What is FATES?

FATES stands for the Functionally Assembled Terrestrial Ecosystem Simulator and is a module with fully open-source development:

FATES open-source

It is designed to operate in a “host” land surface model, which simulates:

But that’s not all…

FATES (in common with all land surface models that are part of ESMs) remains technically challenging to run.

Speaker Notes


But that’s not all…

Interesting science is at the interface of the input parameters, model processes and emergent outcomes.
