StabilityCorrection

Value

Meaning

f(Richardson Number)

The aerodynamic resistance is estimated as a function of Richardson number.

f(Monin-Obukhov Length)

The aerodynamic resistance is estimated as a function of the Monin-Obukhov stability parameter ζ=(zref-d)/L. Richardsons number is transformed into ζ by an iterative procedure which may slow down the simulations. On the other hand, variations in surface roughness for momentum and heat is treated in a consistent way.
