This table summarizes the current status of DECK and Fast Track experiments using ACCESS-ESM1.6.
Notes:
- See Airtable - CMIP AR7 Fast Track experiment viewer (public) for experiment details
- ‘Run status’ is given as NxM yr where N is the number of ensemble members that have been completed and M is the number of years required for the submission (some experiments may have run a few extra years).
- Raw model output is available here: /g/data/p73/archive/CMIP7/ACCESS-ESM1-6/production in the directory listed under ‘p73 location’. Access to p73 can be requested through MyNCI.

Concentration-driven idealised simulations: global mean surface air temperature
The temperature anomaly is calculated as the difference from the mean of the first 100 years of the piControl simulation.
The control simulation (run under constant 1850 conditions) (black) shows stable global mean temperature as expected. Temperature increases rapidly (red) when atmospheric CO2 is instantaneously quadrupled. The temperature increase is approximately linear when CO2 is increased by 1% per year (blue). In the case where only the biogeochemistry is forced with the increasing CO2 (green), the temperature is close to that of the control run. In the case where only the radiation scheme is subject to the increasing CO2, the temperature increase is close to that of the standard 1pctCO2 case.

Concentration-driven idealised simulations: carbon fluxes
The figure shows the globally integrated carbon source (positive) or sink (negative) to the atmosphere from the land (thin lines) and ocean (thick lines). A 10-year running-mean is shown as the land fluxes have large interannual variability responding to interannual climate variability.
The control simulation (black) shows carbon fluxes that are close to zero as required. Land carbon fluxes are more variable than ocean carbon fluxes. When atmospheric CO2 is instantaneously quadrupled, both land and ocean take up carbon (red) with the ocean sink being stronger and lasting longer than the land sink. When CO2 is increased by 1% per year, both land and ocean initially respond by taking up carbon (blue) but the land sink reduces over time and becomes a source as temperature increases. The behaviour is similar when only the biogeochemistry is forced with the increasing CO2 (green) with both ocean and land showing slightly larger CO2 sinks. When only the radiation scheme is forced with increasing CO2 (magenta), the ocean carbon flux remains close to zero while the land shows a carbon source, driven by the temperature increase in this case.
