Abstract
The infrared emission from minor constituents in the lower stratosphere has been measured using a balloon-borne cryogenic Fourier spectrometer. A liquid-nitrogen cooled interferometer spectrometer with liquid-helium cooled Si:Ga detectors has recorded selected portions of the thermal emission spectrum from $650-2000 cm^{-1}$ with an apodized resolution $0.03 cm^{-1}$. Species identified to date include $CO_{2}, O_{3}, H_{2}O, CH_{4}, HNO_{3}, N O NO_{2}, NO, ClONO_{2}, CCl_{3}F$, and $CF_{2}Cl_{2}$. A tentative identification of $N_{2}O_{5}$ in the $1230 - 1270 cm^{2-1}$ redion has been made.
