ACCESS-ESM

ACCESS ESM model

The ACCESS Earth System Model (ACCESS-ESM) is a fully-coupled global climate model that includes atmoshpere, land, ocean, sea ice, as well as ocean biogeochemistry and land biogeochemistry components, linked together by a coupler.
This means it can simulate both the physical climate and global biogeochemical cycles, in particular the carbon cycle.

ACCESS-ESM1.5

ACCESS-ESM1.5 1 is a fully-coupled climate model with land and ocean carbon cycle components. ACCESS-ESM1.5 was developed primarily to enable Australia to participate in the Coupled Model Intercomparison Project Phase 6 (CMIP6) with an ESM version.

Model components

ACCESS-ESM1.5 has an equilibrium climate sensitivity of 3.87°C for doubled CO2 concentration.
