(a) Time series of the vertical wind component measured by the UP during calibration at a constant altitude close to the surface and (b) power spectral density for this time period on 15 July 2020. Both subplots show the raw wind speed as measured by the sonic anemometer ws (blue), and motion-corrected vertical wind velocity wE without (orange) and with (green) correction of the installation angle offsets between sonic and IMU. The green lines represent the data of the published dataset.
