ice_ic_params_t Derived Type

type, public :: ice_ic_params_t

Sea-ice IC scalar knob bundle (mirrors ice_evp_params_t). Built ONCE from &ocean_ice_ic_nml via ice_ic_params_from_config; every field a plain scalar (no derived-type deref inside the host loop, same discipline as the EVP params — though this module never runs on-device at all).

Components

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

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

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

Uniform-mode concentration [0,1] (nondim).
integer, public :: conc_config = ICE_IC_CONC_ZERO

Parsed conc_config enum (ICE_IC_CONC_*).
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.
real(kind=wp), public :: s_ice = ICE_BULK_SALINITY

Ice bulk salinity (PSU) — SIS2 ICE_SALINITY_IC default, which matches ocean_sea_ice_init’s own sal_ice source value, so "uniform" at the default s_ice leaves sal_ice unchanged.
real(kind=wp), public :: t_ice = -4.0_wp

Ice/snow temperature (degC) — SIS2 ICE_TEMPERATURE_IC default.
