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.
