Paper Abstract

In this paper we describe a new method which we referred to as the spectra accumulation method (SAM), for reconstruction of wind velocity and direction from measurement data of a scanning coherent Doppler lidar. The method does not require pre-estimation of the radial wind velocity. Numerical simulation based on virtual Doppler lidar instrument shows that in absence of turbulence SAM allows reconstruction of the wind velocity and direction from satellite lidar measurements with sufficiently high accuracy. In this paper we study the accuracy fo wind retrieval from lidar data by SAM when turbulent fluctuations of wind velocity are present. Simulation of wind retrieveal from space born scanning Doppler lidar data 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 of turbulent velocity fluctuations variance for different heights.
