The aerosol concentration and composition were measured to investigate the 5 regional characteristics of spring Asian dust and its impact on aerosol chemistry over Regional northern China. Based on the daily PM10 concentrations in 13 cities, the northern characteristics of China could be divided into five regions, i.e., Northern Dust Region, Northeastern Dust spring Asian dust Region, Western Dust Region, Inland Passing Region, and Coastal Region.
