Abstract

In earlier 1960’s, Wei studied the physical processes of the Umkehr effect and made several fundamental contributions to the atmospheric remote sensing (Wei, 1962). Late in 1964, Wei et al(Wei et al, 1964) designed the Umkehr method<C> which has been used in Beijing and Kunming for about 10 years. This method is more objective one without using priori limitatiom conditions and has been proved with stable results (Wei, 1989). In Beijing station, we have obtained more than 200 ozone vertical profiles from Umkehr <C> with good quality since 1979.
