Abstract
In this paper we study the accuracy of wind retrieval from lidar data by spectra accumulation method (SAM) when turbulent fluctuations of wind velocity are present. Simulation of wind retrieval from space borne scanning Doppler lidar data by this method we carry out based on the real data of German Weather Service (GWS). For simulation of small scale turbulent fluctuations of the radial wind velocity we use GWS height profiles of zonal and meridional components of mean wind, temperature and turbulent diffusion coefficients of momentum and heat. The error of retrieval of wind velocity and direction from lidar data is calculated in dependence on turbulent velocity fluctuations variance for different heights (signal to noise ratios). This study was supported by the Russian Foundation for Basic Research (Grant No00-05-64033).
