ISEE-3: Propagated Solar Wind Magnetic Field Data at 60-Second Resolution

Propagated solar wind data from the ISEE-3 satellite, linearly interpolated to a 60-second resolution. The data consists of tri-axial fluxgate magnetometer measurements transformed into Geocentric Solar Magnetospheric (GSM) coordinates. This dataset was constructed by Dr. J.M. Weygand for Prof. R.L. McPherron under National Science Foundation grants and is used in superposed epoch studies of space weather.

Use Cases

• Modeling interplanetary magnetic field (IMF) propagation delays based on the described minimum variance technique.
• Conducting superposed epoch analyses of magnetospheric events using propagated solar wind parameters.
• Validating space weather prediction algorithms against propagated, minute-resolution magnetic field data.
• Studying the interaction of solar wind with Earth's bow shock and magnetopause using data propagated to a nominal position of 17 Earth radii.

Strengths

• Data is propagated to a consistent position just outside the nominal bow shock (approximately 17 Earth radii).
• Provides a 60-second temporal resolution for high-frequency analysis of solar wind variations.
• Based on a documented propagation method outlined in peer-reviewed publications by Dan Weimer et al.

Limitations

• The propagation method does not work well for shocks and minimum variance directions with tilts greater than 70 degrees from the sun-earth line.
• Column-level documentation is absent; field semantics and data structure must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment for large-scale ML tasks.
