The global circulation model of the RAND Climate Dynamics Study is briefly described. The present method of interpretation of data from this program is discussed; in many cases the hard copy is difficult to interpret because the lines defining the contour intervals overlap, coincide, and become indistinguishable. Some possible alternative or complementary techniques using both pseudocolor and false color for display of these data are presented, in which digital data are transformed to black-and-white intermediate film strips and subsequently combined to produce color images. A method of testing our new techniques to determine their merit is suggested.
