The processing of ADCP data to compute turbulent kinetic energy dissipation rates ([math]\displaystyle{ \varepsilon }[/math]) using the structure function technique can be divided into the following steps. The sub-steps include recommendations for deploying the ADCP, collecting, quality-controlling and processing the data to arrive at the [math]\displaystyle{ \varepsilon }[/math] estimates. No actual code is provided, rather these are the essential steps to be taken or implemented with your preferred software for pulse-pulse coherent ADCP data. Quality control measures are implemented at two stages: QA1 and QA2.

  1. Deploy ADCP appropriately to collect reliable turbulence data
  2. Apply quality-control on velocity time series data (QA1)
  3. Set structure function processing parameters
  4. Compute structure functions and dissipation estimates
  5. Apply quality-control on dissipation rates (QA2)
