stilt.config.Variant#

class stilt.config.Variant(name: 'str', met: 'str', met_config: 'Any', transport: 'TransportConfig', model: 'ModelInfo', realizations: 'int | None' = None, footprint: 'FootprintConfig | None' = None, geometry_hash: 'str | None' = None) → None[source]#

One variant, resolved: its configs, its met, the model build, and its hashes.

Get one from project.variants or sim.variant. A variant with realizations: N is an ensemble: its simulations run N times, realization k with seed + k (transport_for()), and its results share one folder, a realization=k partition each.

Variants with equal particles_hash share one run of the transport model per receptor (and realization) and differ only in their footprints. The hashes are computed once. Change a variant with dataclasses.replace(), which computes them again.

Attributes#

`footprint_hash`	Hash of the particles and `footprint_settings`, which finds the footprint folder.
`footprint_settings`	The settings that identify this variant's footprints, or `None` for particles only.
`met_settings`	What a run records of the met, its config's `settings()`.
`particles_hash`	Hash of `run_settings`, which finds the particles folder.
`realization_numbers`	The realizations its simulations run as, from `0` to `N - 1`, or `[None]` for a single run.
`run_settings`	The settings that identify this variant's particles, as `_settings.yaml` records them.

Methods#

transport_for(realization)

Return the transport config realization realization runs with.
