This is a mathematical definition for Kolmogorov length scale, along with the NetCDF attributes.
Additional Information
[math]\displaystyle{ \eta=\left(\frac{\nu^3}{\varepsilon}\right)^{1/4} }[/math]
where [math]\displaystyle{ \nu }[/math] is the kinematic viscosity of the fluid and [math]\displaystyle{ \varepsilon }[/math] is the rate of dissipation of turbulence kinetic energy by viscous friction. It is the smallest length scale before viscous effects smoothen the velocity fluctuations.
