提出了通过改变激光束仰角的斜程探测得到气溶胶空间二维分布的方案。利用自行研制的Mie散射激光雷达系统对合肥西郊上空的大气气溶胶进行了连续的斜程探测,并通过相应的数据处理方法,得到气溶胶消光系数二维分布图及其随时间的演变图。给出了2005年12月2日的典型探测结果,这些结果不仅全面直观地反映了大气空间某一纵向剖面的气溶胶消光系数分布情况,而且清楚地显示了这一分布随时间的整体变化趋势,这对于实时的大气环境监测具有重要意义。
A scheme of two-dimensional distribution of aerosol space is proposed by changing the slope of elevation of laser beam. Atmospheric aerosol over the western suburbs of Hefei was continuously traced using the Mie scattering lidar system developed by ourselves and the two-dimensional distribution of aerosol extinction coefficient and its evolution with time were obtained by corresponding data processing methods Figure The typical detection results of December 2, 2005 are given. These results not only reflect the distribution of aerosol extinction coefficients in a longitudinal section of the atmospheric space in a comprehensive and intuitive way, but also clearly show the overall trend of the distribution with time , Which is of great significance for real-time monitoring of the atmospheric environment.
