Abstract

In this paper the numerical simulation results of the Doppler lidar measurements for high horizontal spatial resolution corresponding grid cell sizes of 1×1 km and 3×3 km are presented. It is shown that the variances, which characterize the measurement uncertainty of components of mean wind velocity, depend strongly on state of the atmospheric turbulence and the number and sizes of grid cell. Also the variances are the complex functions of the signal-to-noise ratio, VAD sector scan angle, elevation angle, and direction sensing. The measurement uncertainty of component of mean wind velocity U decreases with increasing cell number in the direction sensing of East and for horizontal spatial resolution of 1×1 km. But the measurement uncertainty increases with increasing cell number for resolution equal to 3×3 km. The variance for the component U is a maximum and the component V has a minimum uncertainty of measurement in the directions of North and South. The variance for the component U is a minimum and the component V has a maximum measurement uncertainty in the directions of East and West. The variance for the components U and V have the same values in the directions of North-East, North-West, South-East, and South-West.
