Abstract
Here we present a model system that enables the dynamics, transport and competitive acquisition of nutrients between demographic vegetation, soil mineral surfaces and microbial decomposers in the Energy Exascale Earth System Model (E3SM). This system is achieved through the coupling of nutrient dynamics in the Functionally Assembled Terrestrial Ecosystem Simulator (FATES) with the E3SM Land Model. Nutrient dynamics in FATES is designed with an emphasis on modularity and extensibility to facilitate the addition and comparison of new hypotheses. FATES can also be coupled with different soil biogeochemical models in ELM. The work reported here is an explanation of how FATES-ELM is coupled, as well as a demonstration of its current status.
