After the initial round of data QA/QC, there are three stages to estimating the turbulent dissipation rate:
- Conduct further QA/QC specific to spectral analysis
- Compute the spectra with sufficient degrees of freedom to get a statistically robust
- Estimate the mean flow past the sensor and if applicable the surface wave contributions to choose the appropriate inertial subrange model for spectral fitting.
- Identify the likely wavenumbers of the inertial subrange to estimate
