Question about vertical nesting.

[dakyoung]

Is vertical nesting of U,V done by interpolation in wrf.exe or real.exe?
(In this case, do we interpolate based on input data?)
Or is it done through atmospheric mechanics or physical equations?

Hi,
If you are using the vertical refinement method, this is taken care of during real.exe. The code for this is in the file dyn_em/module_initialize_real.F.
