Kaguya Lunar Spectra of Small Fresh Craters

KAGUYA LUNAR SP DERIVED SPECTRA V1.0 is a survey of spectra from small, fresh lunar craters observed by the JAXA Kaguya Spectral Profiler. It provides crater latitude, longitude, FeO and OMAT values, and estimated mineralogical composition for each spectral observation. The dataset is produced by the National Aeronautics and Space Administration and was last updated in August 2025.

Use Cases

• Map FeO and OMAT values across crater locations to study lunar surface composition variations.
• Analyze the correlation between estimated mineralogical composition and crater geographic coordinates.
• Use crater latitude and longitude data to spatially reference spectral observations for regional geological studies.

Strengths

• Focuses on small, fresh lunar craters (< 1 km), a specific geological feature.
• Includes derived geochemical parameters like FeO and OMAT values for each observation.
• Data originates from the JAXA Kaguya Spectral Profiler instrument, a primary lunar mission.

Limitations

• The dataset's total number of spectral observations (rows) is unknown, limiting assessment of statistical power.
• The specific spectral wavelengths and number of derived features (columns) are not detailed.
• Derived mineralogical compositions are estimates, which may contain modeling uncertainties.
