Voyager 2 LECP: Jupiter Charged Particle Measurements

Voyager 2 spacecraft data from the Low Energy Charged Particle experiment during its Jupiter encounter. The dataset contains resampled, calibrated intensities of electrons (>13 keV) and ions (>24 keV) across eight angular sectors, averaged to 15-minute intervals. NASA produced this Version 1.1 dataset, which consolidates sector data into single records per channel.

Use Cases

• Analyzing angular anisotropy of charged particles based on data from eight rotating instrument sectors.
• Studying energy spectra of electrons and ions based on measurements from nearly 100 LECP channels.
• Calibrating particle intensity measurements based on background subtraction using Sector 8 (sunshield-covered) data.
• Investigating temporal variations in Jupiter's particle environment based on 15-minute averaged time-series data.

Strengths

• Data is globally calibrated, as stated in the description.
• Version 1.1 consolidates nine repeated times per channel into single records, improving structure.
• Full angular anisotropy information is preserved due to rotation cycles faster than 15 minutes.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Conversion from 'Rate' to 'Intensity' depends on uncertain determinations of mass species and background levels.
