VG2 LECP: Voyager 2 Charged Particle Measurements at Neptune

12.8-minute resolution particle flux data collected by the Voyager 2 spacecraft's Low Energy Charged Particle (LECP) instrument during its far encounter with Neptune. The dataset includes counting rates and fluxes for electrons, protons, alpha particles, and various nuclei from almost 100 instrument channels. It was produced by the National Aeronautics and Space Administration (NASA) and last updated in March 2026.

Use Cases

• Analyzing charged particle flux variations based on 12.8-minute step measurements.
• Studying the composition of planetary magnetospheres based on data for electrons, protons, alpha particles, and nuclei.
• Modeling the low-energy particle environment of Neptune based on calibrated LECP instrument data.
• Investigating particle dynamics during spacecraft encounters based on data from the LEPT and LEMPA subsystems.

Strengths

• Data is globally calibrated to the extent possible, as stated in the description.
• Includes measurements from almost 100 distinct LECP instrument channels.
• Covers multiple particle species: electrons, protons, alpha particles, and light, medium, and heavy nuclei.

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.
