Aligns independent geomagnetic reconstructions to highlight when unusual events coincide.
For Everyone
Earth's magnetic field sometimes weakens, wobbles, or nearly flips. TRP brings together multiple reconstructions to show where unusual periods line up. Where independent models agree, confidence grows.
- How often large disturbances occur
- Which periods are best constrained
- Transparent data lineage for exploration
For Researchers
TRP operationalizes cross-dataset temporal alignment of geomagnetic excursions through:
- Charlie Index (C): cross-model alignment proxy (0–1)
- Charlie Prime (C′): change rate
- ΔZ*: divergence diagnostics across time
All time axes: kyr BP (Present = 1950). Descriptive weights: temporal_offset = 0.3, dataset_count = 0.7.
Key Figures
- Multistack Coverage (agreement over time)
- Divergence Panels (ΔZ* multi-view)
Exploratory Alignment: No Curve Fitting
This 4-panel divergence chart shows TRP's ΔZ* applied to the PADM2M paleomagnetic dataset. The shaded bands indicate independently published age ranges for major geomagnetic events (Olduvai, Jaramillo, Matuyama, Laschamp, etc.).
Important notes:- Bands are independent of TRP outputs.
- No curve fitting; plotted geometry reflects raw ΔZ* values.
- Alignment is emergent, not imposed.
