Input files and PRMS model-run components for the releases of the Alaska NHM-PRMS, 1980–2021

This data release contains inputs for and outputs from hydrologic simulations for the Alaska (AK) domain using the Precipitation Runoff Modeling System (PRMS) version 5.2.1.1 and the USGS National Hydrologic Model infrastructure (NHM, Regan and others, 2018). Historical simulations using the Daymet Version 4 gridded estimates of daily weather parameters (Thornton and others, 2020) were produced for the period 1980–2021. These data document the PRMS climate input data files for these simulations. Input files for the simulations include the PRMS parameter file and control file. The main landing page provides additional information and data dictionaries (parameters_data_dictionary.csv and control_data_dictionary.csv) that describe the parameter and control file values. Daymet forcings include precipitation and minimum and maximum temperature at a daily time-step. Measured streamflow data are included for 196 USGS streamgage locations for 1980-2021 (U.S. Geological Survey, 2022)., and for 89 streamgage locations form the Canadian Water Survey for 1980-2021 (HYDAT, 2024). for the Alaska Domain. CONTENTS OF THIS CHILD PAGE: 1. Precip.day = daily total precipitation climate-by-hydrologic response unit (CBH) file 2. Tmax.day = maximum daily temperature CBH file 3. Tmin.day = minimum daily temperature CBH file. 4. PRMS_5.2.1.1.zip = PRMS executable version 5.2.1.1. 5. sf_data = Streamflow data. 6. Ak_precalibration.control = Precalibration model control file. 7. AK_precalibration.param = Precalibration model parameter file. 8. AK_byHRU.control = byHRU model control file 9. AK_byHRU.param = byHRU model parameter file
