MMS 4 FPI: Partial Plasma Distribution Moments from Burst Mode

Burst mode data at 0.15-second resolution from the Magnetospheric Multiscale (MMS) mission's Fast Plasma Investigation Dual Ion Spectrometer. The dataset contains partial distribution moments, such as density_part, calculated over a limited portion of velocity space, and is produced by NASA. The last metadata update was recorded on 2026-03-13.

Use Cases

• Analyzing high-temporal-resolution ion dynamics based on 0.15-second burst mode data.
• Studying partial plasma moments like density_part to understand specific regions of velocity space.
• Correlating plasma parameters with magnetic and electric field data from the same mission.
• Investigating instrument performance and calibration states based on included annotation parameters.

Strengths

• Data is collected at high-resolution burst mode (0.15 seconds for DIS).
• Includes specialized partial moments (e.g., density_part) not found in standard moment products.
• Produced by the authoritative space agency NASA.
• Metadata indicates recent platform activity as of 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 availability is partial, as not all burst resolution data are downlinked per mission design.
