DMC-China: 541,074 Dust Particles from China's Source Regions

541,074 individual dust particles generated from 55 soil samples collected across major dust source regions in China, including the Taklimakan Desert, Gobi Desert, Hunshandake Sandy Land, and Qinghai–Tibet Plateau. The dataset was created by Long Zhang and published on figshare in May 2026. It contains morphology and composition data analyzed via energy-dispersive X-ray spectroscopy.

Use Cases

• Analyze dust particle morphology and composition based on CCSEM-EDX spectroscopy data
• Compare mineral classification results based on the two different classification methods provided
• Study the geographic distribution of dust properties based on the 55 sample site locations
• Model dust emission and transport processes based on particle characteristics from specific source regions

Strengths

• Contains 541,074 individual dust particle records
• Sourced from 55 distinct soil samples across four major Chinese regions
• Provides two different mineral classification rule sets for comparison

Limitations

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