Cluster-Rumba WBD: High-Resolution Plasma Wave Data from Four Satellites

High time resolution calibrated waveform data from the four Cluster satellites (Rumba, Salsa, Samba, Tango) in the 0-577 kHz frequency range. The data includes electric and magnetic field measurements from specific instruments, sampled at resolutions as high as 4.6 microseconds. It is produced by NASA and maintained by the University of Iowa, with documentation available through the Cluster Science Archive.

Use Cases

• Analyze plasma wave propagation and mode identification based on high-resolution electric and magnetic field waveforms.
• Study specific wave phenomena like chorus or hiss based on the listed platform tags (e.g., Chorus, Auroral Hiss, Plasmaspheric Hiss).
• Correlate wave activity with spacecraft orientation using the included magnetic field and GSE coordinate system angles.
• Investigate instrument performance and data quality across different filter bandwidth modes (9.5, 19, 77 kHz).

Strengths

• Data is collected from four distinct spacecraft, providing multi-point measurements for spatial analysis.
• Offers very high temporal resolution, with sampling as fast as 4.6 microseconds in the time domain.
• Includes calibrated values for both electric and magnetic fields, along with instrument mode and data quality flags.

Limitations

• Data availability depends on specific ground station telemetry downlinks, which may create gaps.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total dataset size are unknown, which may limit suitability assessment.
