Abstract
In preparation for the ACME BGC series of coupled simulations, we have implemented models of biogeochemical and ecosystem dynamics with the MPAS framework within ACME. The ocean module is a port of the CESM package developed by Moore, etal (2004), with the addition of LANL-developed dynamic dimethyl sulfide (DMS) and explicit decomposition of dissolved organic carbon into specific macromolecular classes. The sea ice BGC is a new vertically resolved collection of reactions designed by Jeffery, Elliott, and Wang to be complimentary to the ocean formulation. As a result, we are able to pass constituents between models for studying truly coupled interactions. Since the ocean BGC is based on the CESM formulation, comparisons of ACME/MPAS results with CESM/POP and with data products can provide a baseline validation.
