Composing the diurnal cycle of mixing height from simultaneous sodar and wind profiler measurements

Mixing heights have been determined independently from sodar and boundary-layer wind profiler measurements carried out at the Meteorological Observatory Lindenberg of the German Weather Service between 1 June 1994 and 6 July 1994. Good agreement between both systems was found for mixing height values between about 250 m and 700 m, i.e., in an evolving convective boundary layer. Considering the typical sounding ranges of the sodar (50 m up to 800 m) and of the wind profiler (200 m up to higher than 3000 m), simultaneous operation of the two systems is demonstrated to be a promising tool for continously monitoring the mixing height throughout its complete diurnal cycle.
