❓ Expert Physics FAQ

How do I interpret the physics model confidence scores? +

Confidence scores reflect historical validation against observations. >80% indicates models consistently perform well for similar conditions. Lower scores suggest either challenging conditions or limited historical data for validation.

What makes the Burton Dst model accurate for geomagnetic storms? +

The Burton model captures the main physical drivers: solar wind dynamic pressure (compression) and IMF Bz (magnetic reconnection). The -0.01V²Bz term represents the injection function, while the √P_dyn term accounts for magnetopause compression effects.

How accurate are the CME arrival time predictions? +

The drag-based model typically achieves ±8-12 hour accuracy for arrival times. Faster CMEs (>1000 km/s) have higher accuracy due to less solar wind interaction. The R² = 0.89 represents correlation with observed events.

Can I export the physics model outputs for my research? +

Yes! Use the screenshot capture for visualizations. For raw data access, contact our technical support for API integration options. We support research collaborations and can provide model outputs in standard formats.
