PSP IS☉IS EPI-Hi: Parker Solar Probe Energetic Particle Rates, 1-Second Data

Parker Solar Probe (PSP) Integrated Science Investigation of the Sun (IS☉IS) Energetic Particle Instrument-Hi (EPI-Hi) merged rates data. This Level 2 dataset provides 1-second measurements of energetic particles, with calculations enabled by magnetic field data from the PSP FIELDS team. The data are provided by NASA and the IS☉IS Science Team, with the public dataset reflecting ongoing calibration efforts and last updated on 2026-03 13.

Use Cases

• Analyze solar energetic particle flux and intensity based on 1-second rate measurements.
• Study particle pitch angle distributions based on the description of magnetic field data integration.
• Model the near-Sun energetic particle environment based on calibrated instrument data.
• Investigate correlations between particle events and solar activity based on time-series data.

Strengths

• Data is calibrated by the IS☉IS science team, with updates planned based on improved instrument understanding.
• Pitch angle calculations are enabled by integration with magnetic field data from the PSP FIELDS instrument.
• Data is associated with a specific NASA mission (Parker Solar Probe) and a DOI for citation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and data volume are unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
