VG2 JUP PLASMA: Voyager 2 Electron Density and Temperature at Jupiter

Derived electron density and temperature measurements from the Voyager 2 spacecraft encounter with Jupiter. The data set contains moment calculations from composite electron spectra in the PLS voltage range (10-5950 eV/q), assuming isotropic distributions and correcting for spacecraft charge. It was produced by the National Aeronautics and Space Administration and last updated in March 2026.

Use Cases

• Modeling Jupiter's magnetospheric plasma environment based on derived electron density and temperature.
• Analyzing temporal variations in plasma parameters during the Voyager 2 flyby based on timestamped measurements.
• Calibrating or validating space physics simulations using in-situ electron moment data.
• Studying spacecraft charging effects in planetary environments based on the described correction techniques.

Strengths

• Data includes explicit handling for spacecraft charge correction and interpolation below instrument thresholds.
• Missing data is clearly flagged with a specific value (-9.99e+10).
• Produced by the authoritative source National Aeronautics and Space Administration.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect temporal bias inherent to the single Voyager 2 encounter.
