something I ran into while testing WRF 4.8.0, specifically with the Noah-MP changes.
In WRF 4.8.0, the old Noah-MP namelist option opt_run is no longer viable. It looks like the change came in with the refactored Noah-MP v5.1.2 coupling, where opt_run was split into opt_runsrf and opt_runsub.
So older namelists that use:
opt_run = 3,
now need to be updated to:
opt_runsrf = 3,
opt_runsub = 3,
The issue is that this can cause real.exe to fail while reading the &noah_mp section, but the error message is not very clear unless someone knows to chase it through the registry or the GitHub commit history.
