Responsible activity: CMIP

In combination with piClim-control, quantifies a quadrupling of atmospheric carbon dioxide's (4xCO2's) effective radiative forcing (ERF). Same as piClim-control, except atmospheric carbon dioxide concentrations are set to four times piControl levels.

Experiment set up¶

The piClim-4xCO2 simulation uses the same forcings as piClim-control, except atmospheric CO₂ concentrations are set to four times the concentrations used in the piclim-control simulation.

It is recommended that you use the same time axis as you use for your piClim-control output to make life easy for analysts of your output (although this is not enforced so you are technically free to start the time axis of your outputs at whatever year you like). Simulations should be at least 30 years in length. Only one ensemble member is required.

Parent experiment¶

piClim-4xCO2 does not branch from another simulation.

Forcings¶

General headlines¶

Notes¶

See notes for the piClim-control simulation.

Versions to use¶

The forcings relevant for this simulation are the same as for the piClim-control simulation.

Getting the data¶

See instructions for the piClim-control simulation. You have to quadruple the atmospheric CO₂ concentrations yourself.
