From: Exposure of the US population to extreme precipitation risk has increased due to climate change
Extreme precipitation changes in Arizona: (a) Elevation map, (b) percent change in 1-h extreme precipitation, and (c) return periods by County [the maps created by QGIS 3.32.3-Lima (https://qgis.org/en/site/)]. The percent change indicates a change of PFEs in the twenty-first century against the NOAA Atlas 14. The percent change is calculated by sub-district in each county. The return period is a converted return period of 1-in-100-year PFEs defined in the NOAA Atlas, based on the new PFEs8,11.
