MMS FPI DIS: Partial Plasma Distribution Moments from Burst Mode

Burst mode data at 0.15-second resolution from the MMS mission's Dual Ion Spectrometer, collected by NASA. The dataset contains partial moments, which are standard moment integrals calculated over a limited portion of velocity space. These parameters are augmented with time stamps and instrument state annotations.

Use Cases

• Analyzing high-time-resolution plasma dynamics based on burst mode data mentioned in the description.
• Studying partial velocity space distributions based on the 'partial moments' concept described.
• Correlating instrument state with plasma measurements based on the included time stamps and annotations.
• Investigating ion behavior in different mission phases (Fast Survey, Slow Survey) based on the operational modes described.

Strengths

• Data originates from NASA's Magnetospheric Multiscale (MMS) mission, a major space physics project.
• Includes high-resolution burst mode data at 0.15 seconds for the Dual Ion Spectrometer.
• Provides partial moments, a specialized data product for analyzing limited velocity space regions.
• Last metadata update was recorded on 2026-03-13 06:13:19.323614.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data availability is partial, as not all burst resolution data are downlinked per the mission design.
