Abstract:
sensor: Doppler Wind Lidar System Leosphere Windcube200S, Serial nr. WLS200S-024
unit: radial speed/m/s, cnr/dB, range/m, azimtuh angle/deg, elevation angle/deg
scan: continuous azimuthal scan (plan position indicator, PPI), time stamp and azimuth angle set at end of interval.
acquisition time per beam: 2.0 s
scanner speed: 1.0 deg/s
range gates: 500 m : 35 m : 8000 m (minimum : step : maximum)
pulse length: 400 ns
accuracy:
azimuth angle: north correction performed using reflections on neighbouring turbines (hard targeting), resulting error <0.1 deg
elevation angle: system aligned on the TP with resulting error <= 0.1 deg. additionally platform movements of the TP during turbine operation of up to 0.1 deg.
Geolocation
54.4920176777417 6.32947300850505, 24.6 m above MSL (mean sea level)
Lidar system placed on the transition piece (TP) of wind turbine GT58 in the offshore wind farm 'Global Tech I'
