| Zusammenfassung |
| Here we describe the second version of Minnesota Earth System Model for Ocean
biogeochemistry (MESMO 2), an earth system model of intermediate complexity,
which consists of a dynamical ocean, dynamic-thermodynamic sea ice, and
energy moisture balanced atmosphere. The new version has more realistic land
ice masks and is driven by seasonal winds. A major aim in version 2 is
representing the marine silica cycle mechanistically in order to investigate
climate-carbon feedbacks involving diatoms, a critically important class of
phytoplankton in terms of carbon export production. This is achieved in part
by including iron, on which phytoplankton uptake of silicic acid depends.
Also, MESMO 2 is coupled to an existing terrestrial model, which allows for
the exchange of carbon, water and energy between land and the atmosphere.
The coupled model, called MESMO 2E, is appropriate for more complete earth
system simulations. The new version was calibrated, with the goal of
preserving reasonable interior ocean ventilation and various biological
production rates in the ocean and land, while simulating key features of the
marine silica cycle. |
