Application of acoustic sounding to estimating diffusion in an atmospheric boundary layer / Bryan R. Kerman. : En57-65/76-2E-PDF
"An acoustic sounder system can be configured to provide estimates of the vertical profile of velocity and the dissipation rates of kinetic and potential energy. A method based on the concepts of boundary-layer similarity theory is outlined by which the characteristic velocity in a freely convective boundary layer is deduced from the inversion height and a combination of any two of the mean wind in the layer, the dissipation rate of turbulent kinetic energy, and that of turbulent potential energy near the inversion. These values, in conjunction with the mean velocity, are used to establish the normalized heights, downwind and cross-wind distances, and cross-wind integrated concentrations. The normalized lateral and vertical standard deviations are then deduced from empirically established laboratory relationships for nonbuoyant particulates. Preliminary analysis indicates a similar methodology may be applicable to the stable boundary layer"--Abstract.
