5.7.1. Namelist NAM_PREP_TEB

This namelist information is used to initialize the "TEB " urban scheme variables: road, roof and wall temperature profiles, water intercepted by roofs and roads, snow, building internal temperature.

• XWS_ROAD : uniform prescribed value of soil water interception for the road reservoir. This prescribed value, if defined, has priority on the use of CFILE_WS and CFILE_TEB data.
• XWS_ROOF : uniform prescribed value of soil water interception for the roof reservoir. This prescribed value, if defined, has priority on the use of CFILE_WS and CFILE_TEB data.
• CFILE_WS: name of the file used to define the soil water reservoirs. The use of a file or prescribed value of XWS_ROAD and XWS_ROOF has priority on the data in CFILE_WS file.
• CTYPE_WS: type of the CFILE_WS file, if the latter is provided. CTYPE_WS must then be given. The following values are currently usable:
  • "MESONH" : the file type is a MESONH file.
  • "GRIB " : the file type is a GRIB file, coming from any of these models:
    1. "ECMWF " : european center forecast model
    2. "ARPEGE" : Arpege french forecast model
    3. "ALADIN" : Aladin french forecast local model
    4. "MOCAGE" : Mocage french research chemistry model
• XTS_ROAD : uniform prescribed value of temperature for road, 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_TS and CFILE_TEB data.
• XTS_ROOF : uniform prescribed value of temperature for roof, 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_TS and CFILE_TEB data.
• XTS_WALL : uniform prescribed value of temperature for wall, 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_TS and CFILE_TEB data.
• XTI_BLD : uniform prescribed value of internal building temperature. This temperature is not dependent on altitude. This prescribed value, if defined, has priority on the use of CFILE_TS and CFILE_TEB data.
• XTI_ROAD : uniform prescribed value of deep road temperature, 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_TS and CFILE_TEB data.
• XHUI_BLD : uniform bulding relative hum (between 0-1)
• CROAD_DIR : TEB option for road direction:
  • UNIF : no specific direction
  • ORIE : many road ORIEntations (linked to NTEB_PATCH)
• CWALL_OPT : TEB option for walls:
  • UNIF : uniform walls
  • TWO : two separated walls
• CFILE_TS: name of the file used to define the soil temperature profile. The use of a file or prescribed value of XTS_ROAD, XTS_ROOF, XTS_WALL, XTI_BLD or XTI_ROAD has priority on the data in CFILE_TS file.
• CTYPE_TS: type of the CFILE_TS file, if the latter is provided. CTYPE_TS must then be given. The following values are currently usable:
  • "MESONH" : the file type is a MESONH file.
  • "GRIB " : the file type is a GRIB file, coming from any of these models:
    1. "ECMWF " : european center forecast model
    2. "ARPEGE" : Arpege french forecast model
    3. "ALADIN" : Aladin french forecast local model
    4. "MOCAGE" : Mocage french research chemistry model
• CFILE_TEB / CFILEPGD_TEB: name of the PREP/PGD files used to define any TEB variable. The use of a file or prescribed value XWS_ROAD, XWS_ROOF, XTS_ROAD, XTS_ROOF, XTS_WALL, XTI_BLD, XTI_ROAD, CFILE_WS or CFILE_TS has priority on the data in CFILE_TEB file.
• CTYPE / CTYPEPGD: type of the CFILE_TEB / CFILEPGD_TEB file, if the latter is provided. CTYPE must then be given. The following values are currently usable:
  • "MESONH" : the file type is a MESONH file.
  • "GRIB " : the file type is a GRIB file, coming from any of these models:
    1. "ECMWF " : european center forecast model
    2. "ARPEGE" : Arpege french forecast model
    3. "ALADIN" : Aladin french forecast local model
    4. "MOCAGE" : Mocage french research chemistry model
  • "ASCII ": PREP/PGD Surfex ASCII file
  • "LFI ": PREP/PGD Surfex LFI file
• NYEAR : year of surface UTC time. It is used only if no atmospheric file or no surface file is given (in those the date can be read).
• NMONTH : month of surface UTC time. It is used only if no atmospheric file or no surface file is given (in those the date can be read).
• NDAY : day of surface UTC time. It is used only if no atmospheric file or no surface file is given (in those the date can be read).
• XTIME : time from midnight of surface UTC time. It is used only if no atmospheric file or no surface file is given (in those the date can be read). (seconds).
• LTEB_CANOPY : activates surface boundary multi layer scheme over town.
