MMS Fast Plasma Investigation: Electron Spectrometer Distributions at 30 ms Resolution

Phase space distribution maps of electron plasma data collected by the Magnetospheric Multiscale (MMS) mission's Fast Plasma Instrument. The data are from the Dual Electron Spectrometer (DES) in Burst Mode at 30-millisecond resolution, representing a subset selected for downlink. The dataset is produced by NASA and was last updated on March 13, 2026.

Use Cases

• Analyzing high-resolution plasma dynamics based on 30 ms burst mode data
• Studying electron phase space distributions based on corrected 'Burst Sky Map' data
• Investigating magnetospheric phenomena based on instrument state annotations

Strengths

• Data provides high temporal resolution at 30 milliseconds for electron measurements
• Distributions are corrected and converted for highest possible quality at release
• Data includes time stamps and instrument state annotations

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Not all burst resolution data are downlinked; this product contains only a selected subset
