MMS 3 FPI-DES: Magnetospheric Plasma Distributions at 30 ms Burst Resolution

NASA's Magnetospheric Multiscale (MMS) mission provides corrected phase space distribution maps of electrons from the Fast Plasma Investigation's Dual Electron Spectrometer. The data are captured in Burst Mode at 30-millisecond resolution within the mission's region of interest, representing the highest quality corrected distributions available at release. This dataset contains selected downlinked burst data from the MMS 3 spacecraft, with time stamps and instrument state annotations.

Use Cases

• Analyze high-temporal-resolution electron phase space distributions based on the 30 ms burst data.
• Study magnetospheric plasma dynamics and particle acceleration processes based on the instrument's region of interest.
• Validate and calibrate plasma physics models based on the corrected/converted 'Burst Sky Map' distributions.
• Investigate instrument system state correlations with plasma measurements based on the provided time stamps and annotations.

Strengths

• Data is captured at a high temporal resolution of 30 milliseconds for electron measurements.
• Distributions are corrected and converted to represent the highest possible quality at the time of release.
• Data includes time stamps and annotations characterizing the state of the instrument system.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Not all burst resolution data are downlinked; this product contains only the selected subset.
• Row count is unknown, which may limit suitability assessment.
