COMPOSING THE DIURNAL CYCLE OF MIXING HEIGHT FROM SIMULTANEOUS SODAR AND WIND PROFILER MEASUREMENTS

Mixing heights have been determined independently from sodar and bound ary-layer wind profiler measurements carried out at the Meteorological Observatory Lindenberg of the German Weather Service between 1 June 1 994 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 evolv ing 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 dem onstrated to be a promising tool for continuously monitoring the mixin g height throughout its complete diurnal cycle.
