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

Linearly interpolated solar wind plasma measurements from the Geotail spacecraft, processed to a uniform 60-second resolution. This dataset was constructed by Dr. J.M. Weygand for Prof. R.L. McPherron's National Science Foundation studies on geomagnetic storms. It was primarily used for superposed epoch and cross-correlation analyses of solar wind phenomena.

Use Cases

• Conduct superposed epoch studies based on the processed solar wind time series.
• Perform cross-correlation analyses between solar wind parameters and magnetospheric activity.
• Model solar wind propagation and its effects on space weather based on the interpolated plasma data.
• Validate magnetospheric simulation inputs using the 60-second resolution spacecraft measurements.

Strengths

• Data is processed to a uniform 60-second resolution, facilitating time-series analysis.
• Created for specific NSF-funded studies (GEM Grant ATM 02-1798, Space Weather Grant ATM 02-08501), indicating a research-grade purpose.
• Last updated metadata indicates recent platform activity (2026-03 13).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total data size are unknown, which may limit suitability assessment.
• Data format includes BIN files, which may require specific tools or knowledge to access.
