In recent years, extreme rainfall events are increasing both in number and intensity, but it is hard to identify specific trends and dynamics at regional level due to the strong variability of this process in both time and space. With this aim, the present work attempts to assess a detailed description of sub-daily extreme rainfall patterns and trends over the Campania Region. For this reason, records from all available rainfall stations have been collected and used to build a dataset of hourly rainfall annual maxima, which have been also extended using gap-filling techniques. The assembled rainfall database allowed to improve our understanding about rainfall dynamics and quantify trends of annual maxima over the region.

Keywords: Annual Maximum Rainfall, Gap-Filling Techniques, Spatially-Constrained Ordinary Kriging, Rainfall Trends, Change-Point Detection.
