Anemometer and strain gauged Tala kite wind data are analyzed with concurrent blade strain on a 600 kW wind turbine. While anemometer spectra drop at 1 Hz, the kite shows considerable energy up to several Hz. The rain flow count method identified discrete and nested cycles in the data. When registering a large amplitude cycle, the kite moved significantly from it`s no cycle position demonstrating that the kite actively seeks out and samples turbulence lumps over an area as opposed to a fixed anemometer. The kite simulated measured number of cycles and durations reasonably well while the anemometer failed.
