OMNI 1-min Data Set: Near-Earth Solar Wind and Geomagnetic Indices

High-resolution 1-minute solar wind and geomagnetic data from NASA, shifted to Earth's bow shock nose. The dataset combines multi-source magnetic field and plasma measurements with geomagnetic activity indices. It was last updated on March 13, 2026.

Use Cases

• Forecasting geomagnetic storms based on 1-minute solar wind parameters
• Correlating plasma data with geomagnetic activity indices for event analysis
• Modeling magnetospheric response using high-resolution time-series data
• Validating space weather models with multi-source, near-Earth observations

Strengths

• Data resolution is 1-minute, enabling fine-grained temporal analysis
• Combines multiple data sources including magnetic field, plasma, and activity indices
• Published by the authoritative organization National Aeronautics and Space Administration (NASA)
• Data is processed and shifted to a consistent reference point at Earth's bow shock nose

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
