Runtime-neutral paper-skill. Layered: (1) scientific invariants, (2) executable protocol against abstract capabilities, (3) adapter notes (optional examples only), (4) research-generation affordances.
Trigger
Reach for this skill when validating Alfvén-wave-driven solar-wind models against IPS-derived vsw maps, using PFSS to constrain source-region magnetic geometry.
Layer 1 — Scientific invariant
Paper identity
- Title: Testing the Alfvén-Wave Model of the Solar Wind with Interplanetary Scintillation
- First author: TODO_verify
- Authors: TODO_verify
- Year: 2022
- arXiv: 2202.10768 (posted 2022-02-22)

- DOI: TODO_verify_with_full_text
Claim (narrow form)
Alfvén-wave-driven wind models reproduce IPS-derived global vsw maps within tolerance when PFSS provides realistic expansion-factor inputs; residuals are dominated by polar / high-latitude regions.
Method assumptions
- IPS inversion gives reliable vsw on a global grid.
- Alfvén-wave model is consistent with expansion-factor inputs.
Data assumptions
- IPS vsw maps for the studied interval.
- Synoptic Br for PFSS.
Failure modes (skill memory)
- IPS inversion is grid-resolution-dependent.
- Polar coverage is sparse in IPS.
Figure / numerical targets
- Model-vs-IPS vsw map.
- Residuals vs heliographic latitude.
Claim boundary
In scope. The IPS coverage + paper's Alfvén-wave model.
Out of scope — do NOT generalize:
- Do NOT cite the model agreement for polar latitudes outside IPS coverage.
- Do NOT extend to non-IPS-validated intervals.
Layer 2 — Executable protocol (capability-typed)
Required capabilities (abstract)
| Capability | Purpose | Notes |
|---|
ips.fetch_vsw_map() | IPS-derived vsw | |
magnetogram.fetch_synoptic_br() | Br | |
pfss.solve() | PFSS | |
expansion_factor.compute() | f at SS | |
alfven_wave.model_speed() | AW-model vsw | |
Procedure
- Fetch IPS vsw maps.
- Solve PFSS; compute f at SS.
- Run AW model; predict vsw on the global grid.
- Compare to IPS; quantify residuals by latitude.
Validation target
Recover the global agreement and polar residuals.
Layer 3 — Adapter / runtime notes (optional examples)
- sunkit-magex.pfss; AW model is paper-specific.
Layer 4 — Research-generation affordances
- Compose with [[mostl-2022-alfven-wave-solar-wind-ip-scintillation]] + [[reville-2025-solo-psp-open-closed-magnetic-outflows]] for IPS↔in-situ joint validation.
- Generative hypothesis: IPS residuals at high latitudes correlate with polar-completeness ensembles ([[sasi-2025-uncertainty-solar-wind-incomplete-magnetic-field]]).
