Ulysses COSPIN-LET: Oxygen, Nitrogen, and Neon Fluxes, 20-Day Average

NASA's Ulysses COSPIN-LET dataset provides 20-day average fluxes of energetic particles. It contains pulse-height-analysis-based fluxes for Oxygen, Nitrogen, and Neon across multiple energy ranges per nucleon, along with Poisson uncertainties. The data was last updated on March 13, 2026.

Use Cases

• Analyze solar particle event intensity based on Oxygen flux in the 4-8 MeV/n range.
• Study galactic cosmic ray composition based on Nitrogen flux in the 8-20 MeV/n range.
• Model particle acceleration processes based on Neon flux in the 9-30 MeV/n range.
• Assess statistical uncertainty in particle measurements based on provided Poisson uncertainties.
• Investigate long-term trends in energetic particle populations based on 20-day averaged data.

Strengths

• Fluxes are provided for three distinct particle species: Oxygen, Nitrogen, and Neon.
• Data includes multiple energy ranges per nucleon for each species.
• Poisson uncertainties are included for each flux measurement.
• Data is averaged over 20-day intervals, likely smoothing short-term variability.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The data format is BIN, which may require specialized tools for access.
