This study attempts to design a minimum raingauge network for Uganda. Monthly rainfall totals from 102 stations within the period 1940-75 are used. Principal component analysis (PCA) was used first to delineate Uganda into homogeneous rainfall subdivisions. The station with the highest PCA-derived communality from each group of stations within each subdivision was then chosen to form the minimum network design. A minimum network of 14 stations was derived. Although less than 50% of the areal rainfall variance was explained in some subdivisions during some rainfall seasons, a minimum network design provides the best climatological data samples that are representative of all the unique rainfall characteristics over the region.
