ISIS 2 Plasma Data: Ion Densities and Space Environment Indices

Ion densities for species from 1 to 64 atomic mass units, including H+, D+, He+, N++, O++, N+, O2+, and others, measured by the ISIS 2 satellite's ion-mass spectrometer. The dataset also includes spacecraft position, geomagnetic field intensity, and solar/geomagnetic activity indices (F107, Kp, Dst). It is provided by the National Aeronautics and Space Administration and was last updated in March 2026.

Use Cases

• Modeling ionospheric composition based on measured ion densities of H+, D+, He+, N++, O++, and heavier ions.
• Correlating plasma conditions with solar activity using the included daily solar radio flux (F107) data.
• Studying geomagnetic storm effects on the ionosphere using the provided Kp and Dst indices.
• Analyzing spatial variations in plasma by combining ion density data with spacecraft position information.

Strengths

• Includes measurements for a specific range of ion species (1-64 atomic mass units).
• Integrates core space physics variables: ion densities, spacecraft position, geomagnetic field, and solar/geomagnetic indices.
• Provided by the authoritative source National Aeronautics and Space Administration.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is stored in BIN and HTML formats, which may require specialized tools for access and parsing.
