ACE Weimer Propagated Solar Wind and Magnetic Field Data at 60-Second Resolution

Propagated solar wind and magnetic field data from the ACE satellite, linearly interpolated to a consistent 60-second resolution in GSM coordinates. The data was constructed by Dr. J.M. Weygand for Prof. R.L. McPherron under NSF grants ATM 02-1798 and ATM 02-08501, primarily for superposed epoch studies. The propagation method, based on the minimum variance technique, is detailed in peer-reviewed publications by Dan Weimer et al. from 2003 and 2004.

Use Cases

• Modeling magnetospheric response based on propagated solar wind parameters.
• Conducting superposed epoch analyses of space weather events based on the dataset's stated purpose.
• Validating solar wind propagation algorithms based on the described minimum variance technique.
• Studying interplanetary magnetic field (IMF) propagation delays based on the referenced methodology.

Strengths

• Data is propagated to a consistent reference point just outside Earth's bow shock (about 17, 0, 0 Re).
• Uses a peer-reviewed propagation method (minimum variance technique) documented in J. Geophys. Res. publications.
• Time resolution is standardized to 60 seconds through linear interpolation.

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.
