ISEE-1: Propagated Solar Wind Data at 1-Minute Resolution

Propagated solar wind data from the ISEE-1 satellite at 1-minute resolution. The dataset includes linearly interpolated time delay, cosine angle, and goodness information, propagated to a position just outside the nominal bow shock. It was constructed by Dr. J.M. Weygand for Prof. R.L. McPherron under NSF grants and is based on a minimum variance technique for predicting IMF propagation delays.

Use Cases

• Modeling solar wind propagation times to Earth's bow shock based on the described minimum variance technique.
• Analyzing correlations between solar wind parameters and magnetospheric activity based on propagated data.
• Conducting superposed epoch studies of space weather events as referenced in the description.
• Validating or comparing propagation algorithms for interplanetary magnetic field data.

Strengths

• Data is at a high 1-minute temporal resolution.
• Propagation method is documented in peer-reviewed references (Weimer et al., 2003, 2004).
• Data originates from a NASA satellite mission and was created under NSF-funded studies.

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.
