This data release contains inputs for and outputs from hydrologic simulations for the Hawai‘i (HI) 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). Simulated streamflow stored in this child item (NHM-PRMS_data_release.nc) and statistics at streamgages (gage_stats_gm.csv) are provided for one pre-calibration and two calibration configurations (byHRU, and byPOIobs). The streamgage statistics file provides the Nash-Sutcliffe Efficiency Index between observed and simulated streamflow using daily, log of daily, monthly, and log of monthly values along with the bias, and drainage area for the model and streamgage for each Point-of-Interest (POI) in the simulation. The simulated streamflow file contains simulated and observed streamflow values for each POI in the simulation for 1980-2021. The main landing page provides additional information about the calibrations and a data dictionary (simulated_streamflow_data_dictionary.csv) which describes the simulated streamflow variables. CONTENTS OF THIS CHILD PAGE: 1. HI_stats_precalibration.zip = Folder containing simulated streamflow and statistics at streamgages from the precalibration release run for the HI domain. 2. HI_stats_byHRU.zip = Folder containing simulated streamflow and statistics at streamgages from the byHRU release run for the HI domain. 3.
