I'm not aware of any nudging capability in CLM. But there is an option to prescribe soil moisture. See this post for information:
Hi everyone, I am going to carry out an experiment setting surface soil moisture as prescribed values at a specific domain. It is very similar to the Pacific pacemaker experiment which is usually applied in POP. I know how to modify on POP, but I am kind of new to CLM. Are there any documents...

Hi Oleson,
I designed a case which will run for one year in F2000climo in CESM2. The resoluton is set as f09_f09_mg17.
Following your suggestion, I only set "use_soil_moisture_streams = .true. ". I got the following error in the file lnd.log.7104048.231027-181639:

Any hints would be helpful! Thanks in advance!
