PlanetGSD 1.0: Grain-Size Distribution Data for Earth, Moon, and Mars

PlanetGSD 1.0 is a cross-planetary grain-size distribution dataset containing separate tables for Terrestrial, Lunar, and Martian soils. The dataset includes 3.7 MB of data in TXT and XLSX formats, authored by Jun Zhang and last updated on 2026-05-22. It also provides site descriptions, image references for Martian soils, and statistical simulation and fitting code.

Use Cases

• Comparative analysis of soil properties based on grain-size distribution data from three planetary bodies.
• Statistical modeling of soil behavior using the provided simulation code based on statistical distribution.
• Parameter fitting for granular materials using the Weibull distribution fitting code for UGSD parameters.
• Correlating soil characteristics with surface processes using the site descriptions and dominant process data.

Strengths

• Provides data from three distinct planetary environments: Earth, the Moon, and Mars.
• Includes 3.7 MB of structured data files in TXT and XLSX formats.
• Supplements tabular data with simulation and fitting code for statistical analysis.

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 modeling.
• Description metadata is limited; actual data quality requires manual inspection after download.
