MMS 3 FPI DIS: Magnetospheric Plasma Particle Distributions at 4.5-Second Resolution

NASA's Magnetospheric Multiscale (MMS) mission provides corrected phase space distribution maps from the Fast Plasma Investigation's Dual Ion Spectrometer. Data are aggregated onboard from high-resolution burst observations and reported at a 4.5-second survey resolution. This Level 2 product includes timestamps and instrument state annotations for the MMS Region of Interest.

Use Cases

• Modeling magnetospheric plasma dynamics based on ion phase space distribution maps.
• Analyzing particle behavior in the MMS Region of Interest based on aggregated survey resolution data.
• Calibrating or validating space weather models based on instrument state annotations and timestamps.
• Studying temporal evolution of plasma phenomena based on the 4.5-second resolution time series.

Strengths

• Data originates from NASA's authoritative Magnetospheric Multiscale (MMS) mission.
• Includes corrected 'Fast Survey Sky Map' distributions representing the highest quality at the time of release.
• Provides instrument state annotations and timestamps for each 4.5-second observation period.

Limitations

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