Abstract:

Presented in this paper are the equations derived for estimating standard errors and 90% confidence intervals in sodar measurements of the turbulence intensity and anisotropy of the wind field. The equations apply to any of the three-channel sensing scheme. Two (direct and indirect) methods of constructing the processing algorithms are also presented. The use of these equations allows one to estimate the degree of uncertainty in the data obtained, that is, to correctly interpret the results of acoustic sensing of the atmosphere. Vertical profiles of dynamic turbulence parameters are determined from sodar data using these equations.
