CORALL: Interball-1 Satellite Solar Wind Plasma Data at 60-Second Resolution

NASA's Interball-1 satellite data provides processed solar wind plasma measurements from the CORALL instrument, linearly interpolated to a 60-second resolution in GSE 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 on solar wind phenomena.

Use Cases

• Conduct superposed epoch analyses based on the processed solar wind time series mentioned in the description
• Perform cross-correlation studies between solar wind parameters and magnetospheric activity
• Model space weather events using the 60-second resolution plasma data
• Validate magnetospheric simulation outputs against in-situ satellite measurements

Strengths

• Data is processed and linearly interpolated to a consistent 60-second temporal resolution
• Created for specific NSF-funded studies (GEM Grant ATM 02-1798 and Space Weather Grant ATM 02 08501)
• Coordinates are specified as Geocentric Solar Ecliptic (GSE), a standard for space physics

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Description metadata is limited; actual data quality requires manual inspection after download
