IMP-8 Solar Wind Plasma Data at 60-Second Resolution

IMP-8 spacecraft data processed to provide solar wind measurements at a 60-second resolution. The dataset consists of linearly interpolated plasma data in GSM coordinates, originally constructed by Dr. J.M. Weygand for Prof. R.L. McPherron. It was primarily used in superposed epoch and cross correlation studies on solar wind phenomena.

Use Cases

• Conduct superposed epoch studies based on the processed solar wind data.
• Perform cross correlation studies based on the interpolated plasma measurements.
• Analyze solar wind dynamics based on the 60-second resolution time series.
• Model magnetospheric interactions based on data in GSM coordinates.

Strengths

• Data is linearly interpolated to a consistent 60-second resolution.
• Coordinates are specified as GSM, a standard reference frame for space physics.
• Dataset was constructed for and used in National Science Foundation-funded studies.

Limitations

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