MMS 2 FPI DES: Electron Phase Space Distributions at 30 ms Burst Resolution

NASA's Magnetospheric Multiscale (MMS) mission provides corrected electron phase space distribution maps from the Fast Plasma Investigation's Dual Electron Spectrometer. The data is collected in Burst Mode at 30-millisecond resolution within the mission's region of interest, with selected bursts downlinked for analysis. This Level 2 product includes time stamps and instrument state annotations for the released burst sky maps.

Use Cases

• Modeling electron velocity distribution functions based on the reported phase space maps.
• Analyzing high-temporal-resolution plasma dynamics using the 30 ms burst data.
• Studying instrument performance and data quality based on the included state annotations.
• Investigating magnetospheric phenomena within the MMS mission's region of interest.

Strengths

• Data originates from NASA's authoritative Magnetospheric Multiscale (MMS) mission.
• Provides high-resolution electron measurements at 30-millisecond intervals in burst mode.
• Includes corrected/converted distributions and instrument state annotations for quality assessment.

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, as per the mission design.
