Van Allen Probe EFW Burst Mode Electric and Magnetic Fields

Van Allen Probe A Electric Field and Waves Suite (EFW) Burst Mode 1 provides targeted measurements of 3-D electric fields, 3-D wave magnetic fields, and spacecraft potential at 512 samples per second. The dataset includes components in spacecraft spin coordinates and is produced by the National Aeronautics and Space Administration. Burst Mode 1 data collection and playback are requested on the ground.

Use Cases

• Analyze wave-particle interactions based on simultaneous electric and magnetic field measurements.
• Study plasma wave propagation based on three-dimensional waveform data.
• Investigate spacecraft charging effects based on spacecraft-sensor potential measurements.
• Detect large amplitude signals near 1 kHz based on onboard triggering algorithm logic.

Strengths

• Provides three-dimensional measurements of both electric and magnetic fields.
• Includes two distinct burst modes (B1 and B2) with different sampling rates (512 and 16384 samples/s).
• Data is in spacecraft-specific 'uvw' coordinates, which likely aids in physical interpretation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
