Ulysses COSPIN/KET: Daily Proton, Helium, and Electron Fluxes

Daily average fluxes of protons, alpha particles, and electrons across multiple energy channels, measured by the COSPIN/KET instrument on the Ulysses spacecraft. The data includes Poisson uncertainties for each flux measurement. The dataset is provided by the National Aeronautics and Space Administration.

Use Cases

• Analyze solar particle event intensity based on proton flux measurements across four energy ranges
• Study galactic cosmic ray composition based on helium (alpha particle) fluxes in four energy/nucleon channels
• Investigate electron flux variations in the 2.5-7.0 MeV and 2.5 GV ranges
• Calculate statistical uncertainties for particle flux analyses based on the included Poisson uncertainties

Strengths

• Fluxes are provided for protons, helium, and electrons across multiple specific energy ranges
• Includes Poisson uncertainties for each flux measurement, enabling statistical analysis

Limitations

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