| 摘 要： | 为研究北京地区大气PM10的变化规律和三维空间结构,文章基于Models3/CMAQ空气质量模式,利用北京及周边省市详细调查的污染源数据,采取双层网格嵌套技术建立起适用于北京及周边地区的大气PM10数值模拟系统。为了检验该模式系统的准确性和可靠性,文章将模拟结果与北京市城近郊区7个地面站近2500h的逐时地面监测数据以及一次典型污染过程的激光雷达垂直观测记录分别进行了对比分析,结果表明,该模式系统较好的反映了北京地区PM10浓度三维时空分布特征,是研究华北地区复杂地形下大气PM10传输及演变规律的一个有效工具。 |

| Abstract: | Seasonal variation and 3-D distribution of PM10 concentration over Beijing metropolitan region and surrounding area were investigated by the use of Models3/CMAQ modeling system,which was established based on the emission inventory of Beijing and around area.To validate the modeling system,approximately 2500 hours monitoring data from seven ground level monitoring stations as well as three LIDAR Monitors over Beijing were used to compare against the simulation results.It was indicated that the modeling syste... |
