Helios 1 E7: Hourly Proton Flux Data for Three Energy Ranges

NASA's Helios 1 E7 dataset contains hourly averaged fluxes of protons measured by the GSFC Galactic and Solar Cosmic Ray experiment. Each record includes date, time, and flux values with statistical errors for proton energy ranges of 3.3-21.6 MeV, 21.6-57 MeV, and above 57 MeV. The data was last updated on 2026-03-13.

Use Cases

• Modeling solar proton event time profiles based on hourly averaged flux data.
• Analyzing the energy spectrum of solar cosmic rays based on the three specified proton energy ranges.
• Studying statistical uncertainties in particle flux measurements based on the included error values.
• Correlating proton flux variations with solar activity based on the time-series structure.

Strengths

• Data originates from a NASA satellite mission (Helios 1) and a specific experiment (GSFC Galactic and Solar Cosmic Ray).
• Includes statistical errors for the flux measurements, which is critical for analysis.
• Covers three distinct proton energy ranges (3.3-21.6 MeV, 21.6-57 MeV, >57 MeV).

Limitations

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