Segmenting datasets
From Atomix
Once the raw data has gone through QA/QC, then you must:
- Split the time series into shorter segments by considering:
- time and length scales of turbulence
- stationarity
- [Taylor's frozen turbulence| Taylor's frozen turbulence hypothesis], etc ...
- determine how (or if at all) missing samples should be replaced
- Determine the contribution of the mean flow versus turbulence to the velocity field
- Rotate the measurements into the frame of reference of the mean flow
- Estimate surface wave velocities
- Calculate the mean flow past the sensor
