Experimental data on auto– and cross–spectra of the backscattering coefficient fluctuations are presented for synchronous registration of three components of wind velocity, temperature, and backscattering coefficient in a local air volume at a height of 5 m. Measurements were carried out with an acoustic meteorological station and an aerosol laser radar. Obtained results have verified the differences between the autospectra of wind velocity fluctuations and backscattering coefficient fluctuations at stable thermal stratification and have shown different behavior of vertical and horizontal turbulent flows of heat and atmospheric aerosol depending on the thermal stratification.
