VG1 LECP: Voyager 1 Charged Particle Measurements Near Jupiter

Voyager 1's Low Energy Charged Particle experiment recorded electron and ion intensities during its close encounter with Jupiter. The instrument measured in-situ charged particles with energies above 15 keV for electrons and above 30 keV for ions, including protons, alpha particles, and heavier nuclei. This dataset from the National Aeronautics and Space Administration was last updated in April 2026.

Use Cases

• Modeling Jupiter's magnetospheric dynamics based on in-situ charged particle measurements.
• Analyzing energy spectra of electrons and ions based on the described energy ranges (>15 keV electrons, >30 keV ions).
• Studying the composition of charged particle populations near Jupiter based on discrimination by mass species (protons, alpha particles, Z >= nuclei).
• Calibrating or validating space weather models based on globally calibrated LECP data.

Strengths

• Data is described as 'globally calibrated to the extent possible'.
• Provides measurements from the Voyager 1 spacecraft's 'very close vicinity' of Jupiter, a key planetary encounter.

Limitations

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