14 September 2016:

Two Whirlwind 1 lidars, installed on 8 April 2016 on a Siemens SWT-3.6-120 wind turbine in the offshore wind park RIFFGAT, were recovered after five months of successful operation.

The goal was to monitor meandering wake turbulences behind the rotor, a parameter of interest for a better understanding of wake effects in large wind farms, studied in the project GW Wakes at ForWind Center for Wind Energy Research.
