Description

The calculation of friction velocities over land neglects the contribution from the free convection velocity scale (w*) and the stability profile functions (Psi_M). It is unclear why u* isn't calculated directly from the surface momentum stress, as is done over sea. See IFS cy31r1 documentation for details.
