ACCESS-ESM1.6 for the CMIP7 Assessment Fast Track

Author Information: Tilo Ziehn (on behalf of the development and evaluation community)
Affiliation: CSIRO Environment, Aspendale, Australia
1 Introduction and scientific context
The CMIP7 Assessment Fast Track is aligned with the IPCC and other national and international climate assessments. Participation in the Fast Track therefore requires a model version that can deliver simulations results within this timeline. Australia’s submission to the Fast Track with a new Earth System Model version, ACCESS-ESM1.6, is based on our successful CMIP6 contribution with ACCESS-ESM1.5.
2 Methodology/project summary
This talk will highlight the new developments that have gone into ACCESS-ESM1.6 including an assessment and evaluation of performed simulations mainly focussed on the carbon cycle and biogeochemistry. An overview of targeted experiments as part of the CMIP7 DECK (entry requirement) and Assessment Fast Track will be provided including opportunities for the community to contribute.
3 Results
ACCESS-ESM1.6 provides an updated and improved Earth System Model version while maintaining its computational efficiency. First results will be presented from the pre-industrial control run in both concentration and emissions driven mode including comparison against ACCESS-ESM1.5 results and observations-based products across a number of key variables. Depending on availability, first results from other idealised experiments will also be presented.
4 Audience
Australian research community, policy and decision makers, next users and end users
