The first flight of the balloon-borne instrument SPIRALE, took place near Gap (France) in June 1999. SPIRALE aims at measuring the concentration of stratospheric species. The scientific objectives of this experiment are composition, photochemistry and small scale dynamics, through high rate, in situ and simultaneous measurements of several atmospheric species. The detection technique is based on tunable diode laser absorption spectroscopy in the mid-infrared. We report here the results of the first flight of SPIRALE. The expected performances are demonstrated, despite some problems with different components of the instrument. After correction of these problems by improvements in the real time control of the instrument, SPIRALE is now ready to be used in satellite validation programs (ODIN and ENVISAT), as well as for its specific scientific objectives. We also discuss new possible improvements, in order to decrease the detection threshold for low abundance stratospheric species.
