Future 24-hour Depth-Duration-Frequency curves for selected U.S. cities

Extreme rainfall events can lead to catastrophic consequences such as widespread property damage or loss of lives. In engineering design, we take into account different characteristics of extreme events, such as average recurrence interval, duration and volume of rainfall delivered. We have so far relied on historical rainfall observations to estimate these characteristics, however, there is evidence that rainfall patterns in the future will look different from the past. Global Climate Models can be used to understand to some extent, the magnitude of these changes.

In this repository, we provide updated rainfall volumes for 24-hour duration storms using 5 different downscaled climate model datasets and for selected cities in the United States. For more information on the update process, please refer to the associated publication of this dataset.
