MPIOM

The Max- Planck- Institute ocean model (MPIOM) is the ocean- sea ice component of the Max- Planck- Institute climate model (Roeckner et al., 2006; Jungclaus et al., 2006).

MPIOM is a primitive equation model (C-Grid, z- coordinates, free surface) with the hydrostatic and Boussinesq assumptions made. It includes an embedded dynamic/ thermodynamic sea ice model with a viscous- plastic rheology following Hibler (1979) and a bottom boundary layer scheme for the flow across steep topography. A model description can be found at Marsland et al. (2003).

The standard configuration (GR15) uses a curvilinear orthogonal bipolar grid with poles over Greenland and Antarctica. The horizontal resolution gradually varies between a minimum of 12km close to Greenland and 150km in the tropical Pacific. It has 40 vertical levels, with 20 in the upper 600m. The model time stepping for tracers and velocity is formulated semi- implicitly with a time step of 4320s.

HAMOCC

HAMOCC is a sub-model that simulates biogeochemical tracers in the oceanic water column and in the sediment. It is set up as a subroutine of MPIOM, but can be interfaced to any Ocean General Circulation Model.  All biogeochemical tracers are fully advected and mixed by the hosting OGCM. The biogeochemical model itself is driven by the same radiation as the OGCM to compute photosynthesis. Temperature and salinity are used to calculate various transformation rates and constants e.g., for solubility of carbon dioxide.
