MMS Fast Plasma Instrument: Electron Spectrometer Distributions

Fast survey mode plasma distribution maps from the Magnetospheric Multiscale mission's Dual Electron Spectrometer instrument. The National Aeronautics and Space Administration provides corrected phase space distribution maps aggregated to 4.5-second resolution from higher-resolution onboard observations. Data were last updated on March 13, 2026.

Use Cases

• Analyze plasma phase space distributions based on corrected Fast Survey Sky Maps
• Study magnetospheric particle behavior based on aggregated 4.5-second resolution data
• Model instrument system states based on annotated time stamps and instrument state metadata

Strengths

• Data is from the NASA Magnetospheric Multiscale mission, a recognized scientific source
• Provides corrected/converted distributions described as the highest possible quality at the time of release

Limitations

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