  • "ASCII / LFI ": PREP file from Surfex
  • "ASCLLV": ASCII latlonval file (one file for each depth)
  • "NETCDF": netcdf standard file (one variable by depth)
• XTG_SURF : uniform prescribed value of temperature for the surface soil layer, supposed at an altitude of 0m (mean sea level altitude). The temperature is then modified for each point depending on its altitude, following a uniform vertical gradient of -6.5 K km^-1. This prescribed value, if defined, has priority on the use of CFILE_TG and CFILE_ISBA data.
• XTG_ROOT : uniform prescribed value of temperature for the root zone soil layer(s), supposed at an altitude of 0m (mean sea level altitude). The temperature is then modified for each point depending on its altitude, following a uniform vertical gradient of -6.5 K km^-1. This prescribed value, if defined, has priority on the use of CFILE_TG and CFILE_ISBA data.
• XTG_DEEP : uniform prescribed value of temperature for the deep soil layer(s), supposed at an altitude of 0m (mean sea level altitude). The temperature is then modified for each point depending on its altitude, following a uniform vertical gradient of -6.5 K km^-1. This prescribed value, if defined, has priority on the use of CFILE_TG and CFILE_ISBA data.
• CFILE_TG_SURF: name of the file used to define the surface soil temperature profile.
• CFILE_TG_ROOT: name of the file used to define the root zone soil temperature profile.
• CFILE_TG_DEEP: name of the file used to define the deep soil temperature profile.
• CFILE_TG: name of the file used to define the soil temperature profile.
  The use of a file or prescribed value of XTG_SURF, XTG_ROOT and XTG_DEEP has priority on the data in CFILE_TG file.
