Ulysses COSPIN-LET: 10-Minute Average Cosmic Ray and Solar Particle Fluxes

10-minute average fluxes of protons, alpha particles, and heavier nuclei (Lithium, Beryllium, Boron, Carbon, Nitrogen, Oxygen, Z≥10) across multiple energy ranges, along with eight-sectored proton fluxes and electron count rates. The data was collected by the Ulysses spacecraft's COSPIN-LET instrument and is provided by the National Aeronautics and Space Administration. The dataset was last updated on 2026-03-13.

Use Cases

• Modeling solar particle event propagation based on multi-energy proton and alpha particle fluxes.
• Analyzing galactic cosmic ray composition based on fluxes of Lithium, Beryllium, Boron, Carbon, Nitrogen, and Oxygen nuclei.
• Studying particle anisotropy in the heliosphere based on eight-sectored proton flux data.
• Correlating electron count rates with other particle populations for event identification.

Strengths

• Includes fluxes for multiple particle species (protons, alphas, heavier nuclei) across defined energy channels.
• Provides directional information via eight-sectored proton fluxes for two energy ranges.
• Data is averaged at a 10-minute resolution, suitable for time-series analysis of dynamic events.

Limitations

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