Abstract : Spectra of the 6.3 micron water band were recorded by a balloon-borne spectrometer at 23.5 km altitude and over a wide range of sun elevations. Reduced in terms of transmittance they show an unexpected increase in humidity with increasing solar elevation angle. This feature is interpreted as a contamination by moisture carried at altitude by the package, the balloon, and associated train. An analysis based on this interpretation gives 0.0000105 as the corrected stratospheric mixing ratio above 23.5 km. (Author)
