Abstract:

The results of joint measurements of height profiles of speed and direction of the wind by a pulsed coherent Doppler lidar “Stream Line” and radiosonde RS92-SGP in Tomsk from 23 to 27 September 2013 are presented. It has been found out that from the lidar data, measured at elevation angle of 45 deg, the wind profiles are retrieved up to heights from 400 m to 1100 m, depending on aerosol concentration in the atmospheric boundary layer. It is shown that the correlation coefficient for velocity and direction of the wind measured by lidar and radisonde equals 0.97. Mathematical expectation and standard deviation of differences of wind velocity and direction estimates from data of the radiosonde and Doppler lidar are, respectively, 0.1 m/s and 0.7 m/s for velocity and 0.8 deg and 4 deg for direction of the wind.

Keywords:
