ISEE-2: 60-Second Solar Wind Magnetic Field Measurements in GSM Coordinates

Linearly interpolated tri-axial fluxgate magnetometer data from the ISEE-2 spacecraft, processed to a 60-second resolution in Geocentric Solar Magnetospheric (GSM) coordinates. The dataset was constructed by Dr. J.M. Weygand for Prof. R.L. McPherron for use in superposed epoch and cross-correlation studies on solar wind phenomena. It originates from NASA and was last updated in March 2026.

Use Cases

• Conduct superposed epoch analysis based on the processed solar wind time-series data.
• Perform cross-correlation studies between solar wind parameters and magnetospheric activity.
• Model solar wind-magnetosphere coupling using the interpolated magnetic field measurements.
• Validate magnetospheric simulation outputs against historical in-situ satellite observations.

Strengths

• Data is processed and linearly interpolated to a consistent 1-minute resolution.
• Originates from a NASA satellite mission, suggesting authoritative source data.
• Specifically designed for statistical studies like superposed epoch and cross-correlation analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• Data may reflect temporal bias inherent to the specific ISEE-2 mission period.
