Methods to evaluate CaCO3 cycle modules in coupled global biogeochemical ocean models
evaluate CaCO3 cycle modules coupled global biogeochemical ocean
2014/12/19
The marine CaCO3 cycle is an important component of the oceanic carbon system and directly affects the
cycling of natural and the uptake of anthropogenic carbon.
In numerical models of the marine ca...
Adding a dynamical cryosphere to iLOVECLIM (version 1.0): coupling with the GRISLI ice-sheet model
Adding a dynamical cryosphere iLOVECLIM GRISLI ice-sheet model
2014/12/19
We present a coupling approach to and the first results of the GRISLI ice-sheet model within the iLOVECLIM-coupled climate model. The climate component is a relatively low-resolution earth system mode...

Semi-Lagrangian transport of oxygen isotopes in polythermal ice sheets: implementation and first results
Semi-Lagrangian transport oxygen isotopes polythermal ice sheets implementation first results
2014/12/19
Modelling the evolution of the Earth system on long timescales requires the knowledge and understanding of driving mechanisms, such as the hydrological cycle. This is dominant in all components of the...
A reduced-order modeling approach to represent subgrid-scale hydrological dynamics for land-surface simulations: application in a polygonal tundra landscape
reduced-order modeling represent subgrid-scale hydrological dynamics
2014/12/19
Existing land surface models (LSMs) describe
physical and biological processes that occur over a wide
range of spatial and temporal scales. For example, biogeochemical and hydrological processes res...
