The frequency of extreme rainfall intensities over a 24-hour duration

These GIS grids were produced from NOAA and NRCC precipitation frequency estimates for North America based on precipitation data collected from 1816 to 2014. The grids provide information for durations from 24-hour and for recurrence periods of 2 year through 500 years. Grid value units are inches * 1000.
