Return period estimate for the July 2022 rainfall event: red boxplot indicates the event will happen more frequently in the future (2022-2100) relative to other historical periods (black, blue, orange boxplots).
Top two rows show the NOAA Atlas 14 width of 90% confidence interval in designating a 1-in-1,000-year rainfall event at individual rain gauges. Bottom five rows show more precise estimates based on this study’s various methods.
Blended dataset for St. Louis (STL) and eastern Kentucky (EKY) includes over a century of observation data and 1,250 years of climate model ensemble data.
Estimates of 24-hr precipitation depth constituting events of differing frequencies. Red and green lines show 90% confidence interval, which spans more than 7 inches at the 1-in-1,000-year event level.
