Preparing ACCESS for CMIP6
The Australian Community Climate and Earth System Simulator (ACCESS) is a weather and climate model for Australia. ACCESS provided climate simulations for the World Climate Research Programme’s Climate Model Intercomparison Project – Phase 5 (CMIP5), which provided the climate projections that underpinned the fifth assessment report from the Intergovernmental Panel on Climate Change (IPCC).
Given its importance to Australia’s climate preparedness and resilience, ACCESS needs to be an internationally benchmarked, world-class global climate modelling capability that is significantly more accurate than other global climate models for the Australasian and Southern Hemisphere region. Participation in the next phase of the Climate Model Intercomparison Project (CMIP6) will provide this benchmarking. This participation also supports Australia’s effective management of climate risks and opportunities, and engagement with future climate assessments, including the IPCC sixth assessment report.
In this project we’re preparing the next generation ACCESS model for participation in CMIP6. This will provide a global benchmark to assess ACCESS’s performance and suitability for applications across the ESCC Hub.

This project is contributing to meeting the following climate challenges:
Through improvements to ACCESS’s simulation of processes controlling Australia’s rainfall, this project will enhance the quality of future climate projections that are available to water managers and planners.
This work will provide agricultural and environmental systems managers with better projections and climate information with which to make management decisions.
This project provides the underpinning climate modelling that is necessary for better understanding the feedbacks between climate and the carbon cycle in Australian future climate scenarios.
Projections of future climate from ACCESS will provide coastal planners with the information they need to make informed coastal planning and management decisions.
Projections of future climate from ACCESS will enhance our ability to project changes in the frequency and intensity of extreme climate conditions, which will better inform infrastructure planning.
