Voyager 2: Hourly Merged Magnetic Field and Plasma Data

Voyager 2 hourly merged magnetic field and plasma data was created at NSSDC for COHOWeb. Magnetic field vectors and plasma flow direction angles are given in RTN coordinates, while spacecraft position data are provided in Heliographic inertial (HGI) coordinates. The dataset was last updated on March 13, 2026.

Use Cases

• Analyzing solar wind plasma flow patterns based on plasma flow direction angles.
• Studying interplanetary magnetic field structure based on magnetic field vectors.
• Correlating spacecraft position with plasma and magnetic field measurements based on HGI coordinates.
• Modeling heliospheric phenomena based on merged hourly magnetic field and plasma data.

Strengths

• Data is merged from magnetic field and plasma instruments, providing correlated measurements.
• Coordinates are explicitly defined as RTN for vectors/angles and HGI for spacecraft position.
• Dataset is hosted by NASA, indicating institutional provenance.

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.
