Pioneer 11: Hourly Magnetic Field and Plasma Data

Hourly-resolution magnetic field vectors and plasma flow direction angles from the Pioneer 11 spacecraft, provided in RTN coordinates. The dataset was created by NASA's National Space Science Data Center (NSSDC) for the COHOWeb platform. Spacecraft position data are given in Heliographic inertial coordinates.

Use Cases

• Analyze solar wind plasma flow patterns based on plasma flow direction angles.
• Model magnetic field variations in the heliosphere based on magnetic field vectors.
• Correlate spacecraft position with plasma and magnetic field measurements based on Heliographic inertial coordinates.
• Study the structure of the solar wind based on merged magnetic field and plasma parameters.

Strengths

• Data is merged from magnetic field and plasma instruments, providing correlated measurements.
• Coordinates are explicitly defined (RTN and Heliographic inertial), aiding spatial analysis.
• Hourly resolution provides a consistent temporal scale for time-series analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
