Take advantage of plantation forests in CMIP7 LUH3 in ctsm6.1?

[ekluzek]

The CMIP7 LUH3 data has plantation forests separated out from secondary forest. This is something that we should take advantage of at some point.

This was pointed out by @lawrencepj1 here:

This needs to be done at one of the next minor version updates of CTSM beyond ctsm6.0.0, so possibly in ctsm6.1.

But, of course just adding it on the surface dataset isn't the only thing, it's adding the scientific ability to handle them. Likely this would be something that we'd want the FATES model to handle for us.

So can people with interest in this comment with their thoughts on how this should be handled scientifically?

From the software angle this could be handled in the following steps:

• Add it to the rawdata PFT files for input into mksurfdata_esmf, but assign to secondary forest in the surface datasets
• Add to to the surface and landuse.timeseries datasets, but assign to secondary forest in the model
• Add the ability to handle plantation forests, but treat them identically to secondary forest, but on their own patch
• Start adding in capability to manage planting and harvest
