Example of frequency spectra of U up to 100 Hz during the ascent (A1) (left) and descent (D1) (right) of FLT16-05. The black lines show spectra after averaging the 10 spectra in gray lines. The red lines show the − 5/3 inertial subrange slope. The blue lines show the calculated slopes between 1.0 and 7.5 Hz
