosphere from the NASA CV-990 Airborne Laboratory [7]. The experimental flight demonstration is currently scheduled for implementation in the first quarter of fisical year 1983.
