Wind SWE Propagated Solar Wind Data at 60-Second Resolution

Propagated solar wind data from the Wind spacecraft, linearly interpolated to a 60-second resolution in GSE coordinates. The data was constructed by Dr. J.M. Weygand for Prof. R.L. McPherron under NSF grants ATM 02-1798 and ATM 02-08501, primarily for superposed epoch studies. The propagation method is based on the minimum variance technique described by Dan Weimer et al. in 2003 and 2004.

Use Cases

• Modeling solar wind propagation delays to Earth's magnetosphere based on the described minimum variance technique.
• Conducting superposed epoch analyses of magnetospheric activity using propagated solar wind parameters.
• Validating space weather prediction models that rely on time-shifted solar wind data.
• Studying the statistical properties of the solar wind upstream of Earth's bow shock at a consistent 1-minute cadence.

Strengths

• Data is propagated to a consistent reference point just outside the nominal bow shock (approximately 17, 0, 0 Re).
• Temporal resolution is standardized to 60 seconds through linear interpolation.
• Construction and methodology are documented in peer-reviewed publications (Weimer et al., 2003, 2004).
• Data provenance is clearly stated, originating from Dr. J.M. Weygand and funded by specific NSF grants.

Limitations

• The propagation method does not work well for shocks and minimum variance directions with tilts greater than 70 degrees from the sun-earth line.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and exact data volume are unknown, which may limit suitability assessment.
