STEREO-B: Hourly Solar Wind and Particle Measurements

Hourly averaged data from the Solar Terrestrial Relations Observatory-B satellite, processed by NASA's NSSDC COHOWeb system. The data includes magnetic field averages, solar wind proton and ion densities, speeds, velocity vectors, temperatures, and energetic particle fluxes from multiple onboard instruments. The dataset was last updated on March 13, 2026.

Use Cases

• Modeling solar wind propagation based on proton and ion density and speed measurements.
• Analyzing magnetic field perturbations associated with coronal mass ejections based on fluxgate magnetometer data.
• Studying energetic particle events in the heliosphere based on fluxes from the Low Energy Telescope, High Energy Telescope, and Suprathermal Ion Telescope.

Strengths

• Data originates from NASA's STEREO-B satellite, a dedicated solar observation mission.
• Hourly averages are derived from high-resolution 10-minute data, suggesting a consistent temporal resolution.
• Includes measurements from multiple specialized instruments (IMPACT, PLASTIC, SEP suite) for a multi-faceted view.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• File formats include BIN and HTML, which may require specialized tools for analysis.
