Summary statistics from field observations. I, II, III: Refers to a unique stamen and its sampling interval (local time). H, stamen height (m); T, temperature (°C); Θ, clockwise angle with respect to north (deg.). , average wind speed (m/s); TI, turbulence intensity. u_RMS, v_RMS, w_RMS, root mean square of wind velocity in x-, y-, and z-directions (m s⁻¹), respectively.
