     => one test simulation could be launched in force mode, setting the grasslands as evergreen 
   * The new diagnostic for looking at seasonal variation of LAI per PFT over specific regions developed by Vlad is not ready yet.
-  * Instead, we looked at the LAI maps generated per season (DJF,MAM,JJA,...) which are available on the mapper. We have seen that the LAI of PFT 10 for the coupled simulation with CN version and CN fix compares relatively well to the one from the coupled simulation with the standard ORCHIDEE. In contrast, the LAI from the simulation in force mode with CN version and CNdyn is much lower than the one with the ORCHIDEE standard. This may indicate that the problem in the phenology of grasslands is not strictly speaking a phenology problem but a problem of N availability which indirectly impacts on the LAI development.[[BR]]

   => We could run a new simulation with CN version and CN fix in force mode, in order to compare it with the simulation with CN dyn and also with the gimms product.[[BR]]
