Abstract. The Wind Erosion Prediction System (WEPS) is a physical process-based wind erosion model developed by the United States Department of Agriculture - Agricultural Research Service (USDA-ARS). WEPS simulates climate and management driven changes to the surface, vegetation and soil on a daily basis and estimates erosion losses when surface conditions and wind speeds are sufficient for soil movement. WEPS was released in 2010 to USDA-Natural Resources Conservation Service (USDA-NRCS) and is used to assist land managers in controlling wind erosion, establishing field-level plans for soil conservation and to determine wind erosion susceptibility as a part of national conservation programs to conserve the soil resource. The WEPS interface allows easy user access to national scale input data.  Four primary inputs are required to setup and execute a WEPS run: a) field dimensions; b) field location, which automatically determines which climate data to use; c) a representative soil; and d) the sequence of management practices applied on the site.  These inputs access a significant amount of data currently stored locally.  Maintaining this data on every computer running WEPS and keeping it current were issues NRCS wanted to address. To address these concerns, remote access functionality was incorporated into WEPS to deliver the climate and wind data, as well as soil, operation, crop/residue and management records.  In addition, WebStart WEPS also features the option of running the WEPS science model components remotely, "in the cloud", as web services. Using the Java WebStart framework provided a simplified delivery mechanism to the user‘s computer and offered automatic updating capability.
