VG2 JUP PLS DERIVED ION IN/OUTBNDMAGSHTH L-MODE 96SEC V1.0

Voyager 2 plasma data from Jupiter's magnetosheath, magnetotail, and solar wind, sampled near noon local time. Derived proton velocity, density, and temperature using a two-component Maxwellian model to represent thermal and reflected ion populations. The National Aeronautics and Space Administration provides this dataset with one-sigma errors for the fit parameters.

Use Cases

• Modeling plasma flow dynamics in Jupiter's magnetosheath based on the described subsonic flow region.
• Analyzing two-component proton populations (thermal and reflected) based on the derived Maxwellian parameters.
• Studying shock acceleration processes at planetary boundaries based on the described ion populations.
• Validating magnetospheric simulation outputs using in-situ plasma measurements from the Voyager 2 mission.

Strengths

• Data includes one-sigma errors for the derived fit parameters, providing uncertainty estimates.
• Derived parameters are based on a specific physical model (two convected isotropic proton Maxwellians) described in the documentation.
• Data covers multiple regions: inbound magnetosheath, outbound magnetotail, and solar wind.

Limitations

• The PLS experiment could not resolve alpha particles, which may cause an overestimate of the hot proton component.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file formats are unknown, which may limit suitability assessment.
