ISEE 3: Cosmic Ray Elemental Abundance Ratios from 1978-1981

An ASCII file contains 25 abundance ratios for pairs of chemical elements derived from cosmic ray observations. The ratios are based on data from the University of Chicago experiment on the ISEE 3 satellite, collected between 1978 and 1981 for particles with energies of approximately 50-500 MeV/n. Each ratio is linked to its source publication within the file.

Use Cases

• Modeling galactic chemical evolution based on cosmic ray elemental abundance ratios.
• Comparing solar system and cosmic ray composition based on the 25 provided abundance ratios.
• Calibrating or validating cosmic ray propagation simulations using the published, cited ratios.

Strengths

• Provides 25 specific abundance ratios with associated uncertainties.
• Each ratio is linked to its source publication, facilitating verification and deeper study.
• Data originates from a specific, documented space mission (ISEE 3) and experiment (U. Chicago).

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 statistical modeling.
• Data is from a specific time period (1978-1981) and may not reflect more recent observations.
