“…Sodars or acoustic radars are widely used all over the world to investigate the structure and dynamics of the atmospheric boundary layer (ABL) [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. The principle of their operation is based on the effect of sound scattering by small-scale turbulent inhomogeneities of the atmosphere.…”

“…In the literature, including our papers, only results of measurements of individual turbulence characteristics are described. Many papers are devoted to measurements of the temperature and wind velocity structure characteristics [1][2][3][4][5][6][7]; results of acoustic sounding of the turbulent kinetic energy dissipation rate are presented, for example, in [8,9]; the wind velocity structure functions are considered in [10,11].…”

Abstract. Possibilities of sodar application for investigation of the spatiotemporal dynamics of three components of wind velocity vector, longitudinal and transverse structural functions of wind velocity field, structural characteristics of temperature and wind velocity, turbulent kinetic energy dissipation rate, and outer scales of temperature and dynamic turbulence in the atmospheric boundary layer are analyzed. The original closed iterative algorithm of sodar data processing taking into account the classical and molecular absorption and the turbulent sound attenuation on the propagation path is used that allows the vertical profiles of the characteristics of temperature and wind velocity field to be reconstructed simultaneously and their interrelations to be investigated. It is demonstrated how the structure of temperature and wind turbulence is visualised in real time.
