IMP-8: Propagated Solar Wind Magnetic Field Measurements at 60-Second Resolution

IMP-8 satellite data propagated to a position near Earth's bow shock and interpolated to 60-second resolution. The dataset consists of tri-axial fluxgate magnetometer measurements in GSE coordinates, originally constructed by Dr. J.M. Weygand for NSF-funded studies. These data were primarily used in superposed epoch analyses of solar wind phenomena.

Use Cases

• Analyzing solar wind propagation delays based on the described minimum variance technique.
• Studying magnetic field behavior near Earth's bow shock using the propagated 1-minute resolution data.
• Conducting superposed epoch studies of space weather events as referenced in the description.
• Modeling interplanetary magnetic field (IMF) interactions with Earth's magnetosphere.

Strengths

• Data is processed to a consistent 60-second temporal resolution.
• Propagation method is documented with specific references to peer-reviewed publications (Weimer et al., 2003, 2004).
• Dataset was constructed for and used in National Science Foundation-funded research projects.

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 is unknown, which may limit suitability assessment.
