    2727In addition to the Nitrogen-related forcings, the mineral nitrogen dynamic model needs soil pH and soil bulk density which are provided as model inputs. Default bulk density at 0.5×0.5 degree resolution is from the Harmonized World Soil Database (HWSD; FAO/IIASA/ISRIC/ISSCAS/JRC, 2012) and default soil pH from the International Geosphere–Biosphere Programme Data Information System (Global Soil Data Task Group, 2000). Datasets are stored on the shared repositories here: ${R_IN}/SRF/SOIL/soil_bulk_and_ph.nc

    3030An alternative configuration has been developped without carbon-nitrogen interactions, which can be used for studies/simulations not focusing on nitrogen impact or for control simulations and sensitiviy studies as it has been done in Vuichard et al., 2019. This configuration is the default setting for CL4 or CL5 simulations with ORCHIDEE_3 (see http://forge.ipsl.jussieu.fr/igcmg/svn/CONFIG/UNIFORM/v6/LMDZOR_v6.3/). This configuration is activated when the flag IMPOSE_CN is set to ''true''. In that case, the C/N ratio is fixed per PFT for all pixels. In combination to the flag IMPOSE_CN, if the flage STOMATE_READ_CN is set to ''true'', the C/N ratio is read per PFT from 2D map. The default 2D map used in this case is stored under ${R_IN}/SRF/NITROGEN/CN_LEAF/cn_leaf_1850_v0.nc
