CMIP7 data availability

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.).
