PUBLIC ROUTINES

  1. ocean_parameters_init

    DESCRIPTION
    Initialize the parameter module, passing cp_ocean back to ocean_model.F90 and setting all other parameters that will be used throughout the model simulation. Note: we do not enable check_nml_error, since the default settings are generally those recommended for simulations.


  2. ocean_parameters_end

    DESCRIPTION
    Summarize the basic physical parameters used in the simulation.

&ocean_parameters_nml

cp_ocean
Specific heat capacity J/(kg degC) for liquid seawater. Values are taken from from Jackett etal (2006) for preTEOS10 and from TEOS-10 manual for TEOS10 value. The default values differ from that in shared/constants since the MOM defaults are more updated. Note that there is a check inside of ocean_tempsalt.F90 to ensure that cp_ocean=cp_ocean_teos10 if using the teos10 recommendations, and cp_ocean=cp_ocean_preteos10 for cases not using teos10.
[real, units: J/(kg degC)]
cp_solid_runoff
Specific heat capacity J/(kg degC) for solid water runoff via calving land ice. Default cp_solid_runoff = 2106.0 is consistent with that used in the GFDL land model.
[real, units: J/(kg degC)]
cp_liquid_runoff
Specific heat capacity J/(kg degC) for liquid water runoff from land. Default cp_liquid_runoff = 4218.0 is consistent with that used in the GFDL land model.
[real, units: J/(kg degC)]
rho0
Boussinesq reference density. Default rho0=1035.0 corresponds to the value in Gill (page 47), where he notes that the ocean density typically deviates less than 2 per cent from this value. But if using the Boussinesq approximation for other water bodies, such as the Baltic, then may wish to change rho0 to a more appropriate value.
[real, units: kg/m^3]
tfreeze
freezing point of fresh water at standard atmos pressure. Default tfreeze=273.15
[real, units: Kelvin]
omega_earth
rotation of earth in radians per second Default omega_earth= 7.2921e-5, as per equation (4.1) in Griffies (2004).
[real, units: radians per second]
grav
Gravitational acceleration at earth surface. Assumed to be constant throughout the ocean domain. Default grav=9.8 corresponds to the "grav" parameter from shared/constants.F90.
[real, units: m/s^2]
von_karman
Von Karman constant for law of wall turbulence. Default von_karman=0.4. Note: due to answer changes on some compilers, von_karman has been removed from nml and is now set as a hard-value to be consistent with earlier simulations (06mar2012).
[real, units: dimensionless]
