PSP ISOIS EPI-Hi: Parker Solar Probe Energetic Particle Rates, 10-Second Data

Parker Solar Probe mission data from the Integrated Science Investigation of the Sun (ISOIS) instrument suite, specifically the High Energy Telescope (HET) rates. The dataset provides 10-second Level 2 measurements of energetic particles near the Sun, with calibration ongoing and updates planned over the mission's lifetime. The data is produced by the ISOIS science team led by Princeton University and funded by NASA.

Use Cases

• Analyzing temporal evolution of solar energetic particle fluxes based on 10-second rate data
• Correlating particle events with solar activity using time-tagged measurements
• Studying pitch angle distributions of particles using magnetic field data referenced in the description
• Validating and improving instrument calibration models for the near-Sun environment

Strengths

• Data originates from the NASA Parker Solar Probe, a primary source for near-Sun measurements
• Calibration is described as ongoing, with public updates planned, suggesting iterative quality improvement
• Includes pitch angle calculations enabled by magnetic field data from the PSP FIELDS team

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
• The description notes the team cannot guarantee the provided visualization tools are error-free
