Ring effect is defined as the phenomenon that the depth of solar Fraunhofer lines shallows caused by solar rotational Raman scattering of sunlight. Aerosol can change the atmospheric light paths of photons and atmospheric scattering properties, and then influence the filling-in of Fraunhofer lines, so we can retrieve the aerosol information from the intensity of Ring effect. Sensitivity of the Ring effect to optical parameters of aerosol is analyzed, including aerosol optical depth, single scattering albedo and asymmetry factor. A new method for determining aerosol optical properties by ground-based multi-axis differential optical absorption spectroscopy (MAX-DOAS) observation and the atmospheric radiative transfer model is developed. The MAX-DOAS retrieval result is in good agreement with the measurement result from sun photometer. The study shows that the Ring effect observed by ground-based MAX-DOAS can be used to detect the aerosol properties.
