Retrieval of the optical parameters of Venus atmosphere from the data obtained with Automatic Interplanetary Stations "Venera"

interplanetary automatic stations is growing again. Thus we return to observations accomplished in 70th years of last century. Data of spectrophotometric observations, obtained from the board of Automatic Interplanetary Stations "Venera", are used for the interpretation on the base of analytical method with the purpose of the retrieval of single scattering albedo and optical thickness at the different levels of measurements. The method of choosing optical parameters as points of intersection curves of plotting data was applied together with the method of the inverse asymptotic formulas for atmosphere of big optical thickness and weak absorption. The comparative error analysis of both approaches is accomplished. Exactness of used methods are indicated. Optical parameters of the Venus atmosphere are obtained.
