Experiment Setup and Forcings Guidance: esm-flat10
10 PgC / yr constant carbon dioxide emissions.
- Responsible activity: C4MIP
- Tier: 1
- MIP co-chair review: In progress see https://github.com/WCRP-CMIP/cmip7-guidance/issues/186
This page is intended to help with implementation. If you notice something that is unclear, please raise an issue.

Experiment set up¶
Parent experiment and branching¶
The esm-flat10 experiment branches from the esm-piControl experiment (part of CMIP). The parent experiment's MIP era is CMIP7.
Branch from esm-piControl at a time of your choosing.
Output time axis¶
You are free to start and end the time axis of your outputs at whatever time you like (e.g. starting at year 1, or 1850, or year 500). You must perform at least 100 simulation years.
Minimum ensemble size¶
Only one ensemble member is required.
Forcings¶
The following information will help you identify the forcings to use. However, we can't define every single detail because there can be lots of subjective steps between the raw forcings data and model inputs (e.g. interpolation, re-aggregation, supplementation with other information). If further guidance would be helpful, please raise an issue.
General headlines¶
The esm-flat10 experiment is a fixed forcings experiment.
Data¶
Here we make a distinction between data that is described on other experiment pages, data that is described on other experiment pages with modifications you have to make yourself, data available via ESGF's input4MIPs project and data distributed via other channels.
Data described on other experiment pages¶
For the following data, please see these other experiment pages:
- piControl for biomass burning emissions, land use, greenhouse gas concentrations, stratospheric aerosol forcing, solar, aerosol optical properties, population density, ozone, nitrogen deposition
Data described on other experiment pages with modifications you have to make¶
For the following forcings, please use data from the specified experiments with the specified modifications.
- for anthropogenic emissions, use the forcings from piControl but set the total CO2 emissions to 10 PgC / yr
Data available via input4MIPs¶
No input4MIPs-based data is described specifically on this page. Please see the other data sub-sections for details of the forcings data to use for this experiment.
Data not available via input4MIPs¶
No data that is not input4MIPs-based is described specifically on this page. Please see the other data sub-sections for details of the forcings data to use for this experiment.
