Voyager 2 VIPER-Fit Plasma Ion Composition near Jupiter

Voyager 2 Plasma Spectrometer (PLS) VIPER-Fit Plasma Ion Composition near Jupiter, 96 s Data contains re-analysis results from the Voyager Plasma Spectrometer at Jupiter. The Laboratory for Atmospheric and Space Physics (LASP) at the University of Colorado processed ion currents to produce density, temperature, and flow velocity fits for total and individual ions using the VIPER code. Fits were generated under five different constraint cases for each 96-second time interval.

Use Cases

• Modeling plasma density and temperature variations near Jupiter based on the VIPER-fit parameters.
• Analyzing ion composition and flow velocity changes in the Io plasma torus based on the described constraint cases.
• Comparing plasma properties between different regions (cold ion torus, plasmasheet) based on the fit case variable.
• Validating theoretical plasma models using the re-analyzed Voyager 2 spectrometer data.

Strengths

• Data originates from the Voyager 2 mission, a primary source for Jupiter's plasma environment.
• Analysis uses the VIPER code with five specific constraint cases for each 96-second interval, providing methodological detail.
• Fits include parameters for total and individual ions (O+, O++, S+, S++, S+++).

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 and analysis.
