激光/波谱技术促进了大气立体监测技术的发展，以光学探测和光谱数据解析为核心、以紫外、可见到红外全光谱为探测波段的各种高分辨率光学监技术，在中国逐渐实现了从近地面到100 km大气气象要素和大气痕量成分实时探测的能力，以及近地面到50 km大气多要素的实验模拟能力。光学技术以高灵敏度、高分辨率、高选择性、多组分以及实时等优势，在大气环境领域日益发挥作用，为研究大气污染演变与气象过程相互作用、大气细粒子污染和光化学烟雾形成机理等基础科学问题研究提供数据支持，为揭示城市和区域尺度的大气复合污染特征、量化其环境影响，提供科技支撑。

The constantly developing laser/spectrum technology has promoted the development of atmospheric stereoscopic monitoring technology. With optical detection and spectral data analysis at the core, various high-resolution optical monitoring technologies with ultraviolet-visible light-infrared "full spectra" as detection bands, the real-time monitoring of meteorological elements and atmospheric trace constituents from near-surface to 100 km, and the experimental simulations of atmospheric multi-factors from near-surface to 50 km have gradually developed in China. With its numerous advantages, such as high sensitivity, high resolution, high selectivity, multiple component, and provision of real-time data, optical technology plays an increasingly important role in the field of atmospheric environment in China. It provides data support for the research into basic scientific issues, such as the interaction between the evolution of atmospheric pollution and meteorological processes, the formation mechanism of atmospheric fine particle pollution and photochemical smog, and the interaction between atmospheric aerosol and cloud microphysical processes. Optical technology also offers technical support to reveal the formation mechanisms of combined atmospheric pollution and to quantize their environmental influence at urban and regional scales in China.
