Description
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.
