only C3 arctic grass in CLM45BGCDV

[zhangguangzhi]

Dear staff, I used CLM45BGCDV to simulate vegetation changes on the Qinghai-Tibet Plateau from bare land. In the spinupAD case, the model was repeated for 670 years using 850 years of forcing, but there was only one PFT of C3 arctic grass. The zip package is my lnd_in, datm_in, drv_in file. And I checked my forcing files and it didn't feel like there was a problem.

Unfortunately, as noted in this post, we no longer support the DGVM:

"The old CLM-dgvm was last documented in this paper using clm4/cesm1:
Evaluation of the new CNDV option of the Community Land Model: Effects of dynamic vegetation and interactive nitrogen on CLM4 means and variability
CK Gotangco Castillo, S Levis, P Thornton - Journal of Climate, 2012
I don't think that the CLM-dgvm worked very well (or at all) in later versions of the model.

The new CLM-dgvm is FATES. You can find corresponding documentation and articles online."

@slevis , anything to add here?

@zhangguangzhi
@oleson is correct. If you were motivated, you could probably figure out how to make the DGVM work correctly again, but we have not supported it for several years now.

Thanks for your response, I am now going to use FATES 'dynamic vegetation to solve my problem, but a bug appears that says it has been fixed in the latest version of CTSM. However, I have not been able to download other submodels in CTSM, can you provide a copy of the latest CTSM source code?
