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 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.
Geospatial data provided in an ArcGIS shapefile are described herein. The shapefile shows the locations of NOAA Atlas 14 stations in central and south Florida for which depth-duration-frequency curves and change factors of precipitation depths were developed as part of this project. For more information about the stations, see Table 1 of Datasets_station_information.xlsx.
