Exclusion Experiments: Can we devise a series of physics exclusion experiments to help pinpoint relevant problems to polar bias and skill?

Exclusion experiments test the response of the system to changes in inputs. Examples include:

A. Starting from a spun up state, and then: 1) turning off all fluxes  in individual components (flywheel isolation),  2) turning off the sun (system spin down),   3) turning off individual incoming fluxes for the ocean, sea ice, land etc (component spin down).

B. Starting from rest: 1) Running the whole model without solar input (system stay-at-rest), 2) Running with all component fluxes turned off (component stay-at-rest type 1), 3) Running individual components with no flux input (component stay-at-rest type 2).
