Atlas 14 Program

Developer/Partners: NOAA (2004)

Relevant Hazard/Threat(s): Precipitation

Intent: Provide precipitation frequency estimates for US and affiliated territories

NOAA Atlas 14 is the official peer-reviewed record of precipitation frequency estimates. Atlas 14 information quantifies the precipitation amount, at a particular location and for a given duration that qualifies as a "NN-year" precipitation event (i.e. it has a 1-in-NN chance of being exceeded in any given year). It is used for official design, planning, and management work. It is funded by affected states and other users on a cost-reimbursable basis.

Inputs: Information from NWS stations around the country
Outputs: Precipitation frequency, probable max precipitation

Does not yet include the Pacific Northwest region but will shortly work on it
