Here is a summary of the provided article: ## Summary ### What has changed 1. **Deprecation of the dynamic global vegetation model (DGVM)**: The legacy 'CNDV' code that runs the CLM biogeochemistry model with the LPJ-derived dynamic vegetation model introduced in CLM3 is no longer scientifically supported, though it has not been technically removed from the model. 2. **Introduction of FATES**: The Functionally Assembled Terrestrial Ecosystem Simulator (FATES) is the actively developed DGVM for the CLM5. In essence, the article discusses the changes in the CLM5.0 model, specifically the deprecation of the previous dynamic global vegetation model (DGVM) and the introduction of the new FATES DGVM as the actively developed vegetation model for the CLM5 release.
