Geotail Magnetometer Data: Solar Wind Measurements at 60-Second Resolution

Linearly interpolated tri-axial fluxgate magnetometer data from the Geotail spacecraft, processed to a 60-second resolution in GSE 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. It originates from NASA and was last updated in March 2026.

Use Cases

• Perform superposed epoch analysis based on the interpolated 1-minute solar wind magnetic field data.
• Conduct cross-correlation studies between solar wind parameters based on the processed magnetometer measurements.
• Analyze magnetotail or magnetopause dynamics based on spacecraft-position magnetic field data.
• Validate or calibrate solar wind models based on the interpolated tri-axial fluxgate magnetometer readings.

Strengths

• Data is processed to a consistent 60-second resolution via linear interpolation.
• Magnetic field measurements are provided in the GSE coordinate system, a standard for solar wind analysis.
• Dataset was constructed for specific NSF-funded studies (GEM Grant ATM 02-1798 and Space Weather Grant ATM 02-08501).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
