Voyager 2 Plasma Data: Daily Averages from Faraday-Cup Detectors

Daily averages of plasma data collected by the Voyager 2 spacecraft. The data originates from two Faraday-cup detectors measuring ion velocity, density, and pressure, and electron energy from 5eV to 1 keV. The dataset is provided by the National Aeronautics and Space Administration and was last updated in March 2026.

Use Cases

• Modeling solar wind properties based on measured ion velocity and density.
• Analyzing plasma flow regimes from subsonic to supersonic based on the described energy scan methodology.
• Studying electron energy distributions based on the side-looking Faraday cup's 5eV to 1 keV measurements.
• Investigating long-term trends in interstellar plasma based on daily-averaged time-series data.

Strengths

• Data originates from the authoritative Voyager 2 mission by the National Aeronautics and Space Administration.
• Description specifies measurement of ion velocity, density, and pressure, and electron energy from 5eV to 1 keV.
• Last updated on 2026-03-13, suggesting recent metadata maintenance.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• The license is listed as 'other-license-specified', requiring careful review before use.
