Atmospheric Turbulence Detection in Three Dimensions by Means of a Multiple Beam SODAR.
Abstract
An acoustical remote sensor has been developed to image the three-dimensional structure of atmospheric turbulence in the atmospheric boundary layer. The system is designed to detect the evolution and decay of microscale turbulence structures, the motions of individual microscale eddies, and characteristics of the mean wind in the lower boundary layer. The methodology consists in illuminating roughly half a steradian of the boundary layer with a powerful acoustical interferometer antenna, recording the backscattered signal through multiple simultaneous beams, and analyzing the acquired data for turbulence intensity and Doppler wind velocity. A commercial (Remtech PA-3) sodar is available to serve as a standard against which to compare these measurements in the vertical beam.
