Videos of wind data profiles showing how the wind characteristics vary with height across large rotors can be useful for understanding your wind farm site, whether operational or in the planning stage. This is particularly relevant to performance of very large offshore turbines where wind conditions vary significantly across the rotor, as well as for sites in complex terrain. Get in touch if you would like to obtain such a video for your own sites. We can use existing LIDAR or met mast data, or arrange new measurements as appropriate.
