Abstract

Statistical analysis of sodar measurements of wind velocity components in the atmospheric boundary layer (ABL) shows that data samples consist of nonuniform observations with unknown distributions. In the report, a modified nonparametric pendular truncation method implemented in a modified pendular truncation algorithm (MPTA) is suggested that allows one not only to detect, but also to select anomalous observations in minisodar data samples. The MPTA is tested on model examples. Based on the MPTA, sodar measurements of three wind velocity components in the ABL are censored, and their correlation coefficients and autocorrelation and structure functions are calculated. The calculated functions are compared with classical sample estimates.
