Wind MFI: Magnetic Field Vector and Spacecraft Position Data at 92-Second Intervals

Wind spacecraft magnetic field vector and spacecraft position data from the Magnetic Fields Investigation (MFI) instrument. The dataset provides key parameter (K0) measurements in both GSE and GSM coordinate systems at 92-second intervals. It was produced by the National Aeronautics and Space Administration (NASA) and last updated in March 2026.

Use Cases

• Modeling solar wind interactions with Earth's magnetosphere based on magnetic field vector data.
• Analyzing spacecraft trajectory and orientation for instrument calibration based on ephemeris data.
• Correlating magnetic field disturbances with other space weather phenomena based on time-series measurements.

Strengths

• Data is associated with the NASA Wind spacecraft mission, a recognized source for heliophysics.
• References include operator manuals and data format control documents, suggesting structured documentation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is stored in BIN format, which may require specialized tools for access.
