Helios 2 E7 (Trainor) Hourly Proton Flux Measurements

Hourly averaged proton fluxes from the GSFC Galactic and Solar Cosmic Ray experiment aboard the Helios 2 spacecraft. The data includes flux values and statistical errors for three distinct proton energy ranges: 3.3-21.6 MeV, 21.6-57 MeV, and above 57 MeV. This dataset is provided by the National Aeronautics and Space Administration and was last updated in March 2026.

Use Cases

• Modeling solar proton event propagation based on hourly flux measurements.
• Analyzing the relationship between proton energy spectra and solar activity based on the three defined energy ranges.
• Validating space weather forecasting models based on historical in-situ particle data.
• Studying the temporal evolution of galactic and solar cosmic rays based on the time-series structure.

Strengths

• Data includes statistical error estimates for each flux measurement.
• Proton fluxes are provided for three distinct and scientifically relevant energy ranges.
• Time is recorded with precision down to the second (year, month, day, hour, minute, second).

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 a BIN format, which may require specialized tools for access and parsing.
