2013年11月25日至12月9日，利用大气超级站ALS300型偏振Mie散射激光雷达对重庆主城区大气进行了连续探测，分析了持续污染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：太阳辐射和地面辐射的减弱，极差的扩散条件，以及稳定的大气层结等多重因素导致大气颗粒物持续累积，能见度持续恶化；持续污染期间PBL高度较低，基本维持在150至400m之间，且几乎无明显变化，整个污染带在0至400m的高度范围。

A continuous detection was conducted from 25th November to 9th December, 2013 in Chongqing ur-ban area using ALS-3000 polarization Mie scattering lidar. Air diffusion condition as well as the time and space dis-tribution of atmospheric particulates were analyzed. It indicated that weak solar radiation, bad diffusion condition and stable atmospheric stratification together led to continuous accumulation of particulates and persistent deteriora-tion of visibility. During pollution period, the height of planetary boundary layer was low, ranging from 150m to 400m and no obvious variations were found;pollution zone ranged from 0m to 400m.
