This data release contains inputs for and outputs from hydrologic simulations for the conterminous United States (CONUS) using the Precipitation Runoff Modeling System (PRMS) version 5.1.0 and the USGS National Hydrologic Model Infrastructure (NHMI, Regan and others, 2018). These simulations were developed to provide estimates of the water budget for the period 1950 to 2010. Specific file types include: 1) input atmospheric forcings of minimum air temperature, maximum air temperature, and daily precipitation accumulation derived from a gridded observation-based dataset developed by Maurer and others (2002), 2) input parameter files for static and dynamic land cover conditions, and 3) output files of simulated water budget components for each hydrologic response unit and stream segment. Figure 1 shows the calibration methodology that was used for the model application (see LaFontaine and others, 2019 for additional information). Table 1 lists the streamgages that are included in the model application. Table 2 lists the calibration datasets that were used in addition to USGS measured streamflow. The first three years of the simulations are considered 'model initialization' and should not be included in any subsequent analsysis.
