Voyager 2 Saturn Magnetic Field Measurements in Kronographic Coordinates, 1.92s Data

Voyager 2 Saturn encounter magnetometer data resampled to a 1.92-second rate from the original 60-millisecond instrument sampling. The dataset includes calibrated magnetic field vector components in Saturn-centered Kronographic (L1) coordinates, measured in nanotesla, and covers the period from the solar wind through at least the first magnetopause crossing. NASA produced this Level 4 processed dataset, with processing starting on 1988-09-21.

Use Cases

• Model Saturn's magnetospheric structure based on radial, azimuthal, and north/south magnetic field components.
• Analyze magnetic field dynamics during the spacecraft's transition from solar wind to magnetosphere based on the described coverage.
• Calculate derived parameters like magnetic latitude and longitude using the provided delta and lambda formulas.
• Assess measurement noise and variability using the provided RMS values for each field component.

Strengths

• Data is calibrated and processed to Level 4, indicating a high degree of refinement.
• Includes derived parameters like magnetic latitude (delta) and longitude (lambda) calculated from the raw components.
• Resampled from a high-resolution 60-millisecond instrument rate to a consistent 1.92-second sample rate.

Limitations

• Row count is unknown, which may limit suitability assessment.
• The maximum sampling parameter is listed as 'UNK' (unknown), indicating incomplete metadata on temporal coverage.
