Doppler wind lidar plan position indicator scans at the offshore wind farm "Global Tech I" on 2018-10-11

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: 8.0 s scanner speed: 0.25 deg/s range gates: 1000 m : 50 m : 12000 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' time stamps in UTC time zon
