Delbo Thermal Infrared Asteroid Diameters and Albedos V1.0

NASA's dataset contains radiometric albedos and diameters for Near Earth Asteroids derived from thermal models. The data is based on observed infrared fluxes and was reported in the 2004 Delbo publication. The dataset was last updated on March 13, -2026.

Use Cases

• Modeling asteroid thermal properties based on reported infrared fluxes.
• Comparing asteroid diameters derived from different thermal models.
• Analyzing radiometric albedos for Near Earth Asteroids.
• Validating thermal model outputs against observational flux data.

Strengths

• Data originates from the authoritative source NASA.
• Includes results derived from three different thermal models for comparison.
• Contains the underlying observed infrared flux data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
