The far infrared (30-110 per cm) emission spectrum of the lower stratosphere has been measured from balloon altitudes with a high resolution (0.06 per cm) rapid-scanning Michelson interferometer on two flights in 1976. The quality and resolution of the spectra obtained from two altitudes have permitted a careful search for emission lines from environmentally important molecules such as HCl, NO2, OH, H2O2, and CO, among the more prominent and well-known features due to H2O, O3 and O2. Column densities have been determined for H2O and O3 and upper limit estimates have been made from tentative identifications of several other constituents. However, the large angular field of view observed by the instrument prevented the determination of concentration profiles from atmospheric limb scans to the horizon. The possible future directions of this technique are outlined on the basis of operating experience over a 6 year program. The viability of this method of monitoring the concentrations of minor constituents in the stratosphere is discussed with respect to other equivalent techniques.
