ISEE-3 Solar Wind Propagation Data at 1-Minute Resolution

ISEE-3 spacecraft data provides solar wind parameters propagated to Earth's bow shock at a 1-minute cadence. Dr. J.M. Weygand constructed this dataset for Prof. R.L. McPherron's NSF-funded studies on geomagnetic phenomena. The propagation method uses a minimum variance technique detailed in Weimer et al. [2003; 2004].

Use Cases

• Analyzing solar wind propagation delays based on the described minimum variance technique.
• Conducting superposed epoch studies of magnetospheric events using the 1-minute resolution data.
• Modeling the interaction of the solar wind with Earth's magnetic field using propagated parameters.
• Investigating the limitations of propagation methods for shocks and high-tilt conditions mentioned in the description.

Strengths

• Data is processed to a high temporal resolution of 1 minute.
• Propagation method is documented with specific references to peer-reviewed publications.
• Dataset was constructed for use in National Science Foundation-funded research projects.

Limitations

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