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
There are still questions concerning the possibility to have a 6ka reconstructed vegetation from a combination of model output and data analyses that could be used for sensitivity experiments. Please tell if you are interested by such a map and what would be the best variables (pft?) that should be provided (see comment from B. Otto-Bliesner in the discussion pannel).
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)
