Experiment Setup and Forcings Guidance: esm-scen7-ml-ext

Extension of esm-scen7-ml beyond 2100.

This page is intended to help with implementation. If you notice something that is unclear, please raise an issue.

Paired experiments

  • scen7-ml-ext is the concentration-driven counterpart to this emissions-driven experiment.

Experiment set up

Parent experiment and branching

The esm-scen7-ml-ext experiment branches from the esm-scen7-ml experiment (part of ScenarioMIP). The parent experiment's MIP era is CMIP7.

Branch from esm-scen7-ml at 2100-12-31.

Output time axis

Your output time axis must start on 2101-01-01 and must not end later than 2500-12-31. You must perform at least 50 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-scen7-ml-ext experiment uses a mix of fixed and transient forcings. The fixed forcings are: nitrogen deposition, ozone and stratospheric aerosol forcing. The transient forcings are: aerosol optical properties, anthropogenic emissions, biomass burning emissions, greenhouse gas concentrations, land use, population density and solar.

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

All data is described on the scen7-ml-ext experiment page.

Data described on other experiment pages with modifications you have to make

No data described on other experiment pages requires modifications by you. Please see the other data sub-sections for details of the forcings data to use for this experiment.

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.
