Abstract: 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.
The MITgcm code and documentation are under continuous development. The last official release was called "Release1_patch8" and the current development is stabilizing in anticipation of a "Release2_beta" announcement. Both the last stable release and the current CVS contents can be obtained here.
