Vegetation | prescribed or interactive as in CMIP5 PI |
Ice sheets | Same as PI * |
Topography and coastlines | Same as PI * |
* Sensitivity experiments will be proposed as part of a working group to test the uncertainties due to the remnant ice-sheet. If you are interested to participate to this working group contact Pascale Braconnot
The vegetation should be treated as in the CMIP5 PI experiment. The reason is that in CMIP5 we test the version of the model used for future climate projections. Since OA and ESM models will be considered, depending on the model used the vegetation will be
A 6ka reconstructed vegetation map from a combination of model outputs and data analyses will be provided for sensitivity experiments. If you are interested please contact Bette Otto-Bliesne, Sandy Harrison and Pat Bartlein who will lead the corresponding working group.
The simulations are forced by CO2 concentrations. Please use the same protocol as in CMIP5 to store the carbone fluxes and the variables needed for PCMIP (see list here)
Note that insolation should follows PMIP requirements. Please check it carefully using the following tables (6ka BP insolation tables)

Initial conditions | Branch off PI after adjustement | Same as in PI |
Model spin up | Same as in PI |
