Affected Releases - CESM1.2.z(Bugzilla 1776) - When running CLM45CNDV model (compset: ICLM45CNDV) and after running 400 years, there are no trees in the Amazon. ICNDV works all fine.The behavior has been attributed to Gordon's physiology changes to the model that improve the GPP simulation. This means that the dgvm needs retuning, and we decided not to proceed with such retuning at this time because we expect this dgvm to be replaced with Rosie Fisher's work in the not too distant future.
