Fortran module that computes the vertical motion at the lowest level

[Liliputian_123]

Hello,
I am looking for the following equation in the wrf model:


According to this paper, Robinson and Businger 2019, this is how the lowest-level vertical motion in WRF is calculated.

Can anyone point me to the fortran module that computes this?

Thank you in advance!
I'll appreciate any help!

Hi,
I'm not certain, because the code is written differently than a simple equation, and this was all written many years before I joined the team, but I *think* the equation you're looking for is in dyn_em/module_small_step_em.F (line 1383 in V4.6.0). If that's not right, try searching in the dyn_em/ directory to see if you're able to locate it. If you still can't, I can try to reach out to someone else for guidance.
