    2020=== Land cover change map === 
    21  
     21Each project will have to prepare its own land cover change maps based on the number of PFTs and the time frame of the simulations, i.e., historical or future. 
    2222 
    2323=== Climate forcing === 
     24In the short term the configuration will make use of the SAFRAN forcing. In the future higher resolution forcing produced by ORCHIDEE-WRF could become available. 
    2425 
    2526=== Soil map === 
     27INRAE soil map will be used. See discussion 
    2628 
    2729=== Management === 
     30Each project will have to prepare its own management maps based on the number of PFTs and the objectives of the study. 
    2831 
    2932=== River basins === 
    30 Not working yet at this resolution. For the time being we could store high resolution run-off information through the history files. Run-off could be calculated in post-processing.

    110 Configuration simulation experiments 
    111 ORCHIDEE 2.x (3.x foreseen in a second step with Nicolas Vuichard): sechiba, stomate with HR routing, GWF, and irrigation 
    112 Restart:  from spinup  
    113 PFT map: first step with CMIP6 maps, and attempts to use French agricultural census 
    114 Land cover change: yes, using standard CMIP6 maps 
    115 Climate forcing: SAFRAN (~ 8x8 km) + downscaled bias-corrected climate projections from other partners of the projects ; CORDEX output

    120 3. Projects: Carbon flux simulation in the context of the VERIFY project and in collaboration with CITEPA  
    121 Matthew Mcgrath, Philippe Peylin, …. 
    122  
    123 We started a discussion with CITEPA which is an agency making the Greenhouse gaz budget for France for the UNFCCC. They are considering of “possibly” using the ORCHIDEE model as an additional source of information for their budget (the NBP of ORC) 
    124  
    125 We should probably phase these simulations with Project-1 of Guillaume Marie. 
    126  
    127 But CITEPA could contribute as they have “made” specific land cover maps for France (annual) based on different products (ESA-CCI, a map from CESBIO, Corinne LC, ..) 
    128  
    129 4. Produce adequate forcing to run ORCHIDEE at km-scales 
    130 Jan Polcher, Nicolas Vuichard, Nathalie De Noblet, …  
    131 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.

    138 Dear Sebastiann, 
    139  
    140 that is fine with me. 
    141  
    142 You have to know that there is a project which will be submitted next 
    143 week to build a forcing for ORCHIDEE at 3km. This would mean running 
    144 RegIPSL (WRF+ORCHIDEE) forced with ERA5. It would provide a dynamically 
    145 downscaled version of the re-analysis which can serve for model 
    146 development ... and in the end see how these improvements feedback o the 
     48* Land cover change map: to be created based on the NFI age distribution map, NFI species distribution map, and the LUHv2 or another LCC product.  
     49* Climate forcing: medium resolution (~ 8x8 km) no other specific requirements. Currently looking into SAFRAN data 1986 to 2018. 
     50* Soil map: if available the soil map from a previous ADEME project. If not any soil map could do. 
     51* Forest management map: for a recent year (default or based on NFI) 
     52 
     53=== Configuration transient === 
     54Included 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.
