Voyager 1 Jupiter Charged Particle Measurements, 15-Minute Intervals

Resampled data from the Low Energy Charged Particle experiment on Voyager 1 during its Jupiter encounter. The dataset consists of calibrated, sectored measurements of >26 keV electrons and >30 keV ions averaged to 15-minute intervals. It was produced by NASA and archived with the Planetary Data System.

Use Cases

• Analyzing charged particle anisotropy based on eight angular sector measurements.
• Studying particle energy spectra near Jupiter based on nearly 100 LECP channels.
• Calibrating instrument rates to physical intensities using provided geometric factors.
• Investigating temporal variations in the Jovian environment using 15-minute averaged data.

Strengths

• Data is globally calibrated and resampled to preserve full angular anisotropy information.
• Version 1.1 consolidates data for a given channel and time period into a single record.
• Includes nearly 100 LECP channels measuring electrons and ions across different energy ranges.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data are in 'Rate' form, requiring conversion to physical units based on contextual analysis.
