Stratospheric mixing ratios of CH3D from 100 mb to 17mb (=15 to 28 km) and HDO from 100 mb to 10 mb (=15 to 32 km) have been inferred from high resolution solar occultation infrared spectra from the Atmospheric Trace MOlecule Spectroscopy (ATMOS) Fourier-transform interferometer. The spectra, taken on board the Space Shuttle during the Spacelab 3 and ATLAS-l,-2, and -3 missions, extend in latit...
