This mostly concerns currently current and erected high-rise buildings (thinking of their continuously increasing heights) [2] and unmanned aerial automobiles (UAVs) in connection with their revolutionary improvement [3]. Wind transfers its power to the UAVs and modifications their flight states, causing many accidents about UAVs. The wind kinetic power flux density vector is also one of many key characteristicsAtmosphere 2021, 12, 1347. https://doi.org/10.3390/atmoshttps://www.mdpi.com/journal/atmosphereAtmosphere 2021, 12,2 ofdetermining the energy prospective of wind turbines [4,5]. Within the vector type, it truly is represented by the item with the total kinetic energy density by the wind velocity vector. The total kinetic energy within the atmospheric boundary layer (ABL) and its imply and turbulent components are estimated from measurements from the imply values and variances on the wind velocity vector elements making use of lidars [6,7], radars [8], and sodars [91], every single getting its own positive aspects and disadvantages. It must be noted that the refractive index of sound waves is about 106 occasions higher than the corresponding values for radio and optical waves, as well as the sound waves far more strongly interact together with the atmosphere; therefore, their benefits for Thiamine monophosphate (chloride) (dihydrate) Biological Activity evaluation and forecast of wind loading on objects within the ABL are evident. This makes acoustic sounding with application of sodars–Doppler acoustic radars–an specially promising method. The sodar data (lengthy time series of continuous observations of vertical profiles from the wind velocity vector elements and their variances) supply high spatial and Antipain (dihydrochloride) Cancer temporal resolution. Statistically trusted profiles of wind velocity vector components are accessible with averaging, as a rule, from 1 to 30 min. In addition, minisodars enable the vertical resolution to become enhanced up to five m. This enables one to analyze their spatiotemporal dynamics of minisodar data with higher spatial and temporal resolution. Based on the foregoing, in [10,11] we applied minisodar measurements to estimate the mean and turbulent kinetic power components at altitudes of 500 m. Even so, when retrieving the total wind kinetic energy in the atmospheric boundary layer from minisodar data, we faced a variety of problems. First of all, lengthy series of heterogeneous data comprised a big variety of outliers and unknown distribution of benefits of measurements. This necessitated preprocessing of significant volume of raw minisodar data with application of origina.
