Abstract: A spherical shell model has been carried out to analyze the information content of Umkehr measurement of Brewer work wavelengths, and a new method considering the aerosol effects on ozone profile retrieval is given by using Brewer spectrophotometer. The new method which put the aerosol correction directly into Umkehr inversion algorithm is described in detail, and the aerosol optical thickness is used to calculate the aerosol correction coefficient. The Table Mountain data has been analyzed using this method. The results are in better agreement with other measurement results. Beijing data from January to March, 1991 are also processed. There exists an approximately linear relationship between stratospheric aerosol optical thickness and aerosol errors of each Umkehr layer produced by normal method without aerosol correction. The results with aerosol correction are well compared with other work
