Dust emissions significantly impact the radiation balance, ecosystems, human health, and global climate change through long-range transport. However, their spatiotemporal characteristics driving mechanisms in East Asia remain poorly understood. This study integrates multi-source reanalysis remote sensing data (1980–2023) to analyze dust across Asian source regions using statistical methods SHapley Additive exPlanations (SHAP) interpretability. The results show significant spatial seasonal variations, with peak occurring spring (March–May). Taklamakan Desert (S4) accounts for 38.1% of total is largest region. Meteorological factors are main drivers (49.4–68.8% contribution), while indices contribute least (2.9–8.0%).
