In November 2013, LLNL deployed two vertically-profiling, Doppler Laser Detection and Ranging (lidar) instruments at Enel Green Power North America?s 235 MW wind farm in Northern Oklahoma to collect wind measurements. The lidars were used to measure wake-free observations of the free-stream wind flow (i.e., inflow) for purposes of quantifying rotor-disk wind characteristics under varying atmospheric conditions. The measurements included horizontal wind speed, vertical wind speed, wind direction, and turbulence intensity, taken at a ~1 Hz sampling rate and averaged over 10-minute intervals. From these measurements we also calculated wind shear across the turbine rotor disk and turbulence kinetic energy (TKE).
