Remote Measurements of Boundary Layer Velocity Parameters by Monostatic Lidar.

Abstract

Wind velocity parameters in the plaetary boundary layer are measured using spatial inhomogeneities in the natural aerosol content as tracers. Lidar measurements of these spatial inhomogeneities are correlated in time and space to remotely estimate the mean speed, direction and the rms speed variance of the wind velocity. Aerosol inhomogeneities with horizontal dimensions of 60m-0.1km were found to be efficient tracers of the wind. The coherence between spatially and temporally separated lidar profiles of these spatial aerosol inhomogeneities is used to determine the perpendicular components along and across the beam pattern of the horizontal wind velocity. Comparisons between lidar horizontal wind measurements with tower anemometers and pilot balloons show that lidar can remotely sense the boundary layer flow.
