In order to evaluate the impact of Asian dust to the air quality of North America, a relatively new type of factor analysis, positive matrix factorization (PMF), was applied to the particle composition data obtained at two high elevated sampling sites in the western United States, Crater Lake and Lassen Volcanic National Parks. This study indicated that PMF was a powerful factor analysis method to extract sources from the ambient aerosol concentration data.
