About NOAA Atlas 14 (PFDS)
NOAA Atlas 14, served through the Precipitation Frequency Data Server, is the authoritative source of design rainfall for most of the United States: point precipitation depths and intensities across durations from 5 minutes to 60 days and return periods to 1,000 years, with confidence bounds, downloadable as tables, grids and IDF-ready data.
Every US drainage manual keys its storms to Atlas 14 volumes, so this is where hydrology sections actually start. (Its successor, NOAA Atlas 15, is in progress to address non-stationarity — worth watching for long-lived designs.)
