MMS 2 Fast Plasma Investigation, Dual Ion Spectrometer (FPI, DIS) Partial Distribution Mom

NASA's Magnetospheric Multiscale mission provides high-resolution plasma data from its Fast Plasma Investigation instrument. This Level 2 product contains partial distribution moments calculated over a limited portion of velocity space, with data available at 0.15-second burst resolution within the mission's region of interest. The dataset includes time stamps and instrument state annotations, published by the National Aeronautics and Space Administration.

Use Cases

• Analyzing high-temporal-resolution plasma dynamics based on 0.15-second burst mode data
• Studying partial velocity space distributions based on 'density_part' and similar partial moments
• Correlating instrument state with plasma measurements based on included system annotation data
• Comparing plasma behavior inside and outside mission regions of interest based on different operational modes

Strengths

• Data originates from NASA's authoritative Magnetospheric Multiscale mission
• Provides high-resolution measurements at 0.15-second intervals in burst mode
• Includes instrument state annotations and time stamps for contextual analysis

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 per mission design
