Abstract
Along with measurements of mean wind fields, Doppler lidars are used for estimation of the turbulence parameters. In particular, the attempts to use the Doppler lidars for measurement of the dissipation rate of the turbulent kinetic energy (epsilon) T and the wind field structure constant from estimations of mean spectrum width of Doppler signal are discussed. This approach is true for small sizes of lidar probe volume. If longitudinal size of probe volume (Delta) Z is comparable or exceeds the outer scale of turbulence LV this method cannot be used. We discuss the feasibility of estimation of dissipation rate from Doppler lidar data at arbitrary size of lidar probe volume.
