Wind 3DP: Propagated Solar Wind Data at 60-Second Resolution

Propagated solar wind data from the Wind spacecraft, linearly interpolated to a 60-second resolution at a position just outside Earth's nominal bow shock (approximately 17, 0, 0 Re). The dataset was constructed by Dr. J.M. Weygand for Prof. R.L. McPherron, a principal investigator for two National Science Foundation studies, and was primarily used in superposed epoch studies. A version 2 exists with a corrected offset found in the Wind MFI Bz component after November 2004.

Use Cases

• Modeling interplanetary magnetic field (IMF) propagation delays based on the described minimum variance technique.
• Conducting superposed epoch studies of magnetospheric events using propagated solar wind parameters.
• Analyzing solar wind conditions upstream of Earth's bow shock at a consistent 1-minute cadence.
• Correcting instrumental offsets in magnetic field data based on the provided Bz correction formula.

Strengths

• Data is propagated to a consistent reference point just outside the bow shock (approximately 17, 0, 0 Re).
• Time resolution is standardized to 60 seconds through linear interpolation.
• A corrected version (Version 2) addresses a known instrumental offset in the Bz component.
• Construction and methodology are documented in peer-reviewed references (Weimer et al., 2003, 2004).

Limitations

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