ocean_ice_ic_config_t Derived Type

type, public :: ocean_ice_ic_config_t

&ocean_ice_ic_nml: sea-ice ANALYTIC initial-condition path (PR 24). Default conc_config="zero" early-returns before touching a single ice array => byte-identical to today for every existing nml/test. v1 ships "uniform" (scalar) and "latitudes" (SIS2 polar-cap analytic form) only — file-backed ICs are deliberately NOT in the allowed list ("file" is v1.1, PR-14).

Components

Type Visibility Attributes Name Initial
real(kind=wp), public :: antarctic_edge = -91.0_wp

"latitudes" Antarctic ice edge (degrees_north) — SIS2 ANTARCTIC_ICE_EDGE_IC default (no cell qualifies => no ice).
real(kind=wp), public :: arctic_edge = 91.0_wp

"latitudes" Arctic ice edge (degrees_north) — SIS2 ARCTIC_ICE_EDGE_IC default (no cell qualifies => no ice).
real(kind=wp), public :: conc = 0.0_wp

Uniform-mode concentration [0,1] (nondim). "uniform" only.
character(len=32), public :: conc_config = "zero"

"zero" (default, no-op) / "uniform" / "latitudes".
real(kind=wp), public :: h_ice = 0.0_wp

Ice thickness (m) where seeded — SIS2 ICE_INIT_MASS as a thickness.
real(kind=wp), public :: h_snow = 0.0_wp

Snow thickness (m) where seeded — SIS2 SNOW_INIT_MASS as a thickness. Snow is a one-way street (no snowfall source anywhere in the tree) — this can only ever melt.
real(kind=wp), public :: s_ice = 4.0_wp

Ice bulk salinity (PSU) — SIS2 ICE_SALINITY_IC default, matching ICE_BULK_SALINITY (ocean_sea_ice_init’s own sal_ice source value).
real(kind=wp), public :: t_ice = -4.0_wp

Ice/snow temperature (degC) fed through the exact ice_enth_from_ts inversion — SIS2 ICE_TEMPERATURE_IC default.
