Model output from the Weather Research and Forecasting model, WRF and the Community Terrestrial Systems Model, CTSM (corresponds to the Community Land Model Version 5, CLM5) over the domain of Nordic Fennoscandia (Norway, Sweden and Finland) at 10.5 km x 10.5 km horizontal resolution using initial and boundary conditions from ERA5. All files contain SM_SURF (mean daily surface soil moisture in the 0-0.1 m soil depth layer), T2MAX (maximum daily 2 m temperature), P (daily accumulated convective and non-convective cumulus and grid scale precipitation), SH (mean daily surface sensible heat flux), LH (mean daily surface latent heat flux), ET (mean daily evaporation), QSOIL (mean daily ground evaporation), QVEGE (mean daily canopy evaporation), QVEGT (mean daily canopy transpiration), EF (mean daily evaporative fraction), RNET (mean daily surface net radiation), SWIN (mean daily shortwave incoming radiation at the surface), SWOUT (mean daily shortwave outgoing radiation at the surface), LWIN (mean daily longwave incoming radiation at the surface) and LWOUT (mean daily longwave outgoing radiation at the surface) variables. Run_1.nc contains output from the WRF-CTSM 5.0 simulation for 13 years between 2010 and 2022 and uses the Ball-Berry stomatal conductance method, 4 soil moisture layers (up to 2 m depth) and no subgrid plant functional types (PFTs) heterogeneity. Run_2.nc contains output from the WRF-CTSM 5.1 simulation for the year 2018 and uses the Medlyn stomatal conductance method, 20 soil moisture layers (up to 8.6 m depth), and subgrid PFTs heterogeneity. Run_3.nc contains output from the WRF-CTSM 5.1 simulation for the year 2018 and uses the same settings as Run_2.nc, with the addition of the plant hydraulic stress (PHS) configuration. Run_4.nc contains output from the WRF-CTSM 5.1 simulation for the year 2018 and uses the same settings as Run_3.nc, with the addition of the biomass heat storage (BHS) configuration.
