mom_tracer_diabatic subroutine, public subroutine, public mom_tracer_diabatic::tracer_vertdiff (h_old, ea, eb, dt, tr, G, GV, sfc_flux, btm_flux, btm_reservoir, sink_rate, convert_flux_in) tracer_vertdiff h_old h_old ea ea eb eb dt dt tr tr G G GV GV sfc_flux sfc_flux btm_flux btm_flux btm_reservoir btm_reservoir sink_rate sink_rate convert_flux_in convert_flux_in This subroutine solves a tridiagonal equation for the final tracer concentrations after the dual-entrainments, and possibly sinking or surface and bottom sources, are applied. The sinking is implemented with an fully implicit upwind advection scheme. Alternate time units can be used for the timestep, surface and bottom fluxes and sink_rate provided they are all consistent. g ocean grid structure gv ocean vertical grid structure h_old layer thickness before entrainment [H ~> m or kg m-2] ea amount of fluid entrained from the layer above [H ~> m or kg m-2] eb amount of fluid entrained from the layer below [H ~> m or kg m-2] tr tracer concentration in concentration units [CU] dt amount of time covered by this call [T ~> s] sfc_flux surface flux of the tracer in units of [CU kg m-2 T-1 ~> CU kg m-2 s-1] or [CU H ~> CU m or CU kg m-2] if convert_flux_in is .false. btm_flux The (negative upward) bottom flux of the tracer in [CU kg m-2 T-1 ~> CU kg m-2 s-1] or [CU H ~> CU m or CU kg m-2] if btm_reservoir amount of tracer in a bottom reservoir [CU kg m-2]; formerly [CU m] sink_rate rate at which the tracer sinks [m T-1 ~> m s-1] convert_flux_in True if the specified sfc_flux needs to be integrated in time mom_error_handler::mom_error advection_test_tracer::advection_test_tracer_column_physics boundary_impulse_tracer::boundary_impulse_tracer_column_physics mom_diabatic_driver::diabatic_ale mom_diabatic_driver::diabatic_ale_legacy dome_tracer::dome_tracer_column_physics regional_dyes::dye_tracer_column_physics dyed_obc_tracer::dyed_obc_tracer_column_physics ideal_age_example::ideal_age_tracer_column_physics isomip_tracer::isomip_tracer_column_physics mom_diabatic_driver::layered_diabatic mom_ocmip2_cfc::ocmip2_cfc_column_physics oil_tracer::oil_tracer_column_physics pseudo_salt_tracer::pseudo_salt_tracer_column_physics rgc_tracer::rgc_tracer_column_physics subroutine, public subroutine, public mom_tracer_diabatic::applytracerboundaryfluxesinout (G, GV, Tr, dt, fluxes, h, evap_CFL_limit, minimum_forcing_depth, in_flux_optional, out_flux_optional, update_h_opt) applytracerboundaryfluxesinout G G GV GV Tr Tr dt dt fluxes fluxes h h evap_CFL_limit evap_CFL_limit minimum_forcing_depth minimum_forcing_depth in_flux_optional in_flux_optional out_flux_optional out_flux_optional update_h_opt update_h_opt This routine is modeled after applyBoundaryFluxesInOut in MOM_diabatic_aux.F90 NOTE: Please note that in this routine sfc_flux gets set to zero to ensure that the surface flux of the tracer does not get applied again during a subsequent call to tracer_vertdif. g Grid structure gv ocean vertical grid structure tr Tracer concentration on T-cell dt Time-step over which forcing is applied [T ~> s] fluxes Surface fluxes container h Layer thickness [H ~> m or kg m-2] evap_cfl_limit Limit on the fraction of the water that can be fluxed out of the top layer in a timestep [nondim] minimum_forcing_depth The smallest depth over which fluxes can be applied [H ~> m or kg m-2] in_flux_optional The total time-integrated amount of tracer that enters with freshwater out_flux_optional The total time-integrated amount of tracer that leaves with freshwater update_h_opt Optional flag to determine whether h should be updated mom_error_handler::mom_error advection_test_tracer::advection_test_tracer_column_physics boundary_impulse_tracer::boundary_impulse_tracer_column_physics dome_tracer::dome_tracer_column_physics regional_dyes::dye_tracer_column_physics dyed_obc_tracer::dyed_obc_tracer_column_physics ideal_age_example::ideal_age_tracer_column_physics isomip_tracer::isomip_tracer_column_physics mom_generic_tracer::mom_generic_tracer_column_physics mom_ocmip2_cfc::ocmip2_cfc_column_physics mom_offline_main::offline_fw_fluxes_into_ocean mom_offline_main::offline_fw_fluxes_out_ocean oil_tracer::oil_tracer_column_physics pseudo_salt_tracer::pseudo_salt_tracer_column_physics rgc_tracer::rgc_tracer_column_physics This module contains routines that implement physical fluxes of tracers (e.g. due to surface fluxes or mixing).
