STEREO-B PLASTIC: Solar Wind Proton Plasma Parameters

STEREO-B satellite data provides 10-minute averaged solar wind proton flow speed, density, and temperature. The records include velocity vector components, statistical uncertainties, and spacecraft position information. This dataset is produced by NASA and was last updated in March 2026.

Use Cases

• Model solar wind propagation based on proton flow speed and density.
• Analyze plasma flow direction based on velocity vector components in HERTN and RTN coordinates.
• Assess measurement reliability based on included chi-squared and statistical uncertainties.
• Correlate plasma parameters with spacecraft position based on radial distance and HEE, HEEQ, HCI direction angles.

Strengths

• Data includes statistical uncertainties and chi-squared values for quality assessment.
• Records contain spacecraft position information in multiple coordinate systems.
• Proton plasma parameters are averaged over a consistent 10-minute interval.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
