大气气溶胶物理光学特性研究进展

Progress in the study of physic-optics characteristics of atmospheric aerosols

大气气溶胶粒子作为地气系统的重要组成成分之一,在紫外、可见到红外很宽的波段内对辐射传输产生影响,一方面通过对电磁波的散射和吸收作用,导致光波的能量衰减;另一方面则把吸收的能量转化为其本身的热能,起到加热大气的作用.这一过程在直接和间接的辐射气候效应的模拟、激光大气传输、高分辨率光谱研究、地基和空基遥感、大气辐射订正、环境监测技术、目标探测和识别、陆上交通和航空航海都有着重要作用.详细阐述了大气气溶胶物理光学特性近年来的研究进展,为气溶胶科学后续研究工作的更好开展提供参考.

Atmospheric aerosol particles, as one of the important members in the earth atmosphere, can influence the radiative transfer from violet and visible light to infrared in a wide wave band. On one hand, by scattering and absorption of electromagnetic waves, they can induce the energy attenuation of light waves; on the other hand, by turning the absorbed energy into the heat energy, they can heat up the atmosphere. This process directly or indirectly plays an important role in the simulation of radiate climate effect, the propagation of laser atmosphere, the high resolution spectrum, the ground and space remote sensing, the atmospheric correction, the environmental monitoring, the target detection and identification, and the overland traffics, aviation and navigation. We review the study of physics-optics characteristics of atmospheric aerosols, aiming at providing a reference for further study of atmospheric aerosols.
