Ulysses Magnetic Field: One-Hour Interplanetary Measurements

High-resolution one-hour samples of the interplanetary magnetic field measured by the Ulysses spacecraft. Vector components are provided in RTN coordinates with magnitudes averaged from higher-resolution readings. The data is organized into daily files and excludes measurements from the February 1992 Jupiter encounter.

Use Cases

• Modeling solar wind interactions based on magnetic field vector components.
• Analyzing temporal trends in interplanetary magnetic field strength based on hourly averages.
• Studying the structure of the heliosphere using RTN coordinate system data.

Strengths

• Data is sampled at high resolution at approximately one-hour intervals.
• Field vector components are provided in a defined RTN coordinate system.
• Data is organized into daily files for convenient temporal segmentation.

Limitations

• Data gaps are not flagged; missing hours result in absent records.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
