Abstract:

We present here some experimental results of the investigation into the potentialities of a cw Doppler lidar in measuring the turbulent energy dissipation rate. It is shown that at small size of the volume sounded the dissipation rate can be determined with a good accuracy from the lidar measurements of both the mean square of the Doppler spectrum width and the temporal structure function or the wind velocity range. It has been found that at large size of the volume sounded and small angles between the wind direction and the sounding beam axis the structure function is directly proportional to the time shift and the wind velocity range measured by the lidar is inversely proportional to the squared frequency.
