Wind Satellite: Solar Wind Magnetic Field Measurements at 60-Second Resolution

Wind satellite data processed to provide tri-axial magnetic field measurements at a consistent 60-second resolution in GSE coordinates. This dataset was constructed by Dr. J.M. Weygand for Prof. R.L. McPherron under NSF grants and includes a version 2 with a corrected offset in the Bz component after November 2004. It was primarily used for superposed epoch and cross-correlation studies of the solar wind.

Use Cases

• Conduct superposed epoch studies based on the processed solar wind data mentioned in the description.
• Perform cross-correlation analyses between solar wind parameters based on the dataset's stated purpose.
• Model space weather effects using corrected magnetic field components (Bz) as described.
• Validate magnetospheric models with high-resolution, interpolated magnetic field time series.

Strengths

• Data is processed and linearly interpolated to a consistent 1-minute resolution.
• Includes a corrected version (v2) addressing a known offset in the Bz component after November 2004.
• Created for specific NSF-funded studies (GEM Grant ATM 02-1798, Space Weather Grant ATM 02-08501).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total temporal coverage are unknown, which may limit suitability assessment.
• Data freshness should be verified despite a last updated metadata date of 2026-03-13.

Collection Method

Processed solar wind data linearly interpolated to 1-minute resolution using MATLAB's interp1.m function.

Time Range

Coverage includes data from at least 1999 onward, with a noted correction after November 2004.
