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.
