The current land perturbation scheme (lndp=2) needs to be updated to the Noah-MP land model for use in GFSv17.
Solution
Update the routine applying land perturbations to also work with Noah-MP.
At the same time, revise the namelist options for applying land perturbations to the regional system (HRRR), since these are currently confusing and sometimes use the land model as a proxy for a regional / global run.
