 The study highlights the challenges associated with using weather radar data to investigate extreme precipitation, including short radar records, and uncertainty in radar-based QPE measurements. It also demonstrates the importance of high resolution, weather radar observations, for resolving small-scale rainfall events, and the necessity of radar-based climatological data sets for understanding the characteristics of extreme precipitation. The study shows that only a small percentage of heavy precipitation events are captured by precipitation-gaging stations, highlighting the importance of radar-based monitoring for hydrologic extremes.
