Cassini RPWS LP: Electron Density and Spacecraft Potential from Saturn's Magnetosphere

NASA's Cassini mission provides electron densities derived from Langmuir Probe floating potential measurements throughout its entire Saturn mission. The data set includes spacecraft potential, floating potential, and electron density, intended to be the most complete record for Saturn's low-density outer magnetosphere. Data are presented in tables with fixed-length records for ease of handling.

Use Cases

• Model Saturn's magnetospheric plasma dynamics based on electron density measurements.
• Analyze spacecraft charging effects based on spacecraft potential data.
• Validate plasma instrument readings based on floating potential-derived electron densities.
• Study temporal variations in Saturn's outer magnetosphere based on mission-long coverage.

Strengths

• Data covers the entire Cassini mission at Saturn.
• Includes spacecraft potential, floating potential, and electron density.
• Data are presented in tables with fixed-length records for ease of handling.

Limitations

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