This datasets contains netcdf output files of the simulations analyzed in Colin et al. "Groundwater feedbacks on climate change in the CNRM global climate model" submitted to Journal of Climate. 1. Monthly and daily outputs file names Monthly outputs : SimulationName_arpsfx_monthly_VariableName_year1-year2.nc Daily outputs : SimulationName_arpsfx_daily_VariableName_year1-year2_JJAS.nc Note : the daily outpus are available only for the "extended boreal summer" months, i.e. June, July, August, September 2. Simulation names PIC_FLD_632_NCB : named PIr in the paper, without groundwater, under Pre-industrial conditions, run over the 1850-1939 (year1-year2) period. PIC_GWFLD_632_NCB_clean : named PIa in the paper, with groundwater, under Pre-industrial conditions, run over the 1880-1969 (year1-year2) period. 4xCO2_FLD_632_NCB : named C4r in the paper, without groundwater, under 4xCO2 conditions (after stabilization), run over the 1850-1939 (year1-year2) period. 4xCO2_GWFLD_632_NCB_clean : named C4a in the paper, with groundwater, under 4xCO2 conditions (after stabilization), run over the 1880-1969 (year1-year2) period. Note : The years' numbering does not matter as it does not correspond to actual years. Each simulation was run for 90 years (after the spin-up procedures) in a stabilized climate under pre-industrial and 4xCO2 conditions. 3. Variable names et : evapotranspiration inflitr : liquid water inflitration in the soil lai : Leaf Area Index pr : precipitation rzwc : root zone water content tas_max : maximum daily 2-meter air temperature tas_min : minimum daily 2-meter air temperature tran : plants transpiration vegstress : Soil Wetness Index computed with a weighting of soil water content with root density along vertical layers wg : liquid soil water content in each vertical layers (sdepth) wtd : water table depth Note : wtd is defined on the river routing model (CTRIP) grid, at 0.5° resolution. All the other variables are defined on the grid common to the atmospheric model (Arpege-Climat) and land surface model (ISBA), at ~1° resolution. The variables units and any further needed informations are included in files metadata. 4. Other files (fixed fields) areacella.nc : grid cell areas of the ISBA/Arpege-Climat grid (Land Surface model and atmospheric model), areacellr.nc : grid cell areas of the CTRIP grid (River Routing model), land_area_fraction.nc : fraction of land surface in each cell of the the ISBA/Arpege-Climat grid, groundwater_mask.nc : groundwater mask, defined on the CTRIP grid, groundwater_mask_on_Isba-Arpege_grid.nc : groundwater mask interpolated onto the ISBA/Arpege-Climat grid (using the "remapcon" function of CDO), root_depth.nc : root depth, defined on the ISBA/Arpege-Climat grid, root_depth_on_CTrip_grid.nc : root depth interpolated onto the CTRIP grid (using the "remapcon" function of CDO).
