Abstract

A series of experiments was carried out using a multi-parameter meter of turbulent micropulsations of the components of temperature, humidity, pressure, wind speed and concentration of aerosol particles in order to experimentally study the lower layers of the atmosphere. The meter is a compact device that combines an acoustic meter of three components of wind speed and temperature, an optical infrared meter for micropulsations of absolute humidity, sensors of temperature, pressure, and relative humidity, as well as an open-type one-angle nephelometer for measuring pulsations of the aerosol scattering coefficient and estimation of fluctuations in the concentration of atmospheric aerosol. The accumulation of data on the turbulent characteristics of various surface meteorological parameters was carried out in the course of measurements. The variance of fluctuations of optical and meteorological parameters, autospectra of fluctuations of wind speed, temperature, humidity and scattering coefficient, turbulent fluxes of measured substances were calculated.
