| Abstract | Project: CMIP7 Future scenario experiments. Exploration of the future climate under a (selected) range of possible boundary conditions. In CMIP7, the priority tier for experiments is conditional on whether you are doing emissions- or concentration-driven simulations. There is no way to express this in the CVs (nor time to implement something to handle this conditionality). This means that, for your particular situation, some experiments may be at a lower tier than is listed in the CVs. For example, the `vl` scenario is tier 1 for concentration-driven models and tier 2 for emissions-driven models. However, in the CVs, we have used the highest priority tier (across all the possible conditionalities). Hence `vl` is listed as tier 1 in the CVs (even though it is actually tier 2 for emissions-driven models). For details, please see the full description in the ScenarioMIP description papers. Produced by: The ACCESS Consortium brings together Australian institutions contributing to the Australian Community Climate and Earth System Simulator (ACCESS) and its submissions to the Coupled Model Intercomparison Project (CMIP). Participating organisations contribute to different ACCESS models and scientific activities, supported through a combination of institutional investment and Australian Government research infrastructure and research programs, together with international collaborations. (Using Model/Source: ACCESS-ESM1-6 with Experiment scen7-h) The model is an updated version of ACCESS-ESM1-5, as used for CMIP6 (Ziehn et al., 2020). Its dynamic components are the UK Met Office Unified Model atmosphere (v7.3) in a configuration similar to HadGEM2 including CLASSIC aerosols, with the CABLE land surface model (v3) including land biogeochemistry. The atmosphere is coupled to the MOM5 ocean with WOMBATlite biogeochemistry and CICE5 sea-ice using the OASIS-MCT coupler. Chemistry is prescribed including monthly mean, zonally-averaged ozone. Volcano forcing is prescribed as stratospheric optical depth as monthly means in four equal area latitude bands. Land-ice is represented by an ice tile in the land surface model. A grid-cell is either completely ice or ice-free and the ice tile distribution does not change in time. The main differences from ACCESS-ESM1.5 include corrections to how convective momentum transport had been applied in the atmosphere, a change to ocean albedo to better match observations, a correction to the passing of ocean carbon fluxes into the atmosphere, updates to improve energy and water conservation across the land and atmosphere, inclusion of 3 new plant functional types (c4 crops and two Australian tree types), improvements to the treatment of land-use change, updates to some of the land parameterisations or parameter values, the inclusion of a pseudo-iceberg scheme for distributing runoff from Antarctica and Greenland and a substantial update to ocean-biogeochemistry. Many aspects of the model infrastructure have also been improved to ensure greater provenance, better support for users and enhanced model throughput. A manuscript describing ACCESS-ESM1.6 is in preparation (Ziehn et al.). Experiment: CMIP7 ScenarioMIP High emission scenario - A scenario with emissions as high as judged to be plausible, based on assuming developments that include a rollback of current mitigation policies. This scenario is expected to result in forcings below SSP5-8.5. Run with prescribed carbon dioxide concentrations (for prescribed carbon dioxide emissions, see `esm-scen7-h`). CMIP7 is a project of the World Climate Research Programme (WCRP), providing climate projections to understand past, present, and future climate changes. It is part of the WCRP Earth System Modelling and Observations (ESMO) Core Project, which was formed to coordinate all modelling, data, and observation activities across WCRP and its key partners.
