+==== Ice-sheet ====
+The ice sheet to be used for PMIP3/CMIP5 experiments is still under discussion.

 ==== Vegetation ====
-Depending on the complexity of the model used the vegetation will be either:
+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
+  * 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)
-  * computed by the model
+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 panel).
-  * prescribed to PI (some ESM may only compute vegetation phenology and carbon cycle)
-  * prescribed to 21ka vegetation reconstructed from a combination of model output and data analyses (please use the map provided here)
-  * Obtained from asynchronous coupling with a DVGM ([[http://pmip2.lsce.ipsl.fr/synth/biome4.shtml|Biome 4 model]] provided)
