The stratospheric water vapor mixing ratio altitude profile has been derived from spectral observations of the downward night emission from the pure rotation water vapor lines in the 24 - 29 micrometers region of the spectrum. The data were obtained using a balloon-borne spectral radiometer with about a 2 cm resolution. The observed radiances have been fitted to line by line - layer by layer radiance calculations, from which the water vapor mixing ratio between 10 and 30 km has been derived. The resulting mixing ratio altitude profiles from both flights show a broad minimum around 15 km and a broad maximum around 25 km.
