Description of changes

Review of Tech Note section 2.29: Dynamic Global Vegetation and FATES

Specific notes

Added a section on reduced complexity modes and supported configurations.

Contributors other than yourself, if any: @wwieder

CTSM issues resolved or otherwise addressed, if any: Resolves #3875

Requirements before merge:

• I have followed the CTSM contribution guidelines.
• I have reviewed relevant parts of the CLM documentation Tech Note or User's Guide to determine if anything needs to be changed or added. If it does, describe:
• This PR either (a) does not create a need to update the documentation or (b) includes required documentation updates (see guidelines for contributing documentation). Which?:

[wwieder]

I might encourage a few more citations of more recent FATES papers and a quick summary of how CLM-FATES is different than vanilla CLM could be helpful, but otherwise this looks good. I'll approve this but happy to take another look if needed.

Thanks for the suggestions @wwieder. I made all the updates you suggested, please take a look and see what you think.

@adrifoster I can do the final review and let @wwieder off the hook :-)

[slevis-lmwg]

@adrifoster thank you for getting this ready and @wwieder thank you for the first review. I have minor corrections to contribute, and I can push them easily myself :-)

[slevis-lmwg]

I will work on correcting the build-fail.

@adrifoster this is ready to merge as far as I am concerned, but I will let you make the final decision.
