ARMAS Radiation Dose Rates from ATom-1 Flight Campaign

Global flight paths from the ATom-1 campaign in July-August 2016 provide absorbed and equivalent radiation dose rates. The NASA ARMAS system measured dose rates in silicon from galactic cosmic rays, solar energetic particles, and Van Allen belt particles. This data supports analysis of radiation effects on atmospheric chemistry, human tissue, and aerospace electronics.

Use Cases

• Modeling atmospheric chemistry by correlating radiation dose rates with chemical species data from the ATom campaign.
• Assessing radiation exposure risks to aviation crew and passengers using the provided ambient equivalent dose rates.
• Validating satellite-based radiation belt models with in-situ airborne measurements across global flight paths.
• Analyzing the spatial distribution of galactic cosmic ray intensity at aviation altitudes.

Strengths

• Data originates from a NASA instrument (ARMAS) on a dedicated atmospheric science campaign (ATom).
• Provides both absorbed dose in silicon and biologically weighted ambient equivalent dose rates for human health analysis.
• Covers a specific, well-documented time period (July-August 2016) with global spatial coverage from flight paths.

Limitations

• Core data dimensions (row count, column names, file size) are unspecified across all platforms.
• Conflicting last update dates exist: Data.gov lists 2026-03 13, while NASA Earthdata lists 2016-08-23.
