Results from a three-month intercomparison of boundary-layer wind profilerand solar wind measurements at Lindenberg, Germany

Intercomparison experiments with a wind profiler and a Doppler sodar have b een performed at the Meteorological Observatory Lindenberg of the German We ather Service in summer, 1994, and in autumn, 1995, over a total period of about three months. The paper presents selected results of the wind measure ments performed with the two systems. Sodar and wind profiler are shown to complement each other quire well. Therefore, a combination of both is a pro mising tool for continuous, high-resolution measurements of the wind profil e. A problem to be solved is the construction of composite wind profiles wh en the measurements with the two systems disagree in the height range of ov erlapping, Measurements of the vertical velocity are difficult to assess du e to their small absolute values. Long-term averages of the vertical veloci ty show slightly negative values, especially for the wind profiler. However , similar signatures have been found in the vertical velocity time series d uring frontal passages or during well-developed convection.
