Abstract

A new method has been developed for estimating the wind turbulence parameters (turbulent energy dissipation rate and radial velocity variance) from measurements with a conically scanning pulsed coherent Doppler lidar (PCDL) for arbitrary values of the parameter μ that is the ratio of the average wind velocity to the linear velocity of the probed volume moving around the base of the scanning cone. The method was tested on data from atmospheric experiment in which a Stream Line PCDL and a sonic anemometer were used. It is shown that, unlike the previously used lidar method, for μ >1 , the new method gives estimates of the dissipation rate, which are in good agreement with the estimates of the corresponding values obtained from measurements with the sonic anemometer.
