Model Configurations

ACCESS Model Configurations combine separate domain-specific model components (e.g., atmosphere, land, ocean and sea ice) into a single unified model, generally using a special coupler program to represent the interactions between the various components of the system, which play a crucial role in the dynamics of the Earth System.

ACCESS links various model components through software called couplers. A coupler is a code specially adapted to handle communications between the various components.

Different ACCESS model configurations may use a subset of the core component models for atmosphere-only or ocean-only simulations or may replace component models to meet the needs of a specific application.
