icon_sc.icon.names — the ICON variable registry¶

ICON variable-registry seed (architecture §2.5, S06).

One literal table maps each canonical name to canonical units, CF standard name (where CF has one), ICON Fortran short name, and (later, for ingestion only) the GRIB2 triplet. Naming follows §2.5 as enforced by icon_sc.core.state.names: CF standard names are canonical and unprefixed; solver-internal quantities live in the icon: namespace.

Provenance (REFERENCES.lock, S06):

prognostics/tracers/diagnostics: icon4py v0.2.0 states/data.py short names (rho/w/theta_v/exner/vn/…) — the first 18 rows were seeded by S02 in icon_sc.core.state.names and are re-asserted (not re-registered) here;
interface-level fields pres_ifc/temp_ifc and the tendency-bus slots ddt_exner_phy (ICON t_nh_diag, mo_nonhydro_types.f90) and the ddt_temp*/ddt_q* family (ICON prm_nwp_tend naming, mo_nwp_phy_types.f90);
metric/reference-state fields z_mc/z_ifc/ddqz_z_full/ddqz_z_half/ *_ref_mc (ICON t_nh_metrics; icon4py metric_fields/ reference_atmosphere).

Unit-string discipline: Exner is "1" (PLAN pitfall — never “dimensionless”); tracer mass fractions are "1", their tendencies "s-1".

Importing this module seeds the registry (idempotently: rows already registered by icon_sc.core are verified for consistency instead). QUANTITIES (frozen interface) is the full table, insertion-ordered.
