5.7.5. Namelist NAM_PREP_TEB_GREENROOF

This namelist information is used to initialize the "GREENROOF" vegetation scheme variables: soil temperature profile, soil water and ice profiles, water intercepted by leaves, snow.

• XHUG_SURF_GR : uniform prescribed value of liquid soil water index (SWI) for the surface soil layer. This prescribed value, if defined, has priority on the use of CFILE_HUG_GR and CFILE_GR data.
• XHUG_ROOT_GR: uniform prescribed value of liquid soil water index (SWI) for the root zone soil layer(s). This prescribed value, if defined, has priority on the use of CFILE_HUG_GR and CFILE_GR data.
• XHUG_DEEP_GR : uniform prescribed value of liquid soil water index (SWI) for the deep soil layer(s). This prescribed value, if defined, has priority on the use of CFILE_HUG_GR and CFILE_GR data.
• XHUGI_SURF_GR : uniform prescribed value of ice soil water index (SWI) for the surface soil layer. This prescribed value, if defined, has priority on the use of CFILE_HUG_GR and CFILE_GR data.
• XHUGI_ROOT_GR :uniform prescribed value of ice soil water index (SWI) for the root zone soil layer(s). This prescribed value, if defined, has priority on the use of CFILE_HUG_GR and CFILE_GR data.
• XHUGI_DEEP_GR : uniform prescribed value of ice soil water index (SWI) for the deep soil layer(s). This prescribed value, if defined, has priority on the use of CFILE_HUG_GR and CFILE_GR data.
• CFILE_HUG_SURF_GR: name of the file used to define the liquid soil water index (SWI) for the surface soil layer.

• CFILE_HUG_DEEP_GR: name of the file used to define the liquid soil water index (SWI) for the deep soil layer(s).
• CFILE_HUG_GR: name of the file used to define the soil water profiles.
  The use of a file or prescribed value of XHUG_SURF, XHUG_ROOT_GR and XHUG_DEEP_GR has priority on the data in CFILE_HUG_GR file.
• CTYPE_HUG: type of the CFILE_HUG_GR file, if the latter is provided. CTYPE_HUG must then be given. The following values are currently usable:

    4. "MOCAGE" : Mocage french research chemistry model
  • "ASCII / LFI ": PREP file from Surfex
  • "ASCLLV": ASCII latlonval file (one file for each depth)
• XTG_SURF_GR : 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_GR and CFILE_GR data.
• XTG_ROOT_GR : 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_GR and CFILE_GR data.
• XTG_DEEP_GR : 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_GR and CFILE_GR data.
• CFILE_TG_SURF_GR: name of the file used to define the surface soil temperature profile.
• CFILE_TG_ROOT_GR: name of the file used to define the root zone soil temperature profile.
• CFILE_TG_DEEP_GR: name of the file used to define the deep soil temperature profile.
• CFILE_TG_GR: name of the file used to define the soil temperature profile.
  The use of a file or prescribed value of XTG_SURF_GR, XTG_ROOT_GR and XTG_DEEP_GR has priority on the data in CFILE_TG_GR file.
• CTYPE_TG: type of the CFILE_TG_GR file, if the latter is provided. CTYPE_TG must then be given. The following values are currently usable:
