PSP IS☉IS EPI-Hi: High-Energy Solar Particle Rates, 1-Hour Data

Parker Solar Probe IS☉IS EPI-Hi instrument data provides high-energy telescope rates for energetic particles near the Sun. The dataset is funded by NASA and maintained by the University of New Hampshire Science Operations Center, with calibration updates ongoing throughout the mission. Data includes pitch angle calculations derived from magnetic field measurements by the PSP FIELDS team.

Use Cases

• Modeling solar energetic particle acceleration and transport based on high-energy telescope rates.
• Analyzing pitch angle distributions of particles based on magnetic field data integration.
• Studying temporal evolution of near-Sun particle populations based on 1-hour integrated data.
• Validating instrument response and calibration models for the EPI-Hi detector.

Strengths

• Data originates from the NASA Parker Solar Probe mission, a primary source for near-Sun measurements.
• Calibration is described as ongoing, with public data updates planned based on improved instrument understanding.
• Includes pitch angle calculations enabled by integration with magnetic field data from another instrument team.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The description notes the IS☉IS team cannot guarantee the provided visualization tools are error-free.
