| 英文摘要 | Based on simulated major aerosol concentrations (e.g., sulfate, nitrate, ammonium, organic carbon, black carbon, and sea salt) over east asia during the year 2005 by using the multi-scale air quality modeling system (rams-cmaq), the aerosol optical depth (aod) was calculated by the reconstruction mass-extinction method and then analyzed to explore its characteristics in temporal-spatial distributions. for evaluating the model performances, simulated aod values were compared against observations at stations of the aerosol robotic network (aeronet) and the chinese sun hazemeter network (cshnet). the comparison shows that the model can well reproduce observed temporal and spatial features of aod, especially in natural environment. however, the simulated aod values are underestimated over urban and suburban regions with dense human activities. analysis of simulation results indicates that aod varies significantly in time and space, and generally, aod values are lower in summer and higher in winter. excluding the contribution from soil dust aerosols, high aod values (over 0.8) are found over the sichuan basin, south china, and central china in several months, while low values (less than 0.2) are over northern and western areas of east asia and southern sea regions. analysis also shows that aerosols such as sulfate, nitrate, and ammonium are main contributors to aod in east asia, and their contributions are over 80% in most high aod areas, while black carbon aerosols play an important role in northern china where dense human activities exist, especially in the winter time. |
