Abstract
The Functionally Assembled Terrestrial Ecosystem Simulator (FATES) represents processes related to the demographics and dynamics of aboveground natural vegetation. It serves as a focal component of the Model-Experiment (MODEX) approach to the Next Generation Ecosystem Experiment (NGEE-Tropics). The Accelerated Climate Model for Energy (ACME) represents the vast super-set of processes of an earth simulation model. As such, it utilizes models such as FATES to simulate specific components of the earth system. Here we describe the process of coupling FATES into the ACME software framework, describe some of our testing methodologies, and evaluate some output of ACME-FATES simulations from scientific and software perspectives.
