5.4.1. Namelist NAM_PREP_WATFLUX

This namelist information is used to initialize the "WATFLX" sea scheme temperature.

LWAT_SBL logical F

  • XTS_WATER_UNIF : uniform prescribed value of water surface 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_WATFLX data.
  • CFILE_WATFLX / CFILEPGD_WATFLX: name of the PREP / PGD files used to define the Sea surface Temperature. The use of a file or prescribed value XTS_WATER_UNIF has priority on the data in CFILE_WATFLX file.
  • CTYPE / CTYPEPGD: type of the CFILE_WATFLX / CFILEPGD_WATFLX file, if the latter is provided. CTYPE / CTYPEPGD 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).
  • LWAT_SBL : activates surface boundary multi layer scheme over inland water.
