| - | - computed by the model \\ | + | * prescribed to PI (which means both vegetation types and LAI are prescribed ) |
| - | - prescribed to PI (some ESM may only compute vegetation phenology and carbon cycle)\\ | + | * Prescribed to PI with interactive LAI (models with interactive carbone cycle, but no vegetation dynamics) |
| - | - prescribed to 6ka vegetation reconstructed from a combination of model output and data analyses (please use the map provided here) \\ | + | * Computed by the model (models with dynamic vegetation) |
| - | - Obtained from asynschonous coupling with a DVGM (Biome 4 model provided) | + | |
| + | 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). | ||
