Can the WRF model output the surface roughness length and friction velocity at each grid point in its results?

[xinyuchen]

I would like to obtain the surface roughness length and friction velocity in order to construct the logarithmic wind profile. Is it possible to directly retrieve these parameters from the output results of the WRF model?

The variable “UST” in the standard output is friction velocity.

I see. Thank you very much! Do you also know whether the roughness length can be extracted from the WRF output results?

While I haven't tried outputting roughness length yet, perhaps this discussion thread could be useful for your case.

Thank you very much! I will keep trying!

Hi , I want to get \tau_x , \tau_y :



but I don't know How to get it or related terms , Could you help me?
