The accuracy of retrieval of the mean wind from lidar data by the method of variational spectrum accumulation (VSA) under conditions of wind-induced turbulence is studied. The analysis is performed by numerical simulation using the developed Virtual Instruments information-expert system. The method for simulation of inhomogeneous with height turbulent wind fields is described. It is shown that under conditions of wind-induced turbulence the accuracy of the VSA method decreases as compared to the case without velocity fluctuations, and, consequently, the height, up to which the mean wind can be retrieved from the spaceborne Doppler lidar data with the accuracy acceptable for further usage in weather-forecast models, decreases. At the same time, the accuracy of the VSA method turns out to be much higher as compared to that of the traditional method of wind velocity determination with prior estimation of the radial velocity.
