The Precipitation Frequency Data Server (PFDS) is a point-and-click interface developed to deliver NOAA Atlas 14 precipitation frequency estimates and associated information.

To access point precipitation frequency estimates, select precipitation depth or intensity. Choose a state, and then select a station, or adjust the crosshair on the map. Data tables and graphs appear directly below the map. Links to supplementary information (such as ASCII grids of estimates, associated temporal distributions of heavy rainfall, time series data at observation sites, cartographic maps, etc.) are also available.

Links to additional information related to precipitation frequency are available in the navigation bar on the left side of the screen. Inquiries about the PFDS can be directed to hdsc.questions@noaa.gov (the NOAA Atlas 14 official email address).
