FIELD: meteorology.
SUBSTANCE: remote sensing of the atmosphere used to simultaneously determine the rate of dissipation of the kinetic energy of turbulence characterizing the intensity of wind turbulence, and structural constants. The invention can be used to determine the intensity of wind, temperature and optical turbulence in the atmosphere. The radial wind speed is measured by a coherent conical-scanning wind lidar probing a laser beam around a vertical axis at a given elevation angle. Based on the results of lidar measurements, the altitude-time distributions of the dissipation rate of the kinetic energy of turbulence, which characterizes the intensity of wind turbulence, are calculated using the azimuthal structural function method. Simultaneously with the measurement of the radial wind speed, the air temperature is measured with a given step at given times using a microwave radiometer, as well as atmospheric pressure. Taking into account the measured parameters, the altitude-time distribution of the structural constant characterizing the intensity of temperature turbulence, and the altitude-time distribution of the structural constant of the refractive index, characterizing the intensity of optical turbulence, are calculated.
EFFECT: simultaneous determination of the intensity of wind, temperature and optical turbulence in the atmosphere.
