-Depending on the complexity of the model used the vegetation will be either \\
-- computed by the model \\
-- prescribed to PI \\
-- prescribed to 6ka vegetation reconstructed from a combination of model output and data analyses (please use the map provided here)

+Please use the [[index#page_bottom_tag|discussion]] panel to **comment** this table!
-The simlations are force by the CO2 concentrations. Please use the same protocal as in CMIP5 to store the carbone fluxes and the variables needed for PCMIP (see list here)
-** Insolation **
-Note that insolation should follows PMIP requirements. Please check it carefuly using the following tables
+==== Vegetation ====
+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
-===== Initial conditions =====
+  * prescribed to PI (which means both vegetation types and LAI are prescribed )
+  * Prescribed to PI with interactive LAI (models with interactive carbone cycle, but no vegetation dynamics)
+  * Computed by the model (models with dynamic vegetation)
-^  ^ PMIP3 ^ Alternative solution ^
+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).
