Voyager 2 LECP: Uranus Charged Particle Intensities at 15-Minute Resolution

A subset of nearly 100 channels from the Low Energy Charged Particle (LECP) instrument on Voyager 2 provides resampled intensities of electrons (>26 keV) and ions (>30 keV) near Uranus. The data are time-averaged to approximately 15-minute intervals, matching the instrument's angular scanning cycle periods. This dataset was produced by NASA and includes globally calibrated, scan-averaged measurements.

Use Cases

• Analyzing temporal variations in charged particle fluxes near Uranus based on 15-minute averaged intensities.
• Studying the energetic particle environment of Uranus's magnetosphere based on electron and ion channel data.
• Calibrating instrument rates to physical intensities using provided geometric factors and energy bandpass parameters.
• Investigating background contamination in particle measurements using data from the shielded calibration sector.

Strengths

• Includes nearly 100 specific instrument channels for detailed particle analysis.
• Data are globally calibrated to the extent possible, providing a standardized baseline.
• Time intervals are aligned with the instrument's physical scanning cycles, preserving temporal context.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data are scan-averaged; no angular anisotropy information is included.
