Short summary

PlanetGSD 1.0, the first standardized cross-planetary grain-size database, provides 6,527 harmonized measurements (Earth, Moon, Mars) via the Unified Grain Size Distribution (UGSD) function. Openly available at Figshare, it enables robust regolith comparison, simulant benchmarking, and landing site assessment.
