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

8192 samples per second AC magnetic field waveforms from the Magnetospheric Multiscale mission's Search-Coil Magnetometer. The tri-axial instrument measures three-dimensional magnetic field fluctuations in nanoTesla, calibrated at the National Magnetic Observatory and checked via onboard signals. NASA provides this Level 2 burst mode data for scientific regions of interest.

Use Cases

• Analyze high-frequency magnetic wave spectra based on 8192 Hz waveform data
• Study three-dimensional magnetic field fluctuations in the GSE coordinate frame
• Validate instrument calibration using onboard calibration signals mentioned in the description
• Compare burst mode data with survey mode data for regions of scientific interest

Strengths

• Data is calibrated at the National Magnetic Observatory, Chambon-la-Foret
• Onboard calibration signal checks the transfer function once per orbit
• Provides waveforms at a high sampling rate of 8192 samples per second

Limitations

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