PSP IS☉IS EPI-Hi LET2: Hourly Energetic Particle Rates from Parker Solar Probe

Parker Solar Probe (PSP) data from the Integrated Science Investigation of the Sun (IS☉IS) instrument suite, specifically the Energetic Particle Instrument-Hi (EPI-Hi) Low Energy Telescope 2 (LET2). The data provides hourly (1 h) rates of energetic particles, with epoch time tags indicating the midpoint of integration. The dataset is produced by the IS☉IS science team, led by Princeton University, and is funded by NASA under contract NNN06AA01C.

Use Cases

• Modeling solar energetic particle fluxes based on hourly rate data.
• Analyzing temporal variations in particle populations near the Sun.
• Correlating particle events with solar activity using the provided time tags.
• Studying pitch angle distributions by combining with magnetic field data from the PSP FIELDS team.

Strengths

• Data is from a current NASA flagship mission (Parker Solar Probe) with ongoing calibration.
• Includes pitch angle calculations enabled by integration with magnetic field data.
• Public data reflects current instrument calibration as determined by the science team.

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.
