    8585=== Configuration transient === 
    86 Included in the spinup thanks to a dedicated land cover change map. This method only works when we try to match the forest age in a recent year. A present day forest age map could be created based on the NFI data. With this information we know when the forest was planted. We can then look at the LUH maps to see whether the pixel was forest or not. If it was a forest we keep the same forest if it was a grassland or cropland we change it. This gives the land cover map than will be used for the spinup. Following the spinup a transient run will account for the LCC in the correct year. That method will result in the correct age distribution of the forest in France in a recent year.

    113113=== Produce forcing to run ORCHIDEE at km-scales ===

    115 * Short description: To be able to use ORCHIDEE over France at an appropriate resolution we also need the adequate forcing. Not only in terms of spatial resolution but also on the quality of the diurnal cycle of rainfall. I.e. the intensity of rainfall needs to be correct so that all the issues with ORCHIDEE’s water cycle come to light and we can explore our ability to simulate extreme events. This would mean running RegIPSL (WRF+ORCHIDEE) forced with ERA5. It would provide a dynamically downscaled version of the re-analysis which can serve for model development ... and in the end see how these improvements feedback to the 
    116 atmosphere.
