Cluster-Rumba EDI: Electron Drift and Electric Field Measurements from ESA Cluster Mission

The European Space Agency's Cluster spacecraft Electron Drift Instrument (EDI) data products. The dataset includes time series of electron drift velocity and electric field components in GSE coordinates, ambient electron counts at fixed energies, and overview plots. Data was produced by the National Aeronautics and Space Administration and last updated in March 2026.

Use Cases

• Analyzing electron drift velocity in the solar wind based on the three-component time series.
• Studying electric field dynamics in the magnetosphere based on corrected GSE coordinate measurements.
• Investigating ambient electron pitch angle distributions based on 16 ms resolution count data.
• Validating plasma physics models using the overview plots generated every 3 hours.

Strengths

• Includes three distinct data product categories with specific measurement modes described.
• Provides high-resolution time series data at 16 ms for ambient electron counts.
• Data is corrected for spacecraft motion in the GSE coordinate system.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
