ISEE-3: High-Resolution Magnetic Field Data from a NASA Satellite

ISEE-3 provides the highest-time-resolution magnetic field measurements available from its onboard instrument. NASA organized the data into four compressed ASCII files per day, stored in yearly sub-directories, though files may be absent for days with no data. The dataset was last updated on March 13, 2026.

Use Cases

• Analyze solar wind dynamics based on high-resolution magnetic field time series.
• Model magnetospheric disturbances based on continuous satellite measurements.
• Validate space weather simulation outputs based on empirical magnetic field data.
• Study temporal variations in the interplanetary magnetic field based on daily data segments.

Strengths

• Data is described as the highest-time-resolution magnetic field data available from the ISEE-3 mission.
• Files are organized into four segments per day, suggesting a consistent temporal structure.
• Source organization is the authoritative National Aeronautics and Space Administration (NASA).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Some or all files for a particular day may be absent, indicating potential data gaps.
• Row count and total data volume are unknown, which may limit suitability assessment.
