Application of the WRF-Hydro Modeling System for the Conterminous United States Using the Bias Adjusted Version of the CONUS404 Atmospheric Forcings (CONUS404BA), Water Years 1980-2022

This data release contains inputs for and outputs from a hydrologic simulation for the conterminous United States (CONUS) using the WRF-Hydro modeling system version 5.2.0 (Gochis and others, 2020). This simulation was developed to provide water budget estimates for the period 10/1/1979 to 9/30/2022 using the bias adjusted version of the CONUS404 (CONUS404BA) atmospheric forcings dataset (Zhang and others, 2024). The WRF-Hydro model input files are included within this data release and consist of two configuration files, two simulation restart files, nine parameter files, and six types of output files. Each output type has a file for every hour of the model simulation, except for the LDASOUT and RTOUT files, which are output every three hours. The WRF-Hydro model has been executed with two different lake/reservoir routing options: 1) Pass Through - which aggregates the inflows coming to the lake and placing it as the lake outflow (Qin = Qout), representing roughly a natural flow behavior; and 2) Level Pool - using level pool lake/reservoir routing techniques in the presence of a waterbody on the channel network. Therefore, for the lakes and channel outputs, there exists two sets of data. The Entity and Attribute element of the metadata file contains the data descriptions for all the variables in each of the six types of output files. Please refer to the Supplemental Information element of this metadata record for further information on this model application. A schematic of the directory and file structure of the model archive is described by the model_archive_directory_structure.txt file included in this data release below. All model files are archived on the U.S. Geological Survey's Open Storage Network pod and can be accessed using the instructions provided in the Dataset Access section of the U.S. Geological Survey's HyTEST JupyterBook (https://hytest-org.github.io/hytest/doc/About.html#). The report that describes the development of this model application is provided in the External Resources (RafieeiNasab and others, 2024a). A previously published model archive for an 11-year WRF-Hydro simulation for the period 2010 to 2021 which is described in RafieeiNasab and others (2024a) is provided in the External Resources below (RafieeiNasab and others, 2024b).
