IMP-8: Interpolated 60-Second Magnetic Field Measurements in GSM Coordinates

IMP-8 linearly interpolated tri-axial fluxgate magnetometer data provides processed solar wind measurements at a 60-second resolution in GSM coordinates. The dataset was constructed by Dr. J.M. Weygand for Prof. R.L. McPherron under NSF grants ATM 02-1798 and ATM 02-08501. It was primarily used for superposed epoch and cross-correlation studies of solar wind phenomena.

Use Cases

• Conduct superposed epoch analysis based on the interpolated 60-second magnetic field time series.
• Perform cross-correlation studies of solar wind parameters based on the processed magnetometer data.
• Model magnetopause and bow shock interactions based on tri-axial magnetic field measurements.
• Analyze solar wind variability based on the linearly interpolated time-series data.

Strengths

• Data is processed and linearly interpolated to a consistent 60-second resolution.
• Data originates from the IMP-8 spacecraft, a recognized NASA mission.
• Dataset was developed under specific NSF grants (ATM 02-1798 and ATM 02-08501) for scientific studies.

Limitations

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