MMS 4 Fast Plasma Investigation: Partial Plasma Moments from Dual Ion Spectrometer

Partial plasma moments data from the Magnetospheric Multiscale (MMS) mission's Fast Plasma Investigation instrument, collected at 4.5-second survey resolution. The dataset is produced by the National Aeronautics and Space Administration and contains derived quantities like density_part, integrated over a limited portion of velocity space. Data includes timestamps and instrument status annotations, with the last metadata update recorded on 2026-03-13.

Use Cases

• Analyzing plasma density and velocity distributions based on partial moment integrals.
• Studying magnetospheric region-of-interest phenomena based on the Fast Survey Mode data.
• Correlating plasma parameters with magnetic and electric field data based on the platform tags.
• Investigating instrument calibration and operational state based on the included status annotations.

Strengths

• Data originates from the authoritative NASA MMS mission.
• Includes specific derived parameters like partial density moments.
• Metadata indicates a recent update on 2026-03-13.

Limitations

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