Laser-acoustic investigations of turbulent flows of aerosol particles in the atmospheric surface layer

摘要

Abstract: In this paper experimental and theoretical results on the investigation of the statistical properties of the atmospheric aerosol by the laser sounding method and by means of the acoustic meteostation are presented. Mathematical processing of data allowed to calculate turbulent flows of pulse, heat, and aerosol in the surface air layer. The presence gradient measurements was allowed to define scales for the measurement of velocity, temperature, specific content of aerosol particles and a scale of Monin-Obukhov length, and also to estimate according coefficients of the turbulent exchange for pulse, temperature, and atmospheric aerosol. !19
