ACCESS is a family of related models, configured for specific applications, to meet operational and research needs from weather forecasting to climate projections.

ACCESS is built from core component models:

  • UK Met Office Unified Model (UM) for the atmosphere
  • Community Atmosphere Biosphere Land Exchange (CABLE) model for the land
  • US NOAA/GFDL Modular Ocean Model (MOM) for the ocean
  • LANL CICE model for sea-ice.

Additional modules support biogeochemistry and atmospheric chemistry.

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

For a detailed summary of ACCESS, please review the follow presentation by the ACCESS group leader Rachel Law, prepared for the 2019 CLEX Winter School:
