| 摘要： | Existing paved road dust emission estimation methods lack physical justification and show very weak correlation with observations. Long term {over one hour) integrated up-wind/down-wind PM10 sampling has poor ability to resolve paved road emissions. A new theoretical treatment of paved road dust dispersion is presented. Analysis of measurement and modeling processes indicates that real time measurements are needed to properly characterize paved road dust emissions. |
