Results of synchronous measurements on meteorological parameter pulsations in the atmospheric surface layer

摘要

Experiments with the help of multi-parameter meter of turbulent micropulsations of wind speed components, temperature, humidity, pressure, and concentration of aerosol particles for the purpose of an experimental study of the lower atmosphere were conducted. The meter is a compact device, which combines acoustic meter of three component of wind speed and temperature, optical infrared measurer of absolute humidity micropulsations, sensors of temperature, pressure, and relative humidity, and an one-angle nephelometer of open type for measurements of pulsations of the aerosol scattering coefficient and evaluation of pulsations in the concentration of atmospheric aerosol. Dispersion of fluctuations of optical and meteorological parameters; autospectra fluctuations of wind speed, temperature, humidity and scattering coefficient; turbulent flows of momentum, heat and aerosol particles; the spectra of turbulent flows were calculated.
