ISEE-1: Propagated Solar Wind Magnetic Field Data at 60-Second Resolution

ISEE-1 satellite data processed using a minimum variance technique to propagate solar wind measurements to a point just outside Earth's bow shock. The data, originally constructed by Dr. J.M. Weygand for NSF studies, has been linearly interpolated to a uniform 60-second resolution in GSM coordinates. This dataset was used in superposed epoch studies for space weather research.

Use Cases

• Modeling the propagation delay of the interplanetary magnetic field (IMF) based on the described minimum variance technique.
• Conducting superposed epoch analysis of solar wind events based on the dataset's stated primary use.
• Analyzing correlations between solar wind parameters and magnetospheric activity based on propagated, time-aligned data.
• Validating or improving solar wind propagation models based on the Weimer method outlined in the references.

Strengths

• Data is processed to a consistent 60-second temporal resolution, facilitating time-series analysis.
• Propagation method is documented with specific references to peer-reviewed publications (Weimer et al., 2003, 2004).
• Dataset provenance is clearly stated, originating from Dr. J.M. Weygand for NSF-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, as stated in the description.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment for large-scale projects.
