ICON IVM: Ion Velocity Measurements from Satellite Sensors

ICON Ion Velocity Meter (IVM) data originates from NASA. The IVM instrument consists of two planar thermal ion sensors, a retarding potential analyzer (RPA) and an ion drift meter (IDM). The dataset was last updated on March 13, 2026.

Use Cases

• Modeling ionospheric plasma drifts based on ion drift meter (IDM) measurements.
• Analyzing ion temperature and composition based on retarding potential analyzer (RPA) data.
• Studying space weather effects on satellite orbits using thermal ion sensor readings.
• Validating atmospheric models with in-situ ion velocity measurements.

Strengths

• Data originates from the authoritative source NASA.
• Last updated on March 13, 2026, indicating recent maintenance.

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.
