A balloon borne Fast In situ Stratospheric Hygrometer (FISH) is described. It was designed to allow measurements during a controlled balloon descent at a rate of 2 to 10 m/s and at day time as well as during the night. These features guarantee wide application because they allow joint flights with other instruments on the same balloon payload. A first test flight of the instrument was carried out from Aire sur l'Adour (southern France) on Nov. 10, 1990. Because the instrument was launched under very humid conditions, strong outgassing from both balloon and payload was observed during ascent and float. As soon as a descent speed of 2 m/s was reached the stratospheric water vapor mixing ratio could be measured. The profile shows a minimum of about 2 ppmv at 60 hPa (19.5 km) and values increasing up to 6 ppmv at 15 hPa (28.5 km). It will be compared to the methane profile which has been measured on the same gondola.
