Abstract
The application of robust methods of statistics to processing of data of minisodar measurements of vertical profiles of three wind velocity components at altitudes 5–200 m is considered in the report. The statistical characteristics of three wind velocity components obtained using nonparametric methods based on the weighted maximum likelihood method and classical methods are analyzed. Results of minisodar data processing showed that the standard methods of processing lead to considerable bias and low efficiency of estimations in comparison with the nonparametric WMLM estimations.
