| - | 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). | + | A 6ka reconstructed vegetation map from a combination of model outputs and data analyses will be provided for sensitivity experiments. If you are interested please contact Bette Otto-Bliesner, Sandy Harrison and Pat Bartlein who will lead the corresponding working group. |
