MMS SCM: AC Magnetic Field Waveforms at 8192 Samples/Second

8192 samples per second of tri-axial AC magnetic field waveforms in nanoTesla, measured in the GSE frame by the MMS spacecraft's Search Coil Magnetometer. The data is Level 2 processed, includes burst mode acquisitions within scientific regions of interest, and was produced by NASA. The dataset was last updated on March 13, 2026.

Use Cases

• Analyze high-frequency magnetic wave properties based on the 8192 samples/second AC waveform data.
• Study three-dimensional magnetic field fluctuations in regions of interest based on the tri-axial measurements.
• Validate instrument calibration and transfer functions based on the described onboard calibration signal.
• Model magnetospheric dynamics based on the GSE-frame magnetic field data from the MMS mission.

Strengths

• Data is calibrated, with pre-launch calibration performed at the National Magnetic Observatory and onboard calibration checks per orbit.
• Provides high-temporal-resolution AC magnetic field waveforms at 8192 samples per second.
• Includes data from specific scientific Regions Of Interest (ROI) where burst mode was activated.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total dataset size are unknown, which may limit suitability assessment.
• Data is provided in a BIN file format, which may require specialized tools for access and processing.
