AB: The statistical properties of precipitation events from various satellite products are investigated for northern Africa during the rainy summer season. Different statistical measures, including correlation function and critical success indices, are employed. The spatial scales of interest range from 4 km to 100 km, and the temporal scales of interest range from instantaneous to monthly. The statistics are conditioned on different rainfall rates. The statistics clearly indicate the considerable geographical variability of precipitation variability. The results of this study will be useful for downscaling coarse precipitation fields, and for evaluating satellite-derived precipitation estimates.
