The MITgcm (MIT General Circulation Model) is a numerical model designed for
study of the atmosphere, ocean, and climate. Its non-hydrostatic formulation
enables it to simulate fluid phenomena over a wide range of scales; its adjoint
capability enables it to be applied to parameter and state estimation problems.
By employing fluid isomorphisms, one hydrodynamical kernel can be used to
simulate flow in both the atmosphere and ocean. http://mitgcm.org/
