STEREO-B PLASTIC: 1-Hour Solar Wind Proton Plasma Parameters

One-hour averaged solar wind proton parameters from the STEREO-B spacecraft. The data includes flow speed, density, temperature, thermal speed, velocity vector components, and statistical uncertainties. Produced by NASA's STEREO mission, 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 included STEREO radial distance and direction angles.

Strengths

• Includes statistical uncertainties and chi-squared values for data quality assessment.
• Provides velocity vector components and direction angles in multiple coordinate systems (HERTN, RTN, HEE, HEEQ, HCI).
• Data is sourced from a NASA spacecraft mission, indicating authoritative collection.

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.
