| 摘 要： | 2013年1月12日-26日，利用大气超级站ALS300型激光雷达对重庆主城区大气进行了连续探测，分析了重污染形势期间的大气扩散条件及大气颗粒物时空分布等探测结果。分析表明，大气层结持续稳定，扩散条件差使得大气颗粒物浓度居高不下，大气能见度持续恶化；大气重污染期间PBL高度较低，平均为320～350m；大气颗粒物污染带处于100～400m高度范围；全国范围内异常的大气环流形势和重庆主城区独特的地形、气候特征是造成持续大气重污染形势的原因。

| Abstract: | Aimed at heavy air pollution of Chongqing urban area, a continuous detection experiment was performed using ALS300 lidar at the atmosphere observation super station from Jan. 12 to 26, 2013. The tempo- ral and spatial distribution of atmospheric particulate matter was analyzed with the data of lidar detection, as well as the atmospheric diffusion conditions. The results showed that the steady atmospheric stratification and poor dif- fusion condition were the efficient amse of sustained high particulate matter concentration, and the atmospheric visibility continued to deteriorate. The average PBL height was 320 -350 m during heavy air pollution, which was lower than usual. A pollution belt of particulate matter was in the range of 100 - 400 m. Nationwide anomaly of atmospheric circulation and unique climate and topography characteristics of Chongqing were the real causation of sustained heavy air pollution situation. |
