 Use the namelist [namelist_soilera5_cmip6_pgw.wps](namelist_soilera5_cmip6_pgw.wps) where we need to adapt the dates depending on the dates of the soil_clim_dec.grb, which will depend on the files we used to generate the mean.

 This will generate a file SOILERA5:2005-12-01_00 (this will be the date if your first file in the climatology is for 01/12/2005). This file can be used as a constant.

 There is a module in real/wrf  that should be changed too [module_initialize_real.F](module_initialize_real.F)->[module_initialize_real.F_modified](module_initialize_real.F_modified), so that the model only uses soil variables for initialization and ignores the rest (not sure this is entirely necessary, but it is if only the first step is provided.)
