esm-flat10
Warning
The ACCESS-ESM1.6 esm-flat10 experiment does not have a released and maintained configuration. These notes describe how the CMIP7 experiment was set up and are for reference only. If you would like to run an esm-flat10 experiment with the latest configuration updates, please create a help request on the ACCESS Hive Forum.
The esm-flat10 experiment simulates the climate under constant anthropogenic emissions of 10PgC/year using a fully interactive carbon cycle, with preindustrial values used for all other atmospheric forcings. This experiment is run for the CMIP7 esm-flat10 experiment.
The experimental setup matches commit 2dc195a from the esm-piControl configuration with changes for prescribing the flat CO2 emissions and the restart file used.
Inputs¶
The esm-flat10 experiment uses the same input files as the esm-piControl configuration, with changes for specifying CO2 emissions and a different initial condition.
Atmosphere:¶
The following file is used to provide the constant CO2 emissions to the atmosphere model:
- CO2_fluxes_flat10.anc: Constant gridded CO2 emissions in units kg(CO2) m-2 s-1, totalling 10Pg(C) year-1.
Restart¶
The esm-flat10 experiment uses the restart from the esm-piControl experiment with calendar year 201.
Key settings¶
The following settings are used to read the CO2 emissions from the input file. Differences are shown with respect to the esm-piControl configuration:
