Extreme precipitation datasets for the contiguous US, from gridded analyses and a convection-permitting model simulation

This is a collection of datasets that show where and when precipitation exceeded average recurrence interval (ARI) thresholds at durations from 24-72 hours over the contiguous US (CONUS). Specifically, included are 100- and 1000-yr exceedances (i.e., precipitation accumulations with annual exceedance probabilities of ≤1% and ≤0.1%, respectively) from these precipitation datasets: NOAA's Stage IV analysis, 2002-2024 Parameter-Elevation Regressions on Independent Slopes Model (PRISM), 1981-2024 NOAA Multi-Radar Multi-Sensor (MRMS) system, 2018-2024 CONUS404 simulation, 1981-2024
