VG1 LECP: Voyager 1 Jupiter Far Encounter Charged Particle Flux Data

Voyager 1 Low Energy Charged Particle (LECP) experiment data provides 3.2-minute counting rate and flux measurements for electrons and ions during the spacecraft's far encounter with Jupiter. The instrument measured intensities of in-situ charged particles (>15 keV electrons and >30 keV ions) across almost 100 channels, including electrons, protons, alpha particles, and nuclei. The data are globally calibrated to the extent possible and were collected by NASA.

Use Cases

• Analyzing charged particle flux variations based on 3.2-minute time-series measurements
• Studying Jupiter's magnetospheric particle populations based on species discrimination (electrons, protons, alpha particles, nuclei)
• Modeling spacecraft instrument response based on globally calibrated data from the LECP experiment

Strengths

• Data includes almost 100 distinct LECP measurement channels
• Measurements are globally calibrated to the extent possible
• Provides 3.2-minute resolution flux data during a specific mission phase

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
