Grid ENabled Integrated Earth System Model

Acronym:

GENIE

Liaise ownership:

no

Description:

The GENIE model is focused on long-term paleo-climate change, and the future long-term response of the Earth system to human activities. It includes modules of the atmosphere, ocean, sea-ice, marine sediments, land surface, vegetation and soil, ice sheets and energy.
The model is mainly used for:
• long-term (millennia) climate-variation simulations;
• investigating carbon cycles during deglaciation and the changes in vegetation and carbon storage during Holocene, a geological epoch which began approximately 10,000 years ago and continues in the present;
• long-term projections of climate change and carbon cycling.

Input variables:

Output variables:

GENIE’s core modules are:<br />
• IGCM (Intermediate General Circulation Model) Atmosphere model;<br />
• EMBM (Energy-Moisture Balance Model) Atmosphere model – generates estimates for surface air temperature and surface-specific humidity;<br />
• GOLDSTEIN Ocean model – generates estimates of ocean temperature and salinity;<br />
• Slab Ocean model - evolves the ocean surface temperature based on the flux balance at the surface;<br />
• Dynamic-Thermodynamic Sea Ice model – estimates ice thickness and ice area fraction variables;<br />
• Slab Sea Ice model - calculates the surface temperature based on the flux balance at the surf;<br />
• Efficient Numerical Terrestrial Scheme - dynamic vegetation and soil model with a single class of vegetation;<br />
• GENIE-land - land and vegetation model, which simulates the interactions between the land surface and the atmosphere and oceans. These interactions include energy exchanges (radiation, heat) and mass exchanges;<br />
• GLIMMER – land-ice model – models feedbacks between the ice and the rest of the climate system, such as albedo changes, ice elevation evolution and the fresh water resources;<br />
• GENIE-atchem - Atmospheric chemistry model - estimate atmospheric CO2, CH4 and N2O and conserve these compounds over the Earth system;<br />
• Biogem - Ocean Biogeochemistry model;<br />
• RokGeM - Land Surface Weathering model - estimates calcite and silicate weathering.<br />
