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 jointly refining PFSS+IP field extrapolations against simultaneous remote-sensing (eclipse, EUV) and in-situ (L1, PSP, SolO) observations.
Layer 1 — Scientific invariant
Paper identity
- Title: Refinement of Global Coronal and Interplanetary Magnetic Field Extrapolations Constrained by Remote-Sensing and In-Situ Observations
- First author: TODO_verify
- Authors: TODO_verify
- Year: 2024
- arXiv: 2405.18665 (posted 2024-05-29)
- Journal: TODO_verify_with_full_text
- DOI: TODO_verify_with_full_text
Claim (narrow form)
A joint remote+in-situ refinement of PFSS+Parker-spiral extrapolations achieves better polarity-agreement at multiple spacecraft and improved eclipse-morphology matching than the baseline PFSS at fixed magnetogram product.
Method assumptions
- Multi-observable cost function is well-defined.
- Remote and in-situ observables are mutually compatible up to uncertainty.
Data assumptions
- Synoptic Br for the studied interval.
- Eclipse imagery (where available).
- L1+PSP+SolO in-situ B.
Failure modes (skill memory)
- Multi-objective optimization weights drive the optimum.
- Eclipse availability is sparse.
Figure / numerical targets
- Multi-observable cost surface.
- Per-spacecraft polarity-agreement improvement table.
Claim boundary
In scope. The studied intervals with multi-spacecraft coverage.
Out of scope — do NOT generalize:
- Do NOT cite the improvement scale outside the multi-observable coverage window.
- Do NOT collapse the joint refinement to a single-observable tune.
Layer 2 — Executable protocol (capability-typed)
Required capabilities (abstract)
| Capability | Purpose | Notes |
|---|
magnetogram.fetch_synoptic_br() | Br | |
pfss.solve() | PFSS | |
eclipse.angles() | eclipse-morphology metric | |
polarity.evaluate_multi_sc() | multi-spacecraft polarity | L1/PSP/SolO |
optim.multi_objective() | joint refinement | weights |
Procedure
- Build multi-objective cost: eclipse + polarity.
- Sweep PFSS parameters (R_ss, product).
- Optimize; record per-observable contribution.
Validation target
Reproduce per-spacecraft improvement table.
Layer 3 — Adapter / runtime notes (optional examples)
- sunkit-magex.pfss; pyspedas for in-situ.
Layer 4 — Research-generation affordances
- Compose with [[rice-2026-outflowpy-outflow-fields-pfss-alternative]] for a joint refinement under outflow physics.
- Generative hypothesis: cost-surface valleys identify regimes where additional physics (NSPF, multi-constraint PFSS) gives diminishing returns.
