Ulysses Solar Wind Ion Composition Spectrometer (SWICS) Average Solar Wind Velocity, Isoto

3.5-hour averages of solar wind ion density ratios, velocity, and temperature from the Ulysses Solar Wind Ion Composition Spectrometer (SWICS). The dataset was created by Principal Investigators J. Geiss and G. Gloeckler, with a reference publication in Astronomy & Astrophysics Supplement Series in 1992. It is provided by the National Aeronautics and Space Administration.

Use Cases

• Modeling solar wind propagation based on average velocity data.
• Studying solar activity cycles based on isotope ratio trends.
• Analyzing coronal heating processes based on iron charge state measurements.

Strengths

• Data is aggregated into 3.5-hour averages, providing a consistent temporal resolution.
• Dataset is associated with a peer-reviewed reference publication (Astron. Astrophys. Suppl. Ser., 92(2), 267-289).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
