差分光学吸收光谱技术(DOAS)经过三十多年的发展,已经广泛用于地基、空基和卫星平台的大气痕量气体观测。 目前, DOAS技术在大气气溶胶光学厚度、消光系数、粒径分布、污染类型等监测领域得到了很大的发展,为大 气环境监测、大气化学研究提供了新的手段和方法。在分别回顾主动DOAS技术监测近地面气溶胶以及被动DOAS技 术反演垂直方向上气溶胶光学参数等研究的基础上,对DOAS技术监测气溶胶的研究领域技术发展提出新思路。

After more than three decades’ development, the differential optical absorption spectroscopy (DOAS) method is widely used to measure the atmospheric trace gases in forms of ground based, air borne and satellite platform. Recently, the DOAS technique made great progresses in atmospheric aerosol measurement, including aerosol optical depth (AOD), extinction coefficient, size distribution and pollution type, which provides a new method for atmospheric environment monitoring and atmospheric chemistry research. Studies about the active DOAS technique to measure ground surface aerosol optical parameters and passive technique to retrieve vertical aerosol optical properties were reviewed, respectively. Afterwards, new ideas for the research on the aerosol monitoring by the DOAS technique were put forward.
