Summary

The South Florida Water Management District (SFWMD) and the U.S. Geological Survey have developed projected future change factors for precipitation depth-duration-frequency (DDF) curves at 174 National Oceanic and Atmospheric Administration (NOAA) Atlas 14 stations in central and south Florida. The change factors were computed as the ratio of projected future to historical extreme precipitation depths fitted to extreme precipitation data from various downscaled climate datasets using a constrained maximum likelihood (CML) approach. The change factors correspond to the period 2050-2089 (centered in the year 2070) as compared to the 1966-2005 historical period. An areal reduction factor (ARF) is computed to convert rainfall statistics [...]

Purpose

The primary purpose of this table is to tabulate the areal reduction factors used in this project to adjust return levels of precipitation depths from area-scale to station-scale. This project is a cooperative effort between the U.S. Geological Survey (USGS) and the South Florida Water Management District (SFWMD).
