  • XSST_UNIF : uniform prescribed value of Sea Surface Temperature. This prescribed value, if defined, has priority on the use of CFILE_SEAFLX data.
  • CFILE_SEAFLX / CFILEPGD_SEAFLX: name of the PREP/PGD files used to define the Sea surface Temperature. The use of a file or prescribed value XSST_UNIF has priority on the data in CFILE_SEAFLX file.
  • CTYPE_SEAFLX / CTYPEPGD: type of the CFILE_SEAFLX / CFILEPGD_SEAFLX files, if the latter is provided. CTYPE_SEAFLX 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
    • "NETCDF" : the file type is a NETCDF file, coming from MERCATOR (possible only for CTYPE_SEAFLX)
    • "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).
  • LSEA_SBL : activates surface boundary multi layer scheme over sea.
  • LOCEAN_MERCATOR : oceanic variables initialized from MERCATOR if T
  • LOCEAN_CURRENT : initial ocean state with current (if F ucur=0, vcur=0)
  • XTIME_REL : time of relaxation (s)
  • LCUR_REL : flag for relaxation on current
  • LTS_REL : flag for relaxation on ocean temperature
  • LZERO_FLUX : flag for testing zero incoming flux at the ocean surface
  • LCORR_FLUX : flag for flux correction
  • XCORFLX : correction coefficient for surface fluxes
  • LDIAPYC : flag for diapycnal mixing activation
  • XSSS_UNIF : from V8, uniform prescribed value of Sea Surface Salinity. This prescribed value, if defined, has priority on the use of CFILE_SEAFLX data.
  • CSEAICE_SCHEME : from V8, name of the sea-ice scheme to activate. For details, see 6.2.4. Gelato sea-ice scheme
  • XSIC_UNIF: uniform sea ice covert fraction
