VG2 LECP: Voyager 1 Saturn Near Encounter Charged Particle Data

Voyager 1's Low Energy Charged Particle experiment collected this data during the spacecraft's close approach to Saturn. The dataset includes 0.4-second measurements of electron and ion counting rates from almost 100 instrument channels, covering particles like protons, alpha particles, and nuclei. NASA produced this calibrated dataset, last updated on March 13, 2026.

Use Cases

• Analyze Saturn's magnetospheric particle composition based on the described electron, proton, alpha particle, and ion measurements.
• Model charged particle intensity variations over time based on the 0.4-second high-resolution rate data.
• Study the angular scanning behavior of the LECP instrument during the near encounter period.
• Compare low-energy and high-energy particle populations based on the described energy range discrimination.

Strengths

• Data is globally calibrated to the extent possible, as stated in the description.
• Includes measurements from almost 100 LECP channels.
• Provides high-resolution 0.4-second rate measurements during the Saturn encounter.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
