Measuring Obukhov length

[ashwinvis]

Suggestion from @vezeli

Here is an idea for you if you have the time and interest to follow it... When you have your LES result you could look at G/P (ratio of buoyancy production and shear production) this should give value of Obukhov length scale, than you can compare it with the value obtained from the standard definition of Obukhov length. The difference is quite substantial because in one case you estimate the Obukhov length from surface scaling properties while in the other formulation you use turbulence fluxes throughout the atmospheric boundary layer 🤓

This can be checked when we do stable ABL simulations.
