Can WRF-CLM model carbon flux?

Hello WRF community!

I've got a seemingly straightforward question: does the preloaded version of CLM4 (sf_surface_physics = 5) allow for the simulation of biogeochemistry, or at least NEE, GPP, NPP, etc.? I have recently tried going through the motions to couple WRF with CTSM, following this guide. Despite the project being mostly abandoned by CTSM staff, I was able to get fairly far in the process, but after working for >3 months to get this set up, I hit an error that was never addressed, and I believe it is time to give up.

This said, for my master's research, I am trying to simulate how a large clearcut alters mesoscale atmospheric fluxes and convective cloud development, and how this could impact how neighboring vegetation communities process and cycle carbon. Given that I am in an Ecology program, this last piece is key to my research, so I need a dynamic land surface model that is coupled with WRF to simulate carbon fluxes. While the revamped Noah-MP appears to be a reasonable option for this line of inquiry, I am concerned about the efficacy of the carbon simulations, particularly in comparison to those found in the CLM models. CLM puts greater emphasis on whole-plant phylogeny and physiology, which is far preferred by plant and ecosystem ecologists.

So, getting back to my question: is CLM4 a viable candidate for this type of research? If so, are there namelist parameters associated with the model that would allow for the simulation of complex biogeochemistry? I would greatly appreciate the guidance from you all. :)

Best regards,
Carter
 
Carter,
I am not an expert on CLM, and sorry that I don't have an immediate answer to your question.
Dr. Jiming Jin from Utah State University coupled CLM with WRF years ago. Probably you can contact him to get more information.
