Ring效应指大气中O₂和N₂分子对太阳光的转动拉曼散射导致太阳夫朗禾费线变浅(被填充)的现象。气溶胶能够改变光子在大气中的光程和大气散射性质，进而影响散射次数和转动拉曼散射几率，所以可以通过观测Ring效应强度获取气溶胶信息。研究了一种利用地基多轴差分吸收光谱(MAX-DOAS)仪器观测反演气溶胶信息的新方法，基于MAX-DOAS 仪器在晴朗天气下对大气Ring 效应进行观测，结合McArtim 大气辐射传输模型可以获取气溶胶消光廓线。将MAX-DOAS 反演气溶胶光学厚度结果和太阳光度计观测结果进行了对比，一致性较好。研究结果表明，基于地基MAX-DOAS观测大气Ring效应反演气溶胶消光廓线是可行的。

Ring effect is defined as the phenomenon that the depth of solar Fraunhofer lines in scattered light shallows (is filled up) and is caused by rotational Raman scattering by atmospheric O₂ and N₂ molecules. Aerosol can change the atmospheric light path of photons and atmospheric scattering properties, and then influence the scattering number and Roman scattering possibility, so the aerosol information can be retrieved from the observation of Ring effect. A new method for determining aerosol profile by ground- based multi axis differential optical absorption spectra(MAX-DOAS) observation is studied. Aerosol extinction profile information can be obtained through the MAX-DOAS observation under clear days and combination with McArtim.The comparison between retrieval result and measurement result from sunphotometer has a good agreement. The results show the retrieval of aerosol profile from Ring effect observed by ground-based MAX-DOAS is feasible.
