This primarily concerns already current and erected high-rise buildings (considering their continuously growing heights) [2] and unmanned aerial SSR69071 References automobiles (UAVs) in connection with their revolutionary development [3]. Wind transfers its energy towards the UAVs and changes their flight states, causing quite a few accidents about UAVs. The wind kinetic power flux density vector is also among the major characteristicsAtmosphere 2021, 12, 1347. https://doi.org/10.3390/atmoshttps://www.mdpi.com/journal/atmosphereAtmosphere 2021, 12,2 ofdetermining the energy possible of wind MX1013 Epigenetic Reader Domain turbines [4,5]. Inside the vector type, it’s represented by the product of the total kinetic power density by the wind velocity vector. The total kinetic power in the atmospheric boundary layer (ABL) and its imply and turbulent elements are estimated from measurements on the mean values and variances in the wind velocity vector elements making use of lidars [6,7], radars [8], and sodars [91], every having its personal benefits and disadvantages. It should really be noted that the refractive index of sound waves is about 106 occasions higher than the corresponding values for radio and optical waves, plus the sound waves extra strongly interact with the atmosphere; as a result, their benefits for evaluation and forecast of wind loading on objects inside the ABL are evident. This makes acoustic sounding with application of sodars–Doppler acoustic radars–an specifically promising method. The sodar information (extended time series of continuous observations of vertical profiles on the wind velocity vector elements and their variances) provide high spatial and temporal resolution. Statistically reliable profiles of wind velocity vector elements are accessible with averaging, as a rule, from 1 to 30 min. In addition, minisodars enable the vertical resolution to become improved up to 5 m. This enables 1 to analyze their spatiotemporal dynamics of minisodar information with high spatial and temporal resolution. Based around the foregoing, in [10,11] we utilised minisodar measurements to estimate the imply and turbulent kinetic energy elements at altitudes of 500 m. Even so, when retrieving the total wind kinetic energy inside the atmospheric boundary layer from minisodar information, we faced several complications. For starters, lengthy series of heterogeneous information comprised a big quantity of outliers and unknown distribution of final results of measurements. This necessitated preprocessing of huge volume of raw minisodar data with application of origina.
