MR9/VO1/VO2 MARS IMAGING SCIENCE SUBSYSTEM/VIS 5 CLOUD V1.0

This data set consists of a catalog of clouds observed in Mariner 9 and Viking Orbiter images. Seven 'cloud types' were defined according to easily observable objective morphologic criteria. The entire Mariner 9 and Viking Orbiter image data sets (approximately 7400 and over 50000 images, respectively) were examined at least twice, by two separate observers. 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.
