PSP ISOIS EPI-Hi: Parker Solar Probe Energetic Particle Rates, 5-Minute Data

NASA's Parker Solar Probe Integrated Science Investigation of the Sun (ISOIS) instrument suite provides energetic particle data from the High Energy Telescope (HET). The Level 2 dataset contains 5-minute averaged rates, with pitch angle calculations enabled by magnetic field data from the PSP FIELDS team. Data calibration is ongoing and updates are released by the ISOIS Science Operations Center at the University of New Hampshire.

Use Cases

• Analyzing temporal evolution of high-energy particle fluxes near the Sun based on 5-minute rate data.
• Studying particle pitch angle distributions based on the integration of magnetic field data mentioned in the description.
• Modeling solar energetic particle events and their correlation with solar activity.
• Validating instrument response and calibration models for the near-Sun environment as described in the ongoing calibration efforts.

Strengths

• Data is from a current NASA flagship mission (Parker Solar Probe), with ongoing calibration updates.
• Includes pitch angle information derived from coordinated magnetic field measurements.
• Public data is managed by a dedicated Science Operations Center with a defined user guide and citation protocol.

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.
• Description metadata is limited; actual data quality requires manual inspection after download.
