CynthiaBluteau (talk) 22:35, 28 October 2021 (CEST) I ended up repeating this info t this page on segmenting dataset because I thought this current page was all QAQC related. Like checking if the spectra were dominated by noise via calculating spectral slopes. Doing some motion correction. Some surface-wave related checks or checking for odd vibrations.
Once the raw data has gone through QA/QC, then you must:
- Split the time series into sections of appropriate length based on stationarity
- Rotate the measurements into the frame of reference of the mean flow
- Determine the contribution of the mean flow versus turbulence to the velocity field
- Calculate the mean flow past the sensor
