This paper describes a pulsed coherent Doppler lidar, recently created at the Wave Propagation Laboratory of the Institute of Atmospheric Optics SB RAS (WPL lidar). The WPL lidar was tested in atmospheric experiments. Comparison of the results of joint measurements of the radial velocity by the WPL lidar and Stream Line lidar showed their satisfactory agreement. From measurement of radial velocities by the WPL lidar at various azimuth angles (that is, with the use of the conical scanning), the height profiles of wind velocity and wind direction angle in the atmospheric boundary layer have been retrieved.
To determine the degree of anisotropy of wind turbulence from measurements by a Stream Line lidar during the experiment, we used a conical scanning by the probing beam, alternately setting the elevation angle of 35.3° and 60° after each scan. An experiment with such measurement geometry was carried out by us at the Basic Experimental Station of the IOA SB RAS in July 2018. Analysis of the measurement results at night in the presence of a low-level jet (LLJ) in the atmosphere showed that the variance (integral scale) of the horizontal component of the wind speed is 2.26 (3.4) times larger than the variance (integral scale) of the vertical component. In the central part of the LLJ, the integral scales of the horizontal and vertical components of wind speed are on average equal to 183 m and 54 m, respectively.
