<p dir="ltr">SWPar4.5 is a gridded parameterization for the stochastic weather generator called CLIGEN, commonly used to drive soil erosion models and other applications. Three global climate models from the IPCC ensemble for representative concentration pathway 4.5 (RCP4.5) are parameterized for the states of Nevada, Utah, Arizona, and New Mexico. The spatial resolution is 30 arc seconds with a series of separate parameter sets representing 30-year windows at decadal intervals throughout the simulation period. To assist with querying and data extraction, command-line executables are included that create formatted CLIGEN parameter text files for a location/time of interest and GeoTIFF maps from the ESRI GDBs that are available here.</p><p dir="ltr"><br></p><hr><p dir="ltr"><i>For inquiries regarding the contents of this dataset, please contact the Corresponding Author listed in the README.txt file.
