Application of the National Hydrologic Model Infrastructure (NHM) with the Precipitation-Runoff Modeling System (PRMS) and Geospatial Fabric version 1.1, 1980-2021, CONUS404BA
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 5.2.1 and the USGS National Hydrologic Model infrastructure (NHM, Regan and others, 2018). These simulations were developed to provide estimates of the water budget for the period 1980 to 2021 for one pre-calibration and three calibration configurations: 1) calibration by hydrologic response unit (byHRU), 2) calibration by select headwaters (byHW), and 3) calibration by select headwaters with streamflow observations (byHWobs). The four versions of model parameters and associated model output included in this data release are described in Hay and others (2023). The first three years of the simulations are considered “model initialization” and should not be included in any subsequent analysis. Model input files, located on the “Input Data for Hydrologic Simulations of the CONUS using the NHM-PRMS version 1.1, CONUS404BA Calibration” child page, include ASCII formatted PRMS input files of 1) daily time step atmospheric forcings of minimum air temperature (tmin.zip), maximum air temperature (tmax.zip), and precipitation accumulation (precip.zip), 2) four parameter files for the different calibration versions (c404BA_precal_myparam.zip, c404BA_byHRU_myparam.zip, c404BA_byHW_myparam.zip, and c404BA_byHWobs_myparam.zip), 3) a PRMS control file that provides the simulation configuration information (NHM-PRMS_data_release.control), 4) and the PRMS data file that includes time series of streamflow observations (sf_data.zip). Descriptions of model input parameters are included in the parameters_data_dictionary.csv file on this main page. Descriptions of control file parameters are included in the control_data_dictionary.csv file on this main page. Additional information about the model calibration and associated parameters is provided in Hay and others (2023). Additional information about the bias-adjusted CONUS404 (CONUS404BA) atmospheric forcings used for the model application is provided in Zhang and others (2024). Model output files, located on the “Output Data for Hydrologic Simulations of the CONUS using the NHM-PRMS version 1.1, CONUS404BA Calibration” child page, include 18 PRMS output variables for each of the four model simulations corresponding with the four input parameter files (pre-calibration, byHRU, byHW, and byHWobs). Each NetCDF format output file contains daily time step outputs for the period 1980-2021 for each hydrologic response unit or stream segment in the model application. Descriptions of model output variables are included in the output_variables_data_dictionary.csv file on this main page. Streamflow statistics of model performance at selected streamgages are located on the “Simulated streamflow and statistics at streamgages for NHM CONUS CONUS404BA Calibrations, 1980-2021” child page. Each of the four model simulations has an associated csv file of streamflow statistics (gage_stats_c404-bc_<run>.csv) and a NetCDF file of daily streamflow at each streamgage (NHM-PRMS_data_release.nc). Descriptions of the streamflow files are included in the simulated_streamflow_data_dictionary.csv file on this main page.

공공데이터포털
This data release contains output of the initial calibration of the conterminous United States (CONUS) application of the Precipitation-Runoff Modeling System (PRMS) as implemented in the National Hydrologic Model (NHM) infrastructure (Regan et al, 2018). The PRMS version 5.0.0 hydrologic simulation code was used with the accompanying parameter files in the NHM infrastructure to produce the attached output files. Model input climate drivers include climate data derived from the Daymet gridded data set version 2 (Thornton et al., 2014) with values spatially-distributed to the HRUs using the USGS Geo Data Portal (https://cida.usgs.gov/gdp/; Blodgett et al., 2011). The parameter values are maintained in the National Hydrologic Model Parameter Database (NhmParamDb; Driscoll et al., 2017. The parameter file used to produce these model results is attached (NHM-PRMS.zip). CONUS-scale parameter calibration for the USGS National Hydrologic Model (NHM) infrastructure application of the Precipitation-Runoff Modeling System (NHM-PRMS) was conducted using five baseline data sets derived from multiple sources for each of the NHM’s 109,951 hydrologic response units (HRU) on time scales from annual to daily. A multiple-objective, step-wise, automated calibration procedure was used to identify the ‘optimal’ set of parameters for each HRU. This produced spatially distributed parameters for the CONUS using a calibration procedure termed ‘byHRU’ calibration. The NHM-PRMS simulations, with the byHRU calibrated parameters, were conducted with the same configuration for a time period from October 1, 1980 to December 31, 2016. The first three years of the simulations are should be considered ‘model spin up’ and not included in any subsequent analysis. Table 1 (attached) lists the output variables included in this data release. The individual *.csv files follow a naming convention of using an abbreviation for the spatial dimension of the model output (nhru or nsegment) _variable name.csv. The variable names included are defined further in Table 1. The structure of each output file includes a header line which labels the columns by the spatial unit (hru or stream segment) identification number and each row has the date followed by either 109951 or 56460 values, depending the output variable dimension nhru or nsegment, respectively. See table 1-10 in Regan and LaFontaine (2017) for a description of the variables included in this file. To distribute parameter and output values spatially, a join can be completed by using the nhru_ID or nseg_ID from the variable and the hru_ID from the national-extent Geospatial Fabric. This research used resources provided by the Core Science Analytics, Synthesis, & Libraries (CSASL) Advanced Research Computing (ARC) group at the U.S. Geological Survey.

공공데이터포털
This data release contains inputs and outputs for hydrologic simulations of the conterminous United States (CONUS) using the National Hydrologic Model (NHM) application of the Precipitation Runoff Modeling System (PRMS) in ASCII and binary format and explanatory graphics in pdf format. These simulations were developed to provide estimates of water availability for historical conditions for the period October 1, 1980 to September 30, 2016 for five different calibration configurations; the first three years of the simulation should be considered the initialization period and should not be used for subsequent analysis. The five versions of model parameters and associated model output included in this data release are described in table 1 and in the Supplemental Information section of this metadata record. Table 2 provides information about the baseline datasets used for model calibration for each of the five parameter configurations. Figure 1 shows a schematic of the multi-step calibration procedure used to develop the model parameters. Table 3 describes the 36 model output variables that are included in the five attached folders. Five .tar folders are named according to the simulation configuration in table 1 and include the 36-model output variable files. Table 4 provides information about the 8,274 streamgage locations that are included in the NHM-PRMS. The NHM-PRMS parameter and control files for each of the five simulations are located on the child pages associated with this data release. The PRMS climate forcing input files for the simulations are in the DAYMET_CBH.zip folder. Summary files by streamgage of measured and simulated streamflow for the byHRU, byHRU_musk, and byHRU_musk_obs simulations are in the Streamgage_location_simulations_5999.zip folder. Any time series data in the model output files prior to the October 1, 1983 start date should be considered part of the model initialization period and should not be used. Please refer to the Supplemental Information element of this metadata record for more information about the model calibration, inputs, outputs, and summaries included in this data release.
