ICON IVM-B: Ion Velocity Measurements from Satellite Sensors

ICON Ion Velocity Meter (IVM) B data provides measurements from two planar thermal ion sensors, a retarding potential analyzer (RPA), and an ion drift meter (IDM). The dataset is produced by the National Aeronautics and Space Administration (NASA) and was last updated on March 13, 2026. The data is stored in BIN and HTML file formats.

Use Cases

• Analyze ion temperature and composition based on retarding potential analyzer (RPA) measurements
• Model ion drift velocities and electric fields based on ion drift meter (IDM) data
• Study thermal ion distribution and plasma dynamics based on planar sensor outputs
• Validate and calibrate space weather models using in-situ ionospheric measurements

Strengths

• Data originates from the authoritative National Aeronautics and Space Administration (NASA)
• Last updated on 2026-03-13, indicating recent maintenance
• Includes measurements from multiple specialized instruments (RPA and IDM)

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
