Popis:	In the report the spatiotemporal dynamics of three components of wind velocity vector retrieved from Doppler minisodar measurements in the atmospheric boundary layer is analyzed. Robust nonparametric methods of data processing based on the weighed maximum likelihood method (WMLM) are used for analysis. It is demonstrated that the efficiency (mean square error, MSE) of the adaptive estimates of the parameters of wind velocity components measured by the sodar based on the WMLM is much higher that the efficiency of the classical parametric estimates based on the LSM.
