Estimate epsilon

Once the spatial-spectral estimates have been computed, the following steps are recommended for obtaining epsilon:

1. Establish the most likely wavenumber range for the inertial subrange
2. Fit the spectrum of all three velocity components with the appropriate inertial subrange model
3. Compute various quality statistics based on the estimated [math]\displaystyle{ \varepsilon }[/math]:
   • Anisotropy

• • Spectral slope (?)
