Spreadsheet of change factors at 242 NOAA Atlas 14 stations in Florida derived from the Localized Constructed Analogues version 2 (LOCA2) downscaled climate dataset (CF_LOCA2_2080_to_historical.xlsx)
The Florida Flood Hub for Applied Research and Innovation and the U.S. Geological Survey have developed projected future change factors for precipitation depth-duration-frequency (DDF) curves at 242 NOAA Atlas 14 stations in Florida. The change factors were computed as the ratio of projected future to historical extreme-precipitation depths fitted to extreme-precipitation data from downscaled climate datasets using a constrained maximum likelihood (CML) approach as described in https://doi.org/10.3133/sir20225093. The change factors correspond to the period 2060-99 (centered in the year 2080) as compared to the 1966-2005 historical period.
A Microsoft Excel workbook is provided which tabulates change factors derived from the Localized Constructed Analogues version 2 (LOCA2) dataset at grid cells closest to National Oceanic and Atmospheric Administration (NOAA) Atlas 14 stations in Florida. The change factors were computed as the ratio of projected future to historical precipitation depths fitted to extreme-precipitation data using a constrained maximum likelihood approach. The change factors are tabulated by duration (1, 3, and 7 days) and return period (5, 10, 25, 50, 100, 200, and 500 years).
