Geotail: 60-Second Magnetic Field Measurements in GSM Coordinates

Geotail satellite magnetic field data linearly interpolated to 60-second resolution in GSM coordinates. The processed solar wind data was constructed by Dr. J.M. Weygand for Prof. R.L. McPherron for NSF studies GEM Grant ATM 02-1798 and Space Weather Grant ATM 02-08501. These data were primarily used in superposed epoch and cross correlation studies on solar wind.

Use Cases

• Conduct superposed epoch studies based on processed solar wind data.
• Perform cross correlation studies on solar wind based on interpolated magnetic field measurements.
• Analyze magnetospheric dynamics based on tri-axial fluxgate magnetometer data.
• Model solar wind interactions with Earth's magnetic field based on spacecraft-position interpolated data.

Strengths

• Data is processed and linearly interpolated to a consistent 60-second resolution.
• Data is referenced to GSM coordinates, a standard frame for magnetospheric studies.
• Dataset was constructed for and used in specific NSF-funded research projects.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect temporal bias inherent to the Geotail mission's operational period.
