PSP SWEAP SPAN-B: Electron Pitch Angle Distributions from Parker Solar Probe

NASA's Parker Solar Probe SWEAP instrument provides Level 3 measurements of Electron Pitch Angle Distributions from the SPAN-B sensor. The data is structured in 13.981-second intervals and is governed by specific collaboration rules for scientific use. The dataset was last updated on March 13, 2026.

Use Cases

• Modeling solar wind electron behavior based on pitch angle distribution measurements.
• Analyzing particle dynamics in the inner heliosphere based on high-cadence time-series data.
• Validating space weather forecasting models based on in-situ particle observations from the Parker Solar Probe.

Strengths

• Data originates from the NASA Parker Solar Probe mission, a primary source for near-Sun measurements.
• Measurements are provided at a regular 13.981-second cadence, suggesting consistent temporal resolution.
• Dataset includes specific 'Rules of the Road' governing data use and citation, promoting proper scientific attribution.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Data may reflect temporal and instrumental bias inherent to a single spacecraft mission.
