PSP IS☉IS: Parker Solar Probe Energetic Particle Rates, 1-Minute Data

Parker Solar Probe (PSP) Integrated Science Investigation of the Sun (IS☉IS) instrument suite data. The dataset contains 1-minute rates from the Energetic Particle Instrument-Hi (EPI-Hi) Low Energy Telescope 1 (LET1), with epoch time tags indicating the midpoint of integration. The data is provided by the NASA Parker Solar Probe mission, with the IS☉IS team led by Princeton University, and was last updated in March 2026.

Use Cases

• Analyze solar energetic particle flux variations based on 1-minute rate data.
• Study particle pitch angle distributions based on magnetic field data integration mentioned in the description.
• Model the near-Sun energetic particle environment based on calibrated instrument response data.
• Correlate particle events with other Parker Solar Probe instrument measurements.

Strengths

• Data is calibrated by the IS☉IS science team, with ongoing calibration efforts noted.
• Includes pitch angle calculations enabled by magnetic field data from the PSP FIELDS team.
• Last updated on 2026-03-13, indicating recent maintenance.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The IS☉IS team notes that visualization tools and data are under continual development and cannot guarantee they are error-free.
• Row count and data volume are unknown, which may limit suitability assessment.
