MOBILE HIGH-FREQUENCY MINI-SODAR AND ITS POTENTIAL FOR BOUNDARY-LAYERSTUDIES

After a short review of the history of the mini-SODAR, the differences between conventinal SODAR and mini-SODARs are discussed. The backgrou nd for the interpretation of the turbulent structure parameters are gi ven. In view of existing mini-SODAR systems, some design criteria for portable systems are presented. The limitations in minimum range, vert ical resolutions and velocity resolution are discussed. Results from a n Arctic boundary-layer experiment, where three monostatic systems are used on a small scale, show the potential of its application. In view of other applications, future developments are presented.
