摘要:

使用LB10-D200激光雷达,对2006年4月北京地区天气连续监测,通过监测数据的分析,研究沙尘天气的大气垂直结构及其运动发展情况,同时与通过使用E-BAM贝塔沙尘监测仪器、AERONET、MODIS和DREAM预测模型等手段的分析结果进行综合对比分析。结果表明:4月份共有10dAOT浓度大于1,最高峰达到4;激光雷达监测结果和其他手段得到的结果具有良好的一致性,能精确地表达典型沙尘天气垂直大气的时空分布;沙尘层AOT对整个大气AOT的贡献率约为60%~80%。

Abstract:

In the paper, LB10-D200 lidar was used to continuously monitoring the atmosphere in Beijing during the April, 2006, and then to analyzed the collected data to reveal the vertical structure and movement of dust atmosphere. The E-BAM dust monitoring instrument, AERONET, MODIS and DREAM models were used to compare and analyze. The result was that: There were 10 days in April with the AOT more than 1,the highest reached 4. The results were consistent between lidar data and other monitoring methods. Lidar results could present the spatial-time structure of vertical dust layers. The dust AOT contributed about 60%~80% to the whole AOT.
