Segmenting datasets

Once the raw data has gone through QA/QC, then you must:

• Split the time series into shorter segments by considering stationarity, and the time and length scales of turbulence
• 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
• Evaluating stationarity, Taylor's hypothesis, etc ...
• Estimate surface wave velocities
• Calculate the mean flow past the sensor
