Retrieval of the Profile of Stratospheric Aerosols from the Intensity of Skylight during Twilight Periods
用曙暮光时的天光光强反演平流层气溶胶散射系数廓线

Based on a serial study on twilight problems, this paper proposes a scheme for retrieving the vertical distribution of stratospheric aerosols using the intensity observations during twilight periods. After simulations and analyses of Koomen's twilight data by a Monte -Carlo code, a retrieval test was carried out using this data set and the retrieval results and errors were discussed. Results show that this method may provide an effective retrieval method for studying the long-term variation of stratospheric aerosols.
