Changes made in GEOGRID.TBL while couple CLM to WRF

[Aanchal]

Hey everyone
I want to run WRF with CLM land surface model rather default Noah LSM. I am having query how to couple WRF with CLM.

Do i need to make some changes in parameters like leaf area index (LAI) in GEOGRID.TBL or directly give the number for land surface model " CLM " in WRF parameterization schemes.
If anybody knows, please try to get back here.
Thank you

Hi,
To use the CLM LSM, instead of Noah, you just simply use the following namelist setting in the &physics record
sf_surface_physics = 5

Hey Kwerner
A very thankyou for your response.

Along with the sf_surface_physics = 5, Don't i need to change the parameter like leaf area index in the GEOGRID.TBL while couple CLM to WRF.

Hi,
There shouldn't be anything you need to change in the GEOGRID.TBL, but, in addition to the sf_surface_physics setting, you do also need to set the following in namelist.input:

num_soil_layers = 10
