For a description of the methodology used in compiling this catalog, see Kahn, JGR 89, 6671-6688, 1984. Cloud occurrences were compiled by examining images for specific cloud morphologies, examining the same area at different times, utilizing limb images, and consulting photomosaics to determine the spatial relations of cloud obscurations. Note that approximately 7% of the cataloged images are ambiguous (3 teams of observers were used to compile the catalog) and that errors exist in the identification of cloud streets at high northern latitudes (the similar appearances of cloud streets and fields of sand dunes made identification difficult).
