TI  - Optical and physical properties of stratospheric aerosols from balloon 
      measurements in the visible and near-infrared domains. III. Presence of aerosols 
      in the middle stratosphere.
PG  - 4086-95
AB  - The aerosol extinction measurements in the ultraviolet and visible wavelengths by 
      the balloonborne spectrometer Spectroscopie d'Absorption Lunaire pour 
      l'Observation des Minoritaires Ozone et NOx (SALOMON) show that aerosols are 
      present in the middle stratosphere, above 25-km altitude. These observations are 
      confirmed by the extinction measurements performed by a solar occultation 
      radiometer. The balloonborne Laboratoire de Meteorologie Dynamique (LMD) counter 
      instrument also confirms the presence of aerosol around 30-km altitude, with an 
      unrealistic excess of micronic particles assuming that only liquid sulfate 
      aerosols are present. An unexpected spectral structure around 640-nm observed by 
      SALOMON is also detectable in extinction measurements by the satellite instrument 
      Stratospheric Aerosols and Gas Experiment III. This set of measurements could 
      indicate that solid aerosols were detected at these altitude ranges. The amount 
      of soot detected up to now in the lower stratosphere is too low to explain these 
      measurements. Thus, the presence of interplanetary dust grains and 
      micrometeorites may need to be invoked. Moreover, it seems that these grains fill 
      the stratosphere in stratified layers.
