| 摘 要： | East Asia is one of areas with larger sulfide emis-sions, and in recent years, more sulfur-rich gases are emitted into the atmosphere along with the rapid growth of economy. A great amount of sulfate aerosol produced in industrial activities not only degrades the environment but also affects the regional climate. In China, besides the sulfate aerosol produced, the dust particle is also one of main aerosols in the atmosphere. According to observa-tions, the soil-origin aerosol still poses the … |

| Abstract: | This paper presents a comprehensive observa-tion technique on derived aerosols data from mobile sun-photometer graph and Terra-Moderate Resolution Imaging Spectroradiometer (MODIS) observation. Research results suggest that after being treated by the variational technique with respect to sunphotometer observations, the Terra- MODIS remote sensing aerosol data are remarkably im-proved, thus for the first time revealing features of the influ-ence of aerosols and pollution emissions of Beijing and its adjoining areas (Hebei, Shandong, etc. provinces). The re-gional impact features of aerosols are related with the pe-ripheral U-shape topography of Beijing. Analyses with Hy-brid Single Particle Lagrangian Integrated Trajectory model (HYSPLIT-4) and meteorological data in the case studied confirm the pollutants diffusion process along the trajectory from the sources in the south-west region, and the regional aerosol impact features. |
