MMS EDI: Ambient Electron Flux Measurements at 1024 Samples/Second

Electron flux data from the Magnetospheric Multiscale (MMS) mission's Electron Drift Instrument (EDI) in ambient burst survey mode. The National Aeronautics and Space Administration (NASA) produced this Level 2 dataset, which captures high-resolution measurements at 1024 samples per second (0.9765625 ms). Data includes beam firing directions, times-of-flight, quality indicators, and timestamps from the instrument's field-aligned sampling mode.

Use Cases

• Analyzing high-frequency variations in ambient electron fluxes based on the 1024 Hz sampling rate.
• Studying field-aligned electron pitch angle distributions based on the instrument's described sampling mode.
• Investigating signal-to-noise ratio (SNR) thresholds for particle detection in space plasma instruments.
• Modeling electron beam detection and tracking algorithms based on the described gun deflection and correlator system.

Strengths

• Data is collected at a high temporal resolution of 1024 samples per second.
• Produced by the National Aeronautics and Space Administration, a authoritative space agency.
• Includes quality indicators and timestamps for beam hits, as described.

Limitations

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