| Abstract: | On the basis of the data of concentrations as well as wind and temperature, simultaneously observed in the north suburb of Beijing, measurements have been made of the dry deposition velocities of suspended particles. Results show that, over such an environment, the dry deposition velocities for suspended par-ticles vary from 0.15 to 10.62 cm s-1, which are comparable with those over forests, that the average surface resistance in the transfer process of particles is about four times as large as the aerodynamic resis-tance, and that the dry deposition velocity is well related to the frictional velocity in terms of positive cor-relation function. |
