ACE SWEPAM: Solar Wind Plasma Data at 60-Second Resolution

Linearly interpolated solar wind plasma measurements from the Advanced Composition Explorer (ACE) satellite at a 60-second resolution in GSE coordinates. This processed data set 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 on solar wind phenomena.

Use Cases

• Conduct superposed epoch analysis based on the processed solar wind time series mentioned in the description.
• Perform cross-correlation studies between solar wind parameters and geomagnetic indices based on the data's intended use.
• Model solar wind propagation and its impact on Earth's magnetosphere based on the high-resolution plasma measurements.
• Validate space weather forecasting models based on the ACE satellite's solar wind observations.

Strengths

• Data is processed and linearly interpolated to a consistent 60-second temporal resolution.
• Originates from the ACE satellite, a key source for solar wind monitoring.
• Created for specific NSF-funded research projects (GEM Grant ATM 02-1798 and Space Weather Grant ATM 02 08501).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• Data is provided in HTML format, which may require conversion for typical time-series analysis.
