High-Resolution Precipitation Projections for the South Central U.S.

Precipitation-related indicators for seasonal precipiation, extreme precipiation, and drought have been generated for 8701 weather stations covering the entire United States, and for a 198x337 grid (on a resolution of 1/16 th degree) covering the South Central region from the future downscaled projections using the Asynchronous Regional Regression Model. The data covers the period from 1950 to 2100. The high-resolution future projections are statistically downscaled from simulations by 12 global climate models from the Coupled Model Intercomparison Project phase 5 (ACCESS1-0, ACCESS1-3, CCSM4, CMCC-CM, CNRM-CM5, CSIRO-Mk3.6.0, MPI-ESM-LR, HadGEM2-CC, INMCM4, IPSL-CM5A-LR, MIROC5 and MRI-CGCM under the lower Representative Concentration Pathway (RCP) 4.5 and the higher RCP 8.5 scenarios. The time slice dataset is derived over the pre-determined 30-year periods, including 1950-1979, 1980-2009, 2010-2039, 2040-2069, and 2070-2099. Each time slice is represented in the data as July 7th of the first year of the slice.
