Interpretive Summary:

Technical Abstract: The Wind Erosion Prediction System (WEPS) was designed for ease of use that includes simple inputs wherever possible. The inputs required for the WEPS science model are contained in five files. Specific file formats and variables are required for the master WEPS Run input file, the WEPS Soil Initial Field Conditions (IFC) file containing both the intrinsic soil properties and the initial values for the temporal soil and surface properties, the Management/Crop Rotation file consisting of the management operations and their dates, and two climate (CLIGEN and WINDGEN) generated output files consisting of the daily climatic and hourly wind parameters. The master input file is the WEPS Run file, which specifies the filenames for the Soil IFC file, the Management/Crop Rotation file, the two climate files (CLIGEN and WINDGEN generator output formatted), and the location information, simulation region dimensions, and wind barrier information if any are present. In addition, all WEPS command line arguments are fully described. WEPS inputs and command line arguments are simplified within the user interface wherever feasible for minimal user supplied inputs.
