Voyager 1 Plasma Ion Composition Near Jupiter, 96 s Data

Voyager 1 Plasma Spectrometer data reanalyzed by the University of Colorado's LASP group provides plasma ion composition near Jupiter. Density, temperature, and flow velocity fits for total and individual ions are derived from processing ion currents from four instrument cups. The VIPER-Fit code applies five different constraints for each 96-second interval, including fixed composition and interpolation between plasma torus regions.

Use Cases

• Modeling Jupiter's plasma torus dynamics based on ion density and temperature fits
• Analyzing ion species abundance variations based on O+, O++, S+, S++, S+++ composition constraints
• Studying plasma flow velocity changes near Jupiter based on 96-second interval measurements
• Comparing plasma conditions in cold torus and plasmasheet regions based on different VIPER-Fit constraints

Strengths

• Data originates from the Voyager 1 mission, a primary source for Jupiter exploration
• Reanalysis performed by the Laboratory for Atmospheric and Space Physics (LASP) at the University of Colorado
• Fits include density, temperature, and flow velocity for total and five individual ion species

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data is stored in BIN and PDF formats, which may require specialized tools for access
