“…The measured data were split into multiple hourly time series to obtain converged statistics for the subsequent analysis (Hutchins et al, ; Liu, Bo, & Liang, ; Wang & Zheng, ). Our measuring height is between 0.9 and 30 m, which is approximately in the logarithmic region (Liu, Bo, & Liang, ; Liu, Wang, & Zheng, ; Wang & Zheng, ; Yang & Bo, ). Eleven CSAT3B anemometers were installed in a logarithmic manner in the vertical direction for z = 0.9, 1.71, 2.5, 3.49, 5, 7.15, 8.5, 10.3, 14.5, 20.9, 30 m. The friction velocity u τ and the aerodynamic roughness length z 0 were calculated by fitting the mean velocity profile through the least squares method based on the logarithmic law (Bagnold, ): where κ is the von Karman constant, typically equals 0.41.…”
