Abstract
The optical Doppler technique of the ground-based remote sensing of the thermospheric wind is reviewed with special consideration given to the admissibility of the assumptions made in the reduction of data from a single station. Examples of observations made in the Auroral Zone indicating substantial wind gradients and vertical winds are given. Such observations indicate the importance of small scale disturbances in the Polar thermosphere. Data from three stations in the Northern Auroral Zone and Polar Cap show how the flow pattern, the wind speed and its variation with magnetic activity strongly suggest that the main source of the momentum of the Polar Thermosphere is the convecting ions in the ionosphere.
