Arguments:

• title — run's title
• netcdf_file — netCDF output file (rund ID)
• mode — calculation mode. Description:
  • 2 — 2-D calculation (bottom stress calculated in advave)
  • 3 — 3-D calculation (bottom stress calculated in profu,v)
  • 4 — 3-D calculation with t and s held fixed
• nadv — advection scheme. Options:
  • 1 — Centred scheme, as originally provide in POM
  • 2 — Smolarkiewicz iterative upstream scheme, based on subroutines provided by Gianmaia Sannino and Vincenzo Artale

Constants for Smolarkiewicz iterative upstream scheme:

• nitera — number of iterations. This should be in the range 1 - 4. 1 is standard upstream differencing; 3 adds 50% CPU time to POM
• sw — smoothing parameter. This should preferably be 1, but 0 < sw < 1 gives smoother solutions with less overshoot when nitera > 1
• npg — pressure gradient scheme. Options:
  • 1 — Second order scheme, as originally provide in POM
  • 2 — Fourth order scheme using the McCalpin method (Berntsen and Oey, Ocean Dynamics, 2010)
• dte — external (2-D) time step (secs.) according to CFL
• isplit — Ratio: (Internal (3-D) time step)/(External (2-D) time step) (dti/dte; dimensionless)
• time_start — date and time of start of initial run of model in format (i.e. UDUNITS convention) "YYYY-MM-DD HH:MM:SS <+/->HH:MM" where "<+/->HH:MM" is the time zone (positive eastwards from Coordinated Universal Time). NOTE that the climatological time axis (i.e. beginning of year zero, which does not exist in the real-world calendar) is used

Restart options:

• nread_rst — index to indicate whether run to start from restart file (nread_rst=0: no restart input file; nread_rst=1: restart input file)
• read_rst_file — restart input file name
• write_rst — interval (days) to write a restart file
• write_rst_file — restart output file name

Additional options:

• days — run duration (days)
• prtd1 — initial print interval (days)
• prtd2 — final print interval (days)
• swtch — time to switch from prtd1 to prtd2
• nbct — surface temperature boundary condition (see initialize.f)
• ifplane — f-plane option. Valid values:
  • 0 — Grid is not an f-plane, as originally provided in POM
  • 1 — Grid is an f-plane, calculated at latitude cnorth_e
• cnorth_e — Constant for f-plane option: latitude for Coriolis calculation when using an f-plane
• ismoth — smoothing/desmoothing option
  • 0 — do not use 3D U V T S smoothing
  • 1 — use 3D U V T S smoothing
• smh — Constant for smoothing/desmoothing option: smoothing time step frequency. This has traditionally been 3.
• tnowindd — no prescribed wind after tnowindd (days)
• igeovel — initial geostrophic velocity option. Valid values:
  • 0 — No calculation of initial geostrophic velocity
  • 1 — Calculate initial geostrophic velocity
• nl — number of z-levels in initial condition file(s)
• ionedim — 3D (full) vs. 1D (vertical-only) physics option. Valid values:
  • 0 — use full 3D physics
  • 1 — use vertical-only 1D phsyics
• ipwave — wave-induced mixing option
  • 0 — do not use wave-induced mixing
  • 1 — use wave-induced mixing
