Cluster-Rumba WBD: High-Resolution Plasma Wave Data from Spacecraft

The Cluster-Rumba Wideband Data (WBD) provides calibrated high time resolution waveform data for electric and magnetic fields from four Cluster satellites. Data is sampled in three frequency bands up to 577 kHz, using antennas from the EFW instrument and magnetometers from the STAFF instrument. The dataset includes instrument mode, data quality, and orientation angles, with files available via the University of Iowa and ESA Cluster Science Archive.

Use Cases

• Analyze plasma wave propagation based on high-resolution electric and magnetic waveform data.
• Study wave mode identification based on data from three distinct filter bandwidth modes (9.5, 19, 77 kHz).
• Correlate wave activity with magnetic field orientation based on included GSE coordinate angles.
• Investigate frequency-shifted signals based on the capability to shift base frequency by 125.454, 250.908, or 501.816 kHz.

Strengths

• Data is collected from four distinct spacecraft (Rumba, Salsa, Samba, Tango), providing multi-point observations.
• Offers high time resolution, with sampling down to 4.6 microseconds in the 77 kHz bandwidth mode.
• Includes calibrated values for both electric and magnetic fields, along with instrument mode and data quality flags.

Limitations

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