A new SODAR technique has been developed that uses pulse compression techniques to make boundary layer measurements of wind with very high spatial and temporal resolution. At a range of 2km the typical spatial resolution is 4m with a temporal resolution of 3.5 minutes for measuring wind speeds from 0.0m/s to over 30m/s. Ê

The basic theory and operation of the system will be presented together with measurements of horizontal and vertical wind that illustrate the capability of the system. Measurements of Kelvin-Helmholz waves and aircraft wake vortices will also be presented. The potential of the system to be expanded to make measurements of virtual temperature, turbulent viscosity and TKE/EDR will be discussed. Areas of the system and applications requiring additional research will be outlined. Ê

The potential of this system to improve our understanding of the boundary layer and provide commercial applications in the areas of urban meteorology, wind farm optimization and airport capacity and safety enhancements will also be presented.
