Short summary

This study uses a new type of observation of wind and turbulence to investigate the accuracy with which the German weather forecasting model predicts these variables in the lowest 600 m of the atmosphere. The model performs adequately during the day, but struggles with both wind and turbulence at night. This is important for wind energy planning and understanding how airborne particles are transported by the wind. The study suggests ways in which the model could be further improved.
