MMS 2 FPI DIS: Magnetospheric Plasma Distributions at 0.15-Second Burst Resolution

NASA's Magnetospheric Multiscale (MMS) mission provides corrected phase space distribution maps of ion and electron plasma from the Fast Plasma Investigation instrument. The data are collected in Burst Mode at 0.15-second resolution for ions and 0.03-second for electrons within the mission's region of interest. This Level 2 product contains selected downlinked burst data with timestamps and instrument state annotations, last updated in March 2026.

Use Cases

• Analyzing fine-scale plasma dynamics based on high-resolution 0.15-second ion distribution maps.
• Studying particle acceleration and energy transfer in Earth's magnetosphere based on burst mode phase space data.
• Modeling instrument system states and data quality based on the provided timestamps and annotations.
• Comparing burst resolution data with lower-resolution survey data for mission design validation.

Strengths

• Data is from NASA's authoritative Magnetospheric Multiscale mission.
• Provides high-resolution plasma measurements at 0.15 seconds for ions.
• Includes corrected 'Burst Sky Map' distributions with quality 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, only selected subsets.
