Abstract: On the basis of simulations of emissions and surface concentrations for Asian dust along with validations from a network observation, the anthropogenic related desertification areas within China contribute only about 6% increasing to Asian dust storm. This idea is also derived from the re-assessment of sensitivity test for dust concentration reduction by removing the desertification areas, and simulated dust emission fractions from different Asian dust sources.

Key words: Asian dust sources, dust storm formation, contribution of desertification to dust storm
