A field campaign involving balloon borne soundings and a ST radar (PROUST), both allowing high resolution measurements within the lower stratosphere, was conducted during April 1998 in St. Santin (south of France). One objective of this campaign was to characterize the small scale turbulence of the atmosphere from simultaneous and almost co-located observations. The purpose of this communication is to put forward some aspects of the supply of high resolution in situ measurements regarding to the interpretation of the radar data. First, the radar calibration appears correct. Second, the turbulent events seems to be severely under sampled by radar, likely because of the ground echo. On an other hand, high resolution in situ measurements show that classical PTU soundings are not sufficient to characterize the background (or reference) state of the atmosphere (for turbulence studies at least). As a consequence, the Brunt-Väisälä frequencies evaluated by classical soundings (or by model outputs), which are needed to infer tubulence parameters from radar measurements, should be considered in fine as a random parameter.
