STEREO-B PLASTIC: Solar Wind Alpha Particle Plasma Parameters

10-minute averaged values of solar wind alpha particle flow speed, density, thermal speed, alpha to proton density ratio, and proton-alpha flow speed difference. The data product was created by the National Aeronautics and Space Administration. It was last updated on March 13, 2026.

Use Cases

• Model solar wind propagation based on alpha particle flow speed.
• Analyze plasma composition based on the alpha to proton density ratio.
• Study thermal properties of solar wind based on alpha particle thermal speed.
• Investigate differential flow dynamics based on proton-alpha flow speed difference.
• Calculate plasma density and mass flux based on alpha particle density.

Strengths

• Data is averaged over 10-minute intervals, providing a consistent temporal resolution.
• Contains multiple derived plasma parameters (flow speed, density, thermal speed, ratios, differences).
• Produced by the authoritative organization National Aeronautics and Space Administration.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
