IMP-8: Linearly Interpolated 60-Second Solar Wind Magnetic Field Data

Linearly interpolated tri-axial fluxgate magnetometer data from the IMP-8 spacecraft, processed to a 60-second resolution in GSE coordinates. This processed solar wind data set was constructed by Dr. J.M. Weygand for Prof. R.L. McPherron under NSF grants ATM 02-1798 and ATM 02-08501. The data were primarily used in superposed epoch and cross-correlation studies on solar wind phenomena.

Use Cases

• Conduct superposed epoch analysis based on the processed solar wind time series mentioned in the description
• Perform cross-correlation studies between solar wind parameters based on the interpolated magnetic field data
• Model solar wind-magnetosphere coupling based on the tri-axial magnetic field measurements in GSE coordinates

Strengths

• Data is processed and linearly interpolated to a consistent 60-second resolution
• Originates from a NASA satellite mission and was constructed for specific NSF-funded research studies
• Coordinates are specified as GSE, providing a standardized reference frame for analysis

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count and original temporal coverage are unknown, which may limit suitability assessment
