MPAS-O is designed for the simulation of the ocean system from time scales of months to millenia and spatial scales from sub 1 km to global circulations.

MPAS-O has demonstrated the ability to accurately reproduce mesoscale ocean activity with a local mesh refinement strategy.

In addition to faciliating the study of multiscale phenomena within the ocean system, MPAS-O is intended for the study of anthropogenic climate change as the ocean component of climate system models.

MPAS-O is presently developed and maintained by the ocean model development team within the COSIM project at Los Alamos National Laboratory.

The primary sponsor for the development of MPAS-O is the Climate and Environmental Sciences Division within the Department of Energy.

This ocean model is being developed for use within the Department of Energy's Accelerated Climate Model for Energy (ACME).
