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

High time resolution calibrated waveform data from the Wideband Data Plasma Wave Receivers on four Cluster satellites (Rumba, Salsa, Samba, Tango). The data includes electric and magnetic field measurements sampled in three frequency bands up to 577 kHz, along with instrument mode, data quality, and orientation angles. The dataset is produced by NASA and documented by the University of Iowa and the Cluster Science Archive.

Use Cases

• Analyze wave modes and frequencies in Earth's magnetosphere based on electric and magnetic field waveform data.
• Study wave propagation and polarization using the provided orientation angles relative to the magnetic field and GSE coordinate system.
• Investigate specific plasma wave phenomena (e.g., chorus, auroral kilometric radiation) using data from three distinct filter bandwidth modes.
• Compare plasma wave activity across different regions using simultaneous measurements from four distinct spacecraft.

Strengths

• Data is collected from four distinct spacecraft, providing multi-point observations.
• Offers high time resolution, with sampling intervals as low as 4.6 microseconds in the time domain.
• Includes calibrated electric and magnetic field values along with critical orientation metadata.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data availability depends on specific ground station telemetry downlink times.
• Row count is unknown, which may limit suitability assessment.
