Summary

These GIS grids were produced from NOAA precipitation frequency estimates for North America based on precipitation data collected from 1816 to 2014. The grids provide data for the 2-, 5-, 10-, 25-, 50-, 100-, 200-, and 500-year recurrence intervals for a 24-hour duration. Grid values are in inches.
