Voyager 2 LECP Jupiter Far Encounter Charged Particle Rates

Almost 100 channels of electron and ion counting rate data from the Voyager 2 Low Energy Charged Particle experiment during its Jupiter far encounter. The National Aeronautics and Space Administration collected these 0.4-second high-resolution measurements of particles above 13 keV electrons and 24 keV ions. The data includes particles such as electrons, protons, alpha particles, and light, medium, and heavy nuclei.

Use Cases

• Analyze charged particle anisotropies based on the rotating head and eight angular sectors
• Study particle species distributions based on the discrimination by energy range and mass species
• Model Jupiter's magnetospheric environment based on in-situ electron and ion intensity measurements
• Calibrate sensor data based on the use of Sector 8 rates covered by an aluminum sunshield

Strengths

• Almost 100 LECP channels provide multi-dimensional particle measurements
• High temporal resolution of 0.4-second rate measurements during the encounter
• Includes globally calibrated data with documented geometric factors and energy bandpasses

Limitations

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