Abstract
There are many atmospheric trace gas species involved in the three catalytic cycles that contribute to stratospheric ozone depletion. The OH molecule is central to one of this cycles yet its concentration as a function of altitude is very difficult to measure in the stratosphere. The stronger rotational transitions lie at frequencies greater than 1500 GHz, significantly above the realm, of traditional submillimeter heterodyne instruments. Both Fabry-Perot and Fourier transform spectrometers have been used to observe OH in the atmosphere. Due to their inherent lower resolution these instruments can obtain atmospheric profiles only in a limb viewing geometry, thus they must be lofted above the stratosphere via balloons. This significantly constrains their seasonal and geographical survey capabilities. In this paper we Investigate the feasibility of utilizing a far infrared laser heterodyne instrument, operating aboard an aircraft, for the detection of OH and other relevant trace gas species in the stratosphere.
