 + 
 +==== Vegetation ==== 
 + 
 +Depending on the complexity of the model used the vegetation will be either 
 + 
 +  * computed by the model 
 +  * prescribed to PI (some ESM may only compute vegetation phenology and carbon cycle) 
 +  * prescribed to 6ka 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)  
 + 
 + 
 +==== For Earth System Models with interactive carbone cycle ==== 
 + 
 +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)  
 + 
 +==== Insolation ==== 
 + 
 +Note that insolation should follows PMIP requirements. Please check it carefully using the following tables ([[http://​pmip2.lsce.ipsl.fr/​design/​tables/​inso_tables_6k.shtml|6ka BP insolation tables]])
