Output Data by HUC4 Sub-basin for Hydrologic Simulations of the CONUS using the NHM-PRMS, 1950-2010, Maurer Calibration, Static Parameters

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2024-05-15T00:00:00Z
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 (NHM, Regan and others, 2018). Historical simulations using the Maurer forcings (Maurer and others, 2002) were conducted for the period 1950-2010. This metadata record documents the simulation output files for simulations ran using the static parameters file. The output files are aggregated at the HUC4 level and are grouped and downloadable by HUC2 hydrologic region. Each zip folder contains identical information, just for a different region and set of hydrologic response units (HRUs) and stream segments. The specific zip folder contents include model unit information for the HRUs and stream segments, HRU-based output variables of daily actual evapotranspiration (hru_actet), runoff (hru_outflow), precipitation (hru_ppt), potential evapotranspiration (potet), minimum air temperature (tminf) and maximum air temperature (tmaxf), and the segment-based output variable of streamflow (seg_outflow).
