A Doppler Wind-LiDAR (WindCube WLS8-8 (Toch, 2013) from the manufacturer Leosphere, France) was installed at the island Heligoland (54° 10' 38,12"N,7° 53'30,90" E installed almost at sea level ) in the German Bight, North Sea, and operated continuously for a period of an entire year. For system specifications please refer to Toch (2013). The Wind-LiDAR was installed on the site of the Alfred-Wegener-Institute near the port of Heligoland. The terrain is flat for winds from south, south-west and south-east without obstacles that could affect the wind profile above 40 m. However, for north-west and north directions a plateau level of about 50 m exists, which could influence the wind at the lowest measuring heights. The Wind-LiDAR provided the vertical profiles of the wind speed components, measured by means of the Doppler Beam Swinging technique. Four lines of sight are sequentially scanned by a 1.54 µm pulsed fiber laser to perform the geometrical computation of the 3D wind vector components.

The installation and remote supervision of the wind lidar have been performed by Christian Krüger of UL International. The authors would like to thank Heino Peters, Andreas Schmidt, Helgo Denker, Eva-Maria Brodte and Karen Wiltshire for the opportunity to install the Wind-LiDAR at the site of the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research. ...
