本研究基于新编制的东亚地区黑碳气溶胶排放清查表，采用三维化学输送模拟系统研究了东亚地区春季黑碳气溶胶的输送和演化过程。模拟的黑碳气溶胶混合比例与地面站和船上收集的观测数据进行了比较。模拟值与观测值基本吻合，模式系统较好地捕捉了黑碳气溶胶浓度的时空变化特征，重现了观测到的许多重要特征。模式结果分析表明，东亚地区春季西北太平洋上空的间歇性远距离输送对黑碳气溶胶浓度分布起着重要作用。
In this study a three-dimensional chemical transport modeling system was applied to East Asia to investigate the transport and evolution processes of black carbon aerosol in the springtime based on a newly compiled regional emission inventory of black carbon aerosol. Simulated mixing ratios of black carbon aerosol were compared to observation data collected on ground stations and aboard a vessel. The comparison shows that simulated values were generally in good agreement with observed ones, and the model system captured the temporal and spatial variations in black carbon aerosol concentrations reasonably well, and reproduced many of the observed important features. Analysis of model results indicates that the intermittent long-range transport plays an important role in black carbon aerosol concentration distributions over the Northwestern Pacific during the springtime in East Asia.
