底层大气探测激光雷达国内研究现状与进展（特邀）

激光雷达是一种主动遥感探测仪器，具有大探测范围、高时空分辨率与高精度的特点，在大气环境参数（气溶胶、CO₂及臭氧等）及气象参数（温度、水汽、压力及风速风向等）探测方面获得了广泛的应用。随着近些年民众对雾霾类大气现象及气候变化的广泛关注，国家环境治理与气象预报部门以及行业企业等对大气观测技术的迫切需求，大气探测激光雷达在国内得到了快速的发展，并且取得了较好的研究成果。文中总结介绍了近些年国内大气探测激光雷达的研究进展与发展现状。根据探测对象的不同，激光雷达有米散射激光雷达、拉曼探测激光雷达、高光谱分辨探测激光雷达和差分吸收探测激光雷达等，文章较全面地介绍了目前比较常见的激光雷达在大气探测应用中的优缺点及其在不同探测对象中的应用，最后对激光雷达面临的技术瓶颈进行了总结与探讨，并对激光雷达的发展趋势进行了展望。

Research status and progress of Lidar for atmosphere in China(Invited)

Lidar is an active remote sensing instrument,which has the characteristics of high precision and high spatial-temporal resolution.It has been widely used in the detection of atmospheric environmental parameters(aerosol,CO2,ozone,etc.)and meteorological parameters(temperature,water vapor,pressure,wind speed and direction,etc.).In recent years,atmospheric phenomena such as haze and climate change have been widely concerned by the public,and the national environmental governance and meteorological forecasting departments have an urgent demand for atmospheric observation technology.Atmospheric Lidar has been developed rapidly in China,and has achieved good research achievements.The research progress and development status of Lidar for atmospheric detection in recent years were introduced and summarized in this paper.According to the different detection objects detected by Lidars,Lidars can be classified as Mie scattering Lidar,Raman Lidar,high-spectralresolution Lidar,differential absorption Lidar and et al.The advantages and disadvantages of all kinds of atmospheric detection Lidars and their applications in different detection objects were comprehensively introduced in this paper.Finally,the bottlenecks of Lidar technology were summarized,and the development trend of Lidar was also prospected.
