PEPSSI: Hourly Averaged Plasma Fluxes from New Horizons, 2012-2020

From early 2012 through late 2020, this dataset provides one-hour averaged energetic particle flux rates and counts-per-second from the Pluto Energetic Particle Spectrometer Science Investigation (PEPSSI) instrument on the New Horizons spacecraft. It was generated by the New Horizons Particles and Plasma science team and presents flux rates and sums for each of the instrument's six look directions.

Use Cases

• Analyze temporal trends in energetic particle fluxes based on the one-hour averaged values.
• Compare particle flux rates across different spatial orientations based on the six instrument look directions.
• Model plasma behavior in the outer solar system based on the PEPSSI instrument measurements.
• Validate spacecraft instrument performance based on the long-term data coverage from 2012 to 2020.

Strengths

• Data covers a long time range from early 2012 through late 2020.
• Flux rates are provided for six distinct instrument look directions.
• Data is averaged to one-hour intervals, likely providing a stable basis for analysis.

Limitations

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