Geotail CPI: Solar Wind Plasma Measurements at 60-Second Resolution

Geotail spacecraft data processed to provide solar wind plasma measurements at a 60-second resolution in GSM coordinates. This dataset was constructed by Dr. J.M. Weygand for Prof. R.L. McPherron under NSF grants ATM 02-1798 and ATM 02-08501. It has been used for superposed epoch and cross correlation studies on solar wind phenomena.

Use Cases

• Perform superposed epoch analysis based on the linearly interpolated 1-minute solar wind data.
• Conduct cross correlation studies on solar wind parameters using the processed time-series.
• Analyze magnetospheric response to solar wind variations based on spacecraft position data.
• Model solar wind-magnetosphere coupling using the high-resolution plasma measurements.

Strengths

• Data is linearly interpolated to a consistent 60-second resolution, facilitating time-series analysis.
• Dataset was constructed for and used in specific NSF-funded research projects (GEM Grant ATM 02-1798, 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 for large-scale analyses.
