VG2 NEP CRS: Voyager 2 Electron Counting Rates at Neptune

Voyager 2 data from the Cosmic Ray System's D1 detector during the Neptune encounter. The dataset describes the counting rate for electrons with kinetic energies above approximately 1 MeV. It was produced by the National Aeronautics and Space Administration and last updated in March 2026.

Use Cases

• Modeling the electron radiation environment near Neptune based on the described counting rates.
• Analyzing temporal variations in high-energy electron flux during a planetary encounter.
• Calibrating or validating space weather models for the outer solar system based on the detector's electron response.

Strengths

• Data originates from the NASA Voyager 2 mission, a primary source for outer solar system science.
• The description specifies the detector's nominal response to electrons above approximately 1 MeV.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
