Abstract : This report describes a method for compacting, accessing, and objectively analyzing ceiling/visibility probability data. Unconditional cumulative probabilities over the southern half of West Germany are analyzed. The technique used to compact the data uses less than one-eighth of the computer storage normally required. The accuracy of the data was only slightly impaired. Three objective analysis algorithms were investigated; Barnes, Janota, and nearest neighbor. The Barnes method performed best. Independent data were estimated, using this technique with a mean error of 3.2 percent.
